Answer:

Choice C is correct.

Step-by-step explanation:

We have given an equation :

-5(a+3)=-55

We have to solve it for a.

-5(a+3)= -55

-5a-15= -55

Adding 15 on both sides of equation we get,

-5a =  -55+15

Multiplying 1/-5 on both sides we get,

-5a = -40

a = -40/ -5

a = 8 is the answer.
