Step-by-step explanation:
Answer:
1. 3/4
2.-3/2
Step-by-step explanation:
For the first problem, distribute the 2(6-2x) and 2(5+x) to simplify the equation. This means, multiply what's inside the parentheses by 2. The simplified version of the equation is: 12-4x-2x=10+2x-4.
Once you have distributed, then combine like terms and solve for x.
You do the same thing for the second problem.
how do you graph this
y-2x=0
y=4x+3
Answer:
Step-by-step explanation:
those are 2 lines, and to graph them find 2 points for each to draw a line trough them
line 1
y-2x=0 so y=2x
pick any value for x
(x=1, y=2*1=2), (x=3, y=2*3=6)
Draw a line trough points (1,2) and (3,6)
line 2
y=4x+3
(x=1, y=4*1+3=7), (x= -1, y= 4(-1)+3= -1)
Draw a line trough points (1,7) and (-1, -1)
Which number represents 50% of 74?
35
37
38
39
Answer: 37!!!
Step-by-step explanation:
1. 50% equals .5 in decimal form.
When converting a percentage to decimal, divide by 100 or move the decimal point to the left twice.
2. The word of means multiply so we multiply .5 by 74.
3. We get 37!

explain in your own words one way you could turn 9/25 into a decimal.
YOU HAAVE TO EXPLAIN
Answer
Step-by-step explanation:
If 25 goes into 100 four times, then multiple 9 x 4 and then make it into a precent. 9 x 4 = 36, would equal .36
Answer:
To turn 9/25 into a decimal, you could turn the denominator to 100. In order to do this, you can multiply both the numerator and denominator by 4. 9/25 x 4/4 = 36/100. 36/100 converted into a decimal is 0.36.

Graph the following system of inequalities.
Answer:
X i think
Step-by-step explanation:
A container is filled with 100 grams of bird feed that is 80% seed. Tom and Sally want to mix the 100 grams with bird feed that is 5% seed to get a mixture that is 40% seed. Tom wants to add 114 grams of the 5% seed, and Sally wants to add 115 grams of the 5% seed mix. What will be the percent of seed if Tom adds 114 grams?
Answer:
Initially, we had:
100 grams of a mixture that is 80% seed, (or 0.8 in decimal form)
This means that the quotient between the mass of seeds and the total mass of the mixture is equal to 0.8
Then the mass of seeds, x, can be calculated as:
x/100g = 0.8
x = 0.8*100g
x = 80g
We also have another mixture, that is 5% seed (or 0.05 in decimal form)
This means that in X grams of this mixture, there will be y grams of seeds, such that:
y/X = 0.05
y = 0.05*X grams
Now, we want to create a mixture that is 40% seeds (or 0.4 in decimal form).
Let's do this.
If we add X grams of the 5% mixture, the total mass will be:
M = 100g + X.
The total mass of seeds will be:
m = 80g + X*0.05
and we want that the quotient between the mass of seeds and the total mass to be exactly 0.4
m/M = 0.4
(80g + X*0.05)/(100g + X) = 0.4
Let's solve this for X.
(80g + X*0.05) = 0.4*(100g + X)
80g + X*0.05 = 40g + X*0.4
80g - 40g = X*0.4 - X*0.05
40g = X*0.35
40g/0.35 = X = 114.2g
If we want the mixture to be exactly 40% seeds, we need to add 114.2g of the 5% mixture. (We already can see that Tom is closer to the exact result than Sally)
If we add 114g, like Tom wants, we will have:
M = 100g + 114g = 214g
m = 80g + 0.05*114g = 85.7g
m/M = 85.7g/214g = 0.4005
This is a really good aproximation, if we write this in percentage form this would be:
0.4005*100% = 40.05%

Answer:
[tex]Area =\frac{10x + 15}{2}[/tex] in both cases
Step-by-step explanation:
See attachment for complete question.
From the attachment, we have the following given parameters
Green Section: Dimension: x by 2
Orange Section: Dimension: 2 by [tex]1\frac{1}{2}[/tex]
Purple Section: Dimension: 3 by (x + [tex]1\frac{1}{2}[/tex])
Solving (a): Area of the flag as a sum of each section
We simply calculate the area of each section.
[tex]Area = Length * Width[/tex]
For the green section;
[tex]Area = x * 2[/tex]
[tex]Area = 2x[/tex]
For the orange section
[tex]Area = 2 * 1\frac{1}{2}[/tex]
[tex]Area = 3[/tex]
For the purple section
[tex]Area = 3 * (x + 1\frac{1}{2})[/tex]
[tex]Area = 3 * (x + \frac{3}{2})[/tex]
[tex]Area = 3x + \frac{9}{2}[/tex]
Total Area = Sum of the above areas
[tex]Area = 2x + 3 + 3x + \frac{9}{2}[/tex]
Collect Like Terms
[tex]Area = 2x + 3x+ 3 + \frac{9}{2}\\[/tex]
[tex]Area = 5x+ \frac{6+9}{2}[/tex]
[tex]Area = 5x+ \frac{15}{2}[/tex]
[tex]Area =\frac{10x + 15}{2}[/tex]
Solving (b): Area of the flag as a product
From the attachment,
[tex]Length = 2 + 3[/tex]
[tex]Length = 5[/tex]
[tex]Width = x + 1\frac{1}{2}[/tex]
[tex]Area = Length * Width[/tex]
[tex]Area = 5(x + 1\frac{1}{2})[/tex]
[tex]Area = 5(x + \frac{3}{2})[/tex]
[tex]Area = 5x + \frac{15}{2}[/tex]
Take LCM
[tex]Area = \frac{10x + 15}{2}[/tex]

Use 3.14 for it, and do not round your answer. Be sure to include the correct unit in your answer.
Answer:
[tex]C=32(3.14)=100.48\text{ meters}[/tex]
Step-by-step explanation:
We know that the circle has a diameter of 32 meters.
And we want to find its circumference.
The circumference of a circle is given by the formula:
[tex]C=\pi d[/tex]
Where d is the diameter.
So, we will substitute 32 for d and we will use 3.14 for π. Hence, our circumference will be:
[tex]C=32(3.14)=100.48\text{ meters}[/tex]
Answer:
100.48 m
Step-by-step explanation:
C=2(3.14)r
C=2(3.14)(16)
C= 100.48 m

Charlie can spend up to 10$ on lunch. He wants to buy a turkey sandwich, a bottle of soda,
and x pounds of macaroni. If a turkey sandwich cost $3.75, a bottle of soda cost $2.25, and
macaroni costs $2 per pound, find the range of pounds of macaroni that Charlie can buy.
Answer:
he can buy 2 pounds of macaroni
Step-by-step explanation:
first you add up the 3.75 and the 2.25 from the turkey and the soda. it ranges to 6 dollars. then if each macaroni pound is 2 you will be able to buy 2 pounds from the 4 dollars you have lefy
Answer:
Charlie can buy 1 or 2 pounds of macaroni
Step-by-step explanation
If we add up the cost of the turkey sandwich and the soda, we get $6.00. Charlie has $10.00 to spend, so when he buys the sandwich and soda, he will have $4.00 left to spend. If the macaroni is $2.00 per pound, then Charlie can buy 1 or 2 pounds of macaroni.

A field is in the shape of a Rectangle. The width
of the rectangle is x yards. The length of the
rectangle is 3 more than the width. Write an
expression for the perimeter of the field.
Answer:
4x+6
Step-by-step explanation:
The perimeter of the field can be obtained by calculating the distance around the field.
in this case, we know that the shape of the field is a rectangle.
The perimeter of a rectangle can be obtained by using the formula
[tex]2(l+b)[/tex]
The width of the rectangle is given as x yards
The length of the rectangle is given as x +3 yards
Therefore, an expression to determine the perimeter of the rectangle can be given as
[tex]2(x+3+x)\\=2(2x+3)\\=4x+6[/tex]
