(82 + 78 + 82 + 77 + x) / 5 = 80
319 + x = 80 * 5
319 + x = 400
x = 400 - 319
x = 81 <== she can get an 81 on it and still get a B
Answer: There are no solutions.
Step-by-step explanation: So the way you do this is by subtracting 9p from both sides, which gets you:
8 = -7
Since 8 is not equal to -7, there is no solution to this equation.
It would be (-2,8). they are asking for the midpoint between point A and point B

Algebra
The answer to this problem is to simply simplify it.
![\frac{1}{2} n + 3 < 5](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20n%20%2B%203%20%3C%205)
Subtract three from both sides.
![\frac{1}{2} n < 2](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20n%20%3C%202)
Multiply both sides by two.
![n < 4](https://tex.z-dn.net/?f=n%20%3C%204)
Meaning, n is anything below four.
