Step-by-step explanation:
Q24) It’s wrong because 7 - - 12 = 7 + 12 because two minus signs make a plus sign, 7 + 12 = 19
Q25) The answer is -3 - 9 because going deeper means negative

Answer:
c. 7h + 43 = 64
Step-by-step explanation:
If h is the hourly fee, then 7h is the fee for renting the equipment 7 hours. That added to the initial fee of $43 gives the total charge of $64.
7h + 43 = 64 . . . . . appropriately models the charges
___
The solution is h = (64 -43)/7 = 3. The hourly fee was $3.
