The perimeter of a pool is 160 meters. the length of the pool is 20 meters more than its width. what is the length

To solve this question, write an equation where the width is x. x+x+(x+20)+(x+20) = 160. This equals 4x+40=160. Subtract 40 from both sides to get 4x=120. Divide both sides by 4 to get x=30. This means the width of the pool is 30 meters. Add 20 to the width (30) to get 50 meters. This means the length of the pool is 50 meters. I hope this helped!

true

step-by-step explanation:

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
