Answer:
C. -1
Step-by-step explanation:
I calculated it logically
4 cups per quarter
4 x 7 = 28
28 kids can have a cup of hot chocolate.
120+24 divided by 8=
144 divided by 8= 18 because 18 times 8 equals 144
So,
First you have to distribute the numbers outside of the parentheses (you multiply them with the numbers inside of the parentheses
-18+(-9a) + 8a +36=11
Then collect like terms
18-1a =11
-18 -18
---------------------
-1a=-7
Divide both sides by -1
a=7
The answer would be 8 dogs.
