Question

Write and solve a system of equations to solve the problem. At a film festival, Film A is 4 times as long as Film B. Together, the films are 160 minutes long. How long is each film?

Answer 1

Answer:

Each film is 20 min. long

Step-by-step explanation:

4x/2 = 160

(4x/4)/2 = (160/4)

      2x = 40

(2x/2) = (40/2)

     x = 20

Each film is 20 min. long
