Exercise 43 Page 9

Relate the length and width using multiplication.

Equation: 9.5=1.9w
Width: 5 feet

Practice makes perfect

Let w represent the width of the flag. We are given that the length of the flag is 1.9 times as long as the width and that the length of the flag is 9.5 feet. 9.5=1.9w Let's solve the equation by dividing by 1.9 on both sides.

9.5=1.9w

DivEqn

.LHS /1.9.=.RHS /1.9.

5=w

RearrangeEqn

Rearrange equation

w=5

The solution w=5 means that the width of the flag is 5 feet.
