Exercise 52 Page 487

You can solve for the variable by using the Cross Products Property.

x=2.75

Practice makes perfect

To solve the proportion, we will start by using the Cross Products Property.

x-2/2=3/8

Cross multiply

8(x-2)=2 * 3

Multiply

8(x-2)=6

From here, we will continue solving for x by using the Distributive Property and the Properties of Equality.

8(x-2)=6

Distribute 8

8x-16=6

LHS+16=RHS+16

8x=22

.LHS /8.=.RHS /8.

x=22/8

Calculate quotient

x=2.75
