Jorge is building a train set for his cousin. He has a piece of plywood that measures 49.5 inches in length, and he needs 2.25 inch pieces for the tracks. How many pieces can he cut from his piece of plywood?

22 pieces

Step-by-step explanation:

You have to divide 49.5 ÷ 2.25

49.5÷2.25= 22

Jorge can cut 22 pieces of plywood for the tracks.

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:

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1
