Answer:
Solving the equation [tex]15 = 3n + 6p[/tex] for variable n we get [tex]\mathbf{n=5-2p}[/tex]
Step-by-step explanation:
We need to solve the equation [tex]15 = 3n + 6p[/tex] for variable n
Solving:
[tex]15 = 3n + 6p[/tex]
Subtract both sides by 6p
[tex]15-6p = 3n +6p -6p\\15-6p=3n[/tex]
Switch sides of equality
[tex]3n=15-6p[/tex]
Divide both sides by 3
[tex]\frac{3n}{3} =\frac{15-6p}{3}\\n=\frac{3(5-2p)}{3}\\n=5-2p[/tex]
So, solving the equation [tex]15 = 3n + 6p[/tex] for variable n we get [tex]\mathbf{n=5-2p}[/tex]

If skim milk is 87% water, how many cups of skim milk contain 3.58 cups of water?
Answer:
4.11 cups of skim milk
Step-by-step explanation:
You can get the answer by knowing the value of a cup in milliliters first.
1 cup = 250 mlLet's convert 3.58 cups to ml by using the multiplication operation.
3.58 x 250 = 895 ml895 ml is 87% of skim milk.
Let's convert this into an equation. Let x be the amount of skim milk.
895 = 87% of x
895 = 0.87(x)
x = [tex]\frac{895}{0.87}[/tex]
x = 1,028.73 ml
Now that we know the amount of skim milk, let's convert it to cups.
1,028.73 ml ÷ 250 ml = 4.11 cups
Let's check.
4.11 x 87% = 3.5757 or 3.58 cups (It's correct).4.11 cups of skim milk contain 3.58 cups of water.
Given,
Skim milk contain water is 87% of water = 0.87
We have to find ,
Total no. of Cups of skim of milk 3.58 cups of water.
According to the question .
The value of a cup in milliliters first.
We know that ,
1 cup = 250 ml
Let's convert 3.58 cups to ml
3.58 x 250 = 895 ml
895 ml is 87% of skim milk.
Let's convert this into an equation. Let x be the amount of skim milk.
895 = 87% of x
895 = 0.87(x)
[tex]x = \frac{895}{0.87}[/tex]
x = 1,028.73 ml
To know the amount of skim milk, let's convert it to cups.
1,028.73 ml ÷ 250 ml = 4.11 cups

Ratio who signed other club:
4/5
Step-by-step explanation:
First find out ratio who signed up for art club
you have 16 out of 80
find the common factor: 16
16/16 = 1
80/16 = 5
so 1/5
other clubs is the rest so 5/5 - 1/5 = 4/5

Star A is about 3.4 X 10^18 miles from Earth. Star B is 6.8 X 10^16 miles from Earth. Star A is how many times as far from Earth as Star B?
Answer:
Concept: Numerical Analysis
Star A is 3.4 ×10 ^18Star B is 6.8 × 10^16Hence we want how much farther Star A is from Star B.Hence Star A/Star B = 50 times fartherRATE BRAINLISTAnswer:
1/50 as far
Step-by-step explanation:
6.8 x 10[tex]^{16}[/tex] ÷ 3.4 x 10[tex]^{18}[/tex]
Rules state that you divide numbers and subtract exponents
6.8/3.4 = 2
10[tex]^{16}[/tex] ÷ 10[tex]^{18}[/tex] = [tex]10^{-2}[/tex]
whenever exponent is negative, it gets turned into a fraction with 1 as the numerator and the exponent will become positive when placed in the denominator
10^-2 = 1/10^2 which is the same as 1/100
2 multiplied by 1/100 = 1/50

Bob invited 11 friends to his birthday party. He and his friends each ate two pieces of pizza. If they were eight slices in each whole pizza, how many whole pizzas do they fit in all?
Answer:
3 whole pizzas required.
Step-by-step explanation:
Given that:
Total number of friends invited by Bob = 11
Total number of people on the birthday party = 11 friends + 1 Bob himself = 12
Each friend has eaten = 2 pieces of pizza
Number of slices in one whole pizza = 8
To find:
Number of whole pizzas required at the birthday party.
Solution:
First of all, let us find the number of slices required for the birthday party.
Number of slices of pizza required for the birthday party = Number of slices eaten by each person multiplied by number of persons at party.
Number of slices of pizza required for the birthday party = 12 [tex]\times[/tex] 2 = 24
Now, let us divide the total number of slices with the number of slices in one whole pizza to find the total number of whole pizzas required for the party.
Number of whole pizzas required:
[tex]\dfrac{24}{8} = \bold{3}[/tex]

Answer:
D
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 7x - 10 ← is in slope- intercept form
with slope m = 7
Parallel lines have equal slopes, thus
m = 7 and point on line is T(- 3, 3 )
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line, then
y - 3 = 7(x - (- 3) ), that is
y - 3 = 7(x + 3) → D

Answer:
x = -1
Step-by-step explanation:
-2+3x=-(x+6) distrbute the negative
-2+3x=-x-6 combine liked terms (added x & 2 to each side)
+2 +x +x +2
4x = -4 isolate x (divide 4 from each side)
x = -1
Answer:
X=-1
Step-by-step explanation:
First, add 2 on both sides to eliminate -2 and to get 3x alone. Now you have the product of 3x=-x-4. Next, add x on both sides to isolate negative 4. Once, you have done this you get 4x=-4. Now you divide by 4 to get x alone. And you get the product x= -1.
If 3 tan A =cot A and A is an acute angle find angle A
Please, I need detailed explaination
Answer:
A is 30 degrees.
Step-by-step explanation:
cot A = 1/ tan A
Therefore 3 tan A = 1 / tan A
3 tan^2 A = 1
tan^2 A = 1/3
tan A = 1 /√3 is A is acute.
A = 30 degrees.
This is about trigonometric identities.
A = 30°
In trigonometric identities, we know that;Tan A = sin A/cos A
Cosec A = 1/sin A
Sec A = 1/cos A
Cot A = 1/tan A
Now, we are given;3 tan A = cot A
But we know from above that Cot A = 1/tan A
Thus;
3 tan A = 1/tan A
Rearranging to get;
(tan A)² = 1/3
tan A = √(1/3)
tan A = 1/√3
Now, from surd form of special angles, we know that;sin 30° = cos 60° = 1/2
sin 60° = cos 60° = (√3)/2
sin 45° = cos 45° = 1/√2
tan 30° = 1/√3
tan 60° = √3
tan 45° = 1
Comparing tan A = 1/√3 with the surd forms listed above, we can see that;A = 30°
A is said to be an acute angle which means it is less than 90° and so it is correct.
