Plz help I’ve been stuck on this question

A) 11.29

Step-by-step explanation:

First you want to add 5.25 to 5.25 to 5.25 to get how much she put in. That equals 15.75. Now we subtract 4.46 from that and we will get 11.29. I hope this helps.

The variable is the number of hours Adi studied, the operation is addition, and the constant is 3. You can write the expression as h + 3 or 3 + h. To evaluate, substitute 8 in for the variable, h, and simplify. 8 plus 3 is 11. So Adi studied for 11 hours.

hope it helped 1
