Exercise 51 Page 569

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

x ≈ 52.3

Practice makes perfect

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

20.2/88=12/x

Cross multiply

20.2x=88(12)

Multiply

20.2x=1056

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

20.2x=1056

.LHS /20.2.=.RHS /20.2.

x=1056/20.2

Calculate quotient

x ≈ 52.3
