Answer:
l=48, w=20
Step-by-step explanation:
Let the width of the pool be w feet, then the length will be:

The area of the pool is 960 square feet.
This means that:

Expand and rewrite in standard form to get:




Factor to get:


We discard the negative value because magnitude is positive.
This means

15+8x=2x+7-5x
Subtract 8x from both sides.
15=2x+7-5x-8x
Combine like terms.
15=-11x+7
Subtract 7 from both sides.
8=-11x
Divide -11 from both sides.
.73=x
Your answer is .72
Answer:
-7 and 21
Step-by-step explanation:
y-2y=7 (sub x=7 to the equation)
-y=7
y=-7 (not sure of its correct)
if y=-7,
x-2(-7)=7 (sub y=-7 into equation)
x-14=7
X=7+14
X=21
Answer:
Step-by-step explanation:
You are going to have to divide 1433 by 67 and you see how much money equals one training sesion. Then you do 79 training sessions by how much money is equal to one training session
