Answer:
25h + 12
Step-by-step explanation:
The problem is:
21h - 10h + 14h + 16 - 9 + 5
You have to add like terms. You start by subtracting 21h - 10h which is equal to 11h
Then you do 11h + 14h which is 25h.
Next, you have to find the value of 16 - 9 + 5
16 - 9 = 7
7 + 5 = 12
So the final answer is 25h + 12
