Answer:
N
Step-by-step explanation:
I am pretty sure the answer is b
Let x = Class A
Let y = Class B
Let z = Class C
Equations from problem:
x - 160 = y
2/3x = z
y + 92 = z
Solving through substitution:
2/3x = y + 92
2/3x = (x - 160) + 92
2/3x = x - 68
-1/3x = -68
3(-1/3x) = 3(-68)
-x = -204
x = 204
Now substitute x in the first equation to get y:
204 - 160 = y
44 = y
44 = Class B
There are 44 folded paper cranes in Class B.
300 x 0.65 = 195.
65% of 300 is 195.
The answer would be B because the average rate of change formula calculates slope of lines, or a curve on a given range.it is defines as the ratio of the difference in the function (f/x) as it changes from "a" to "b" and the difference between "a" and "b" so ya answer is B
