The average of all grades in his fencing class, including the upcoming one, (all grades summed up divided by the amount of grades) must be equal to 86 (percent), hence C is the right answer for 27.

So D is the right answer for 28.
Answer:
(-3,2) is the solution to the system of equation
Step-by-step explanation:
Here, we want to know the point that serves as a solution to the system of equation
We equate the y
-2x + 4 = -1/3x-1
Multiply through by 3
-6x + 12 = -x-3
-6x + x = -3-12
5x = 15
x = 15/5
x = 3
Substitute x into one of the y
y = -2(3) + 4
y = -6 + 4 = -2
So the solution is;
(3,-2)
