85C - 170A = 306 ---------- (1)
255 + 85B = 714 ------------(2)
(1) + (2):
85C + 85A + 85B = 1020
Divide by 85 through:
A + B + C = 12
The total of A, B ad C is 12.

Find average :
-------------------------------------------------------------
The average of A, B and C is 12 ÷ 3 = 4
-------------------------------------------------------------
Answer: The average of A, B and C is 4.

Answer:
the slope is 11 and the y intercept is 6 m=11 b=6
Answer:
Therefore, Δx=5/n, when have n intervals.
Step-by-step explanation:
From exercise we have interval [0,5]. So the length of the given interval is 5-0=5. Since all intervals [x0,x1],[x1,x2],…,[xn−1,xn] are equal in width.
We know that their width is Δx. We conclude that width of each subinterval Δx in terms of the number of subintervals n is equal 5/n.
Therefore, Δx=5/n, when have n intervals.
Answer:
We have the system:
y > 2*x
y > 3
Now, let's find the limits:
taking y > 3, we can see the limit y = 3.
Now we replace it in the first inequality:
3 > 2*x
3/2 > x.
Then we have that:
y > 3
x < 3/2
Those two inequalities define our system.
So any ordered pair where x is smaller than 3/2 and y is larger than 3, is a solution.
or example:
(1, 3.5) is a solution.
