-8.8
Step-by-step explanation:
We begin by simplifying the parenthesis through multiplication. Parenthesis is a structure which signals multiplication happening.

We now begin combining like terms across the equal sign by performing the inverse or doing the opposite. Move first the 8.11 by subtracting it from both sides.

Now, move 4.3v across by subtracting it from both sides.


Finally, we divide both sides by the coefficient of v.

1/2 <u>or</u> 0.5 <u>or</u> 50%
Step-by-step explanation:
3 + 3 = 6

sum them then divide by 4
(32+31+37+44)=144
divide by 4
144/4=36
answer is C
