A -> Sherrie, b -> Carrie, c -> Mary.
a = 5b; a = 5(c - 5) = 5c - 25
b = c - 5
c = c
a + b + c = 68
5c - 25 + c - 5 + c = 68
7c - 30 = 68
7c = 98
c = 98/7
c = 14
Mary got 14 calls, Carrie got 5 less then Mary = 14 - 5 = 9, and Sherrie got 5 times as many as Carrie = 9 * 5 = 45.
This means that Carrie received D. 45 calls.
Th answer to number 1 is B. The answer to number 2 is C. The answer to number 3 is A. The answer to number 4 is the first graph {(1,80),(2,240),(3,720),(4,2160)}
Multiple of two has a 50 percent chance. greater than 15 is 25 percent. if both it's 10 percent
Assuming you meant the x2 as x squared, then:
(11x+4)(11x-4)
I don't know what the graph is counting by but here is an explanation:
Domain: (x value furthest left) ≤ x ≤ (x value furthest right)
Range: (y value furthest up) ≤ y ≤ (y value furthest down)
