Exercise 90 Page 177

Use the Multiplication Property of Equality to eliminate the division.

20

Practice makes perfect

To solve the equation, we have to isolate v on one side. Using the Multiplication Property of Equality, we will multiply both sides of the equation by 2. This will eliminate the denominator of the fraction and isolate v.

10=v/2

LHS * 2=RHS* 2

10(2)=v/2(2)

a/2* 2 = a

20=v

Rearrange equation

v=20

The correct solution is v=20.
