Answer: terri messed up at step 2 because she did the math rong so it turned to this (image)
[the dots are the points the line had to be in ]
1. 12x - 27x + 7x - 5 = 303
- 15x + 7x - 5 = 303
- 8x = 303 + 5
-8x = 308
x = - 38.5
2. 10x + 15 + 12x = 17
22x + 15 = 17
22x = 17 - 15
22x = 2
x = 0.0909090909
3.28x - 28 - 20 = 38
28x - 48 = 38
28x = 38 + 48
28x = 86
x = 3.07

Answer:
no solution
Step-by-step explanation:
Modular equation:
The modular of a function f(x)(|f(x)|) is the distance of f(x) to the origin.
In the case of a point, the modulus of the point is the distance to the origin.
If we have:
|f(x)| = a, it means that:
f(x) = a or f(x) = -a.
However
It is only true for non-negative values of a, since the modulus is a distance, which is a positive measure.
|–x| = –10
The modular is never a negative number, so it cannot be -10.
This means that there is no solution.
(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
