Answer:
-3x-7
Step-by-step explanation:
-3x and -6 aren't like terms, and neither are -3x and -1, so you leave -3x alone. You can combine -6 and -1. You simply add them as if they aren't negative and keep the negative sign. This results in -3x-7
Answer:
-63 gallons
Step-by-step explanation:
You don't know the original water amount, but it is asking for the change or the difference in the water volume so it doesn't even matter.
Since 7 gallons leak every hour and it is over 9 hours, you can multiply 9 by 7 to get 63 gallons.
I think it’s -3 if that is a choice
