A number h added to −3 is at most 3.4.

-3 + h ≤ 3.4

Step-by-step explanation:

Let the unknown number be h. If A number h added to −3, this is expressed as;

-3 + h

Since the result is at most 3.4, it means that it cannot be greater than 3.4, hence the best inequality sign to use is a less than or equal to sign ≤. The required expression will be;

-3 + h ≤ 3.4
