I have 9.25 already attached to my email My email program will not send a message above 20 mb write an inequality that shows the number of additional mb that I need to add to my email

Let x represent the additional megabytes (mb) that you need to add to your email.

The total size of the email, including the 9.25 mb already attached, is given by 9.25 + x.
Since the email program will not send a message above 20 mb, the inequality representing this would be:
9.25 + x ≤ 20

Therefore, the inequality representing the number of additional mb that you need to add to your email is 9.25 + x ≤ 20.
