Write the equation y=3/4x-4 in standard form
The equation 3x - 4y = 16 is now in standard form, where A = 3, B = -4, and C = 16.
To convert the equation y = (3/4)x - 4 into standard form, we need to eliminate any fractions and rewrite it in the form Ax + By = C, where A, B, and C are integers.
The given equation is already almost in standard form, but we can proceed with the following steps:
Step 1: Multiply both sides by 4 to eliminate the fraction:
4y = 3x - 16
Step 2: Move all terms to one side of the equation to have zero on the other side:
3x - 4y = 16
The equation 3x - 4y = 16 is now in standard form, where A = 3, B = -4, and C = 16.

Complete Question
A recipe for 12 waffles calls for 1 1/2 cups of milk, 2 1/4 cups of flour, and 1 1/3 cups of other ingredients.
Answer:
A 5 1/12 cups of ingredients
B 10 1/6 cups of ingredients
C The total amount of ingredients for 12 waffles would increase from the original recipe.
D 7.56 or 7 5/9 recipes
Step-by-step explanation:
A... What is the total number of cups of ingredients needed for 12 waffles?...
The total number of cups of ingredients needed =
1 1/2 cups of milk + 2 1/4 cups of flour + 1 1/3 cups of other ingredients
(1 + 2 + 1) + (1/2 + 1/4 +1/3)
4 + ( 6 + 3 + 4/12)
4 + (13/12)
4 + (1 1/12)
= 5 1/12 cups of ingredients
B... What is the total number of cups of ingredients needed for 36 waffles? ....
If 12 waffles requires = 5 1/12 cups of ingredients
36 waffles =
Cross Multiply
= (36 waffles × 5 1 /12)/12 waffles
= 10 1/6 cups of ingredients
C... If the milk is reduced to 1 cup and the amount of 'other ingredients' (not including the flour) is increased to 2 cups, would the total amount of ingredients for 12 waffles increase or decrease from the original recipe?
Justify your thinking...
Original recipe.
A recipe for 12 waffles calls for 1 1/2 cups of milk, 2 1/4 cups of flour, and 1 1/3 cups of other ingredients = total of 5 1/12 cups of ingredients
Current recipe
1 cup of milk + 2 1/4 cups of flour + 2 cups of other ingredients
1 + 2 + 2 + (1/4)
5 1/4 cups of ingredients
Therefore, total amount of ingredients for 12 waffles would increase from the original recipe. This is because when you subtract 5 1/12 from 5 1/4 you get a difference of 1/6 cups
5 1/4 - 5 1/12 = 1/6
D... If a baker has a 5 pound bag of flour, which is approximately 17 cups of flour, how many complete recipes for 12 waffles can the baker make?... Justify your thinking...
The original recipe has 2 1/4 cups of flour as its quantity for 12 waffles
Hence:
2 1/4 cups of flour = 12 waffles
17 cups =
17 × 12/2 1/4
= 204÷ 2 1/4
= 204 ÷ 9/4
= 204 × 4/9
= 90.666666667 or 90 2/3 Waffles
If = 12 waffles = 1 recipe
90 2/3 waffles =
7.56 or 7 5/9 recipes
Given
Total no. of waffles required = 12
No. of cups of milk = [tex]1\frac{1}{2}[/tex]
No. of cups of flour = [tex]2\frac{1}{4}[/tex]
No. of cups of other ingredients = [tex]1\frac{1}{3}[/tex]
The total number of cups of ingredients needed for 12 waffles =
No. of cups of milk + no. of cups of flour + no. of cup of other ingredients
= [tex]( 1+ 2+ 1 ) ( \frac{1}{2} + \frac{1}{4} + \frac{1}{3} )[/tex]
= [tex](4) + ( \frac{6+3+4}{12} )\\\\= (4) +(\frac{13}{12} \\\\= \frac{48+13}{12} \\\\= \frac{61}{12}[/tex]
The total number of cups of ingredients needed for 12 waffles is [tex]\frac{61}{12}[/tex].
The total number of cups of ingredients needed for 36 waffles=
= The total number of cups of ingredients needed for 36 waffles cups of ingredients.
If the milk is reduced to 1 cup and the amount of 'other ingredients' (not including the flour) is increase or decrease in recipe.A recipe for 12 waffles calls for [tex]1\frac{1}{2}[/tex] cups of milk, [tex]2\frac{1}{4}[/tex] cups of flour, and [tex]1\frac{1}{3}[/tex]cups of other ingredients = total of [tex]5\frac{1}{12}[/tex] cups of ingredients
Current recipe
= 1 cup of 2 milk + cups of flour + 2 cups of other ingredients
= 1 + 2 + 2 + ()
= cups of ingredients
Therefore, total amount of ingredients for 12 waffles would increase from the original recipe. This is because when you subtract [tex]5\frac{1}{12}[/tex] from [tex]5\frac{1}{4}[/tex] you get a difference of [tex]\frac{1}{6}[/tex] cups.
[tex]5\frac{1}{4}[/tex] - [tex]5\frac{1}{12}[/tex] = [tex]\frac{1}{6}[/tex]

Quadrilateral ABCD is a parallelogram. Determine the measure of Angle A
A) 96°
B) 52°
C) 39°
D) 78°
Answer:
[tex]\huge\boxed{\text{(A)}\ 96 \textdegree}[/tex]
Step-by-step explanation:
A parallelogram has two pairs of identical angles.
The identical angles will be directly opposite from each other.
This means that:
Angle C = Angle AAngle D = Angle BTherefore, we can say that Angle A is 3x degrees and Angle B is x+52 degrees.
It's also important to note that all angles in a quadrilateral add up to 360°.
Since we know the measure of each angle, we can add up the expressions for each and find x.
[tex]3x + 3x + (x+52) + (x+52) = 360[/tex]
Let's simplify this equation.
[tex]6x+(x+52)+(x+52)=360[/tex] [tex]8x+104=360[/tex] [tex]8x=256[/tex] [tex]x=32[/tex]Now that we know the value of x, let's use it to find the measure of Angle A.
We already proved earlier that Angle C is equivalent to Angle A. Since we know the expression for Angle C (3x) it'll be the same for angle A.
[tex]3(32)=96[/tex]
So A is 96°

A building that is 300 m
tall casts a 270 m
shadow. At the same
time, a different building
casts an 90 m shadow.
How tall is the building?
Answer:
10m
Step-by-step explanation:
we can use the cross multiply method.
300m = 270m
x m = 90m
270x = 300 x 90
270x = 2700
x = 10
so the buliding is 10m tall

In Psychology 101, the ratio of the number of girls to the number of boys is $3:1$. After one girl drops the class and three more boys sign up, the ratio of the number of girls to the number of boys becomes $5:2$. How many students are in the class after these changes?
Answer:
There are 68 students in the class after these changes.
Step-by-step explanation:
g = number of girls
b = number of boys
Because the ratio of girls to boys is 3:1, initally the equation was
g = 3b
Finally, we have
g-1 girls because one girl dropped the class
b+3 boys because three more boys signed up
Because the new ratio of girls to boys is 5:2, the new equation is
(g - 1)/(b + 3) = 5/2
Cross multiply.
2(g - 1) = 5(b + 3)
2g - 2 = 5b + 15
2g - 5b = 17
Then, substitute g (which is 3b because the first equation was g = 3b)
2(3b) - 5b = 17
b = 17
g = 3b = 3*17 = 51
g = 51
The final number of students in the class = 17 + 51 = 68

We can assume angles 102° and angles 0 and 42° are alternate interior angles.
So, to solve for 0, we must add this unknown angle to 42° and make it equal to 102°;
Let's make '0', x(our variable we solve for)
x + 42 = 102

When multiplying two variables, how is using the
Distributive Property similar to using a table?
Newton's third law states that if object A exerts a force on object B, object B must respond with a force of equal size and in the opposite direction. This law reflects nature's symmetry: forces always exist in pairs, and one body cannot exert a force on another without experiencing one.
The distributive property of multiplication over addition can be used when you multiply a number by a sum. For example, suppose you want to multiply 3 by the sum of 10 + 2. 3(10 + 2) = ? According to this property, you can add the numbers and then multiply by 3.

Step-by-step explanation:
the nth term of an arithmetic sequence is
[tex]u_{n}[/tex] = u₁ + (n - 1)d
given u₂₀ = 100 and u₂₅ = 115 , then
u₁ + 19d = 100 → (1)
u₁ + 24d = 115 → (2)
subtract (1) from (2) term by term to eliminate u₁
0 + 5d = 15
5d = 15 ( divide both sides by 5 )
d = 3
substitute d = 3 into (1) and solve for u₁
u₁ + 19(3) = 100
u₁ + 57 = 100 ( subtract 57 from both sides )
u₁ = 43
Answer:
a) u₁ = 43, d = 3
Step-by-step explanation:
Given :-
u₂₀ = 100
u₂₅ = 115
To Find :-
u₁ and d
Solving :-
u₂₀ = u₁ + 19d = 100 -(1)
u₂₅ = u₁ + 24d = 115 -(2)
(2) - (1)
5d = 15
d = 3
u₁ + 19(3) = 100
u₁ + 57 = 100
u₁ = 43
Solution :-
a) u₁ = 43, d = 3

Answer:
C. (-1,6,1)
Step-by-step explanation:
Given the system of equation
6x−y+3z=−9 ...... 1
5x + 5y−5z = 20 ...... 2
3x−y+4z = −5 ...... 3
Reduce the equations to two variables with 2unknown
Multiply equation 3 by 2 and add to 1.
Equation 3×2; 6x−2y+8z = −10 ...... 4
Subtract 4 from 1
-y-(-2y)+3z-8z = -9-(-10)
-y+2y-5z = -9+10
y-5z = 1 ...... 5
Also multiply eqn 2 by 3 and 3 by 5
Equation 2×3; 15x+15y-15z= 60
Equation 3×5; 15x-5y+20z = -25
Subtract
15y+5y-15z-20z = 60+25
20y-35z = 85
Divide through by 5:
4y-7z = 17 ...... 6
...................................
Solve 5 and 6
y-5z = 1 ...... 5 × 4
4y-7z = 17 ...... 6 × 1
....................................
4y-20z = 4
4y-7z = 17
Subtract
-20z+7z = 4-17
-13z = -13
z = -13/-13
z = 1
Substitute z = 1 into equation 5 to get y:
From 5: y-5z = 1
y - 5(1) = 1
y-5 = 1
y = 1+5
y = 6
Substitute y = 6 and z = 1 into equation 3 to get x;
From 3: 3x−y+4z = −5
3x-6+4(1) = -5
3x -6+4 = -5
3x-2 = -5
3x = -5+2
3x = -3
x = -3/3
x = -1
Hence x = -1, y = 6 and z = 1

3. Jacki Marshall owes a balance of $5,000 on one credit card that charges 19 percent interest. She can pay off the balance in two years with monthly payments of $252.04. She has another credit card with a balance of $7,500 that charges 20 percent interest.
She can pay off the balance in two years with monthly payments of $381.72. Jacki owns a home valued at $150,000. She can get a home equity loan for $12,500 at 8 percent interest. Jacki can repay the loan in two years with monthly payments of $565.34. How much money will Jacki save if she takes out a home equityloan to pay off the credit card balances?
Answer:
1. $56,000
2. $3,695
3. $1,644.48
Step-by-step explanation:
1. Equity = valuation - mortgage
= $250,000 - $180,000
= $70,000
80% = 80/100 = 0.8
Therefore, 80% of the equity = 0.8 × $70,000
= $56,000
2. Total charges = jewelry charge + electronics charge
= $2,450 + $1,245
= $3,695
3.
First credit card:
Total payment = two years × monthly payments
= 2 × 12 × $252.04
= $6,048.96
Interest = total payment - balance
= $6,048.96 - $5,000
= $1,048.96
Second credit card:
Total payment = two years × monthly payments
= 2 × 12 × $381.72
= $9,161.28
Interest = total payment - balance
= $9,161.28 - $7,500
= $1,661.28
Home equity loan:
Total payment = two years × monthly payments
= 2 × 12 × $565.24
= $13,565.76
Interest = total payment - balance
= $13,565.76 - $12,500
= $1,065.76
Money saved = (total of interest from credit cards) - home equity loan interest
= ($1,048.96 + $1,661.28) - $1,065.76
= $1,644.48

Step-by-step explanation:
Answer:
20% of 50 = 10
Step-by-step explanation:
1. Convert the problem to an equation using the percentage formula: P% * X = Y
P is 20%, X is 50, so the equation is 20% * 50 = Y
2. Convert 20% to a decimal by removing the percent sign and dividing by 100: 20/100 = 0.2
3. Substitute 0.2 for 20% in the equation: 20% * 50 = Y becomes 0.2 * 50 = Y
4. Do the math: 0.2 * 50 = 10
5. Final answer: 20% of 50 is 10
