Follow the steps to finish solving the equation -3x +18 = 7x 1. Add 3x to both sides to isolate the variable term.

2. Divide both sides by 10.

x=

The length of a rectangle is x times the square root of 100. the width is one-half y more than three-halves x. given that the area of the rectangle is 125 cm2, which equation could represent the rectangle in terms of x and y? a) 5xy − 15x = 125 b) 5xy + 15x = 125 c) 15x2 − 5xy = 125 d) 15x2 + 5xy = 125
