Answer:he started with 20
Step-by-step explanation:
0.8(5x + 15) = 2.6 - x + 3 Use the Distributive Property
4x + 12 = 2.6 - x + 3 Combine like terms (2.6 and 3)
4x + 12 = 5.6 - x Add x to both sides
5x + 12 = 5.6 Subtract 12 from both sides
5x = -6.4 Divide both sides by 5
x = -1.28
First find the perimeter. Then take the depth of the pool and multiply it by the perimeter.
