Exercise 11 Page 607

Solve for the variable by using cross products.

10 or - 10

Practice makes perfect

To solve the proportion, we will start by using cross products. Then, we will continue solving for x by using the Properties of Equality.

x/12=50/6x

Cross multiply

x * 6x=12 * 50

Multiply

6x^2=600

.LHS /6.=.RHS /6.

x^2=100

sqrt(LHS)=sqrt(RHS)

x=± 10
