Question

Colby is making a home video consisting of a 5-minute introduction followed by several short skits. Each skit is 9 minutes long. If Colby's video is 176 minutes long, how many skits are in his video?

Answer 1

Answer:

19

Step-by-step explanation:

If the number of skits is x we can write:

9x + 5 = 176

9x = 171

x = 19

Answer 2

176 - 5 = 171 : subtract the introduction
9x=171 : solve for x (9 min per skip)
x=19 : there are a total of 19 skits
