Answer:
1: 23.85
2: 83%
3: 44
Step-by-step explanation:
1 - do 53x0.45 (23.85)
2 - Divide 20 by 24, which you get 0.833333333 and move the decimal 2x to the right. You get 83.3333333, but round. So 83%
3 - do 80x0.55 (44)
F(x) = 4x
so f(-2) = 4*-2 = -8
and
g((f(-2)) = g(-8) = -16-1 = -17
Its A
B ) 75 Miles per hour
75 + 64(10) = 640 + 75 = 715
715 ÷ 11 ( how many drivers ) = 65
