Exercise 24 Page 547

You can solve the proportion by using the Cross Products Property.

5

Practice makes perfect

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

11/20=55/20x

Cross multiply

11(20x)=20(55)

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

11(20x)=20(55)

.LHS /20.=.RHS /20.

11x=55

.LHS /11.=.RHS /11.

x=5

Therefore, the solution for the given equation is x=5.
