Exercise 50 Page 569

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

x=4.4

Practice makes perfect
To solve the proportion, we will start by using the Cross Products Property.
x/10=22/50
50x=10 * 22
50x=220
From here, we will continue solving for x by using the Division Property of Equality.
50x=220
x=220/50
x=4.4
