Ashley and Liam both have playlists on their music apps.
The number of playlists on Ashley’s app can be represented by X.
The number of playlists on Liam’s app is 4 times the number of playlists on Ashley’s app.
The total number of playlists on both their apps is at least 45.
What is the solution set for x, representing the number of playlists on Ashley’s app?
(1 point)
Let's represent the number of playlists on Ashley's app as X.
According to the problem, the number of playlists on Liam's app is 4 times the number of playlists on Ashley's app. So, the number of playlists on Liam's app is 4X.
The total number of playlists on both apps is at least 45. This can be expressed as:
X + 4X >= 45
Combining like terms, we get:
5X >= 45
Dividing both sides of the inequality by 5, we get:
X >= 9
Therefore, the solution set for X, representing the number of playlists on Ashley's app, is X >= 9.
