ANSWER
C. 7
EXPLANATION
We want to evaluate
![2 - ( - 8) + ( - 3)](https://tex.z-dn.net/?f=2%20-%20%28%20%20-%208%29%20%2B%20%28%20-%203%29%20)
We use the order of operations PEDMAS.
Dealing with the parenthesis first,we have
![2 - - 8+- 3](https://tex.z-dn.net/?f=2%20%20-%20%20-%208%2B-%203)
Note that:
![- - = +](https://tex.z-dn.net/?f=%20-%20%20%20%20-%20%20%3D%20%20%2B%20)
and
![- + = -](https://tex.z-dn.net/?f=%20-%20%20%2B%20%20%3D%20%20-%20)
Our expression now becomes:
![2 + 8 - 3](https://tex.z-dn.net/?f=2%20%2B%208%20-%203)
Next, we add to get:
![10 - 3](https://tex.z-dn.net/?f=10%20-%203)
We finally subtract to get,
![7](https://tex.z-dn.net/?f=7)
The correct answer is C
180-93.5=86.5
x=86.5:2=43.25
