8.) Henry's MP3 player has 512MB of memory. He has already downloaded 287MB and will
continue to download m more megabytes.
Write and solve an inequality that shows how
many more megabytes he can download.

Henry can download at most 225 MB more.

Step-by-step explanation:

The capacity of Henry's MP3 player is 512MB. He has downloaded 287MB and will continue to download m more megabytes.

Since the capacity of the player is 512MB. The used memory plus 287MB cannot be greater than 512MB, thus the inequality that shows how many more megabytes he can download are:

m + 287 ≤ 512

Solving:

m  ≤ 512 - 287

m  ≤ 225

Henry can download at most 225 MB more.

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get
