Answer 1

The number of playlists on Ashley's app is represented by X.
The number of playlists on Liam's app is 4 times the number of playlists on Ashley's app, so it is 4X.

The total number of playlists on both their apps is at least 45, so we have the inequality:

X + 4X ≥ 45

Combining like terms, we get:

5X ≥ 45

Dividing both sides by 5, we get:

X ≥ 9

Therefore, the solution set for x, representing the number of playlists on Ashley's app, is x ≥ 9. So the correct answer is:
X ≥ 9
