explanation: Sorry i couldn’t finish and i hope these are correct! I’m not that good at math but good luck
G(x)=X+11 where y is the total temperature after it rose & x is the temperature when Iko woke up. F(x)= g(x) -14 . Where f(x) is the temperature after it dropped 14 and g(x) is the temperature it was by lunch time.
X 0 y was 30
at x 12 y is about 55
12-0 = 12
55-30 = 25
25/12 = 2.08 inches per year average
so answer should be D
A is 40
B is 50
C is 115
Explanation, A is the same as the opposite, A + B + 90 = 180, and C + 65 = 180
