First you add 3 twice to both sides of the swimming pool
12 + 6 = 18
15 + 6 = 21
The perimeter is the sum of all sides therefore
18 + 18 + 21 + 21 = 78
The answer is A
I depends on how many balloons you are using
2500 divided by 100 is 25. If you multiply 25 times 3 you'll get 75. Repeat those steps (answers will be different each time) five times. You will get the answer.
Don't want to do that? OK! I'll do it for you!

Answer:

Step-by-step explanation:
To solve for y, you have to isolate it on one side of the equation.
<h3>12x+3y=9</h3>
<u>First, you have to subtract by 12x from both sides.</u>

<u>Solve.</u>

<u>Then, you divide by 3 from both sides.</u>

<u>Solve.</u>


Use the distributive property.

<h3>⇒A(B+C)=AB+AC</h3>
9-12x=3(3-4x)

<u>Divide the numbers from left to right.</u>
3/3=1
3-4x
<u>Then, rewrite the problem down.</u>

- <u>Therefore, the correct answer is y=3-4x.</u>
