7-64.

Write and solve an equation for the situation below. Define any variables and write your solution as a sentence.

Jennifer has a total of four and a half hours to spend on the beach swimming and playing volleyball. The time she spends playing volleyball will be twice the amount of time she spends swimming. How long will she do each activity? Homework Help ✎

Write an equation in which *x* represents the time spent swimming and 2*x* represents the time spent playing volleyball.*x* + 2*x* = 4.5

Solve for the time spent swimming, *x*, then double that number to find the time spent playing volleyball.

3*x* = 4.5*x* = 1.5

1.5 hours spent swimming and 3 hours spent playing volleyball.
