One pound of grapes cost a 1.55.Which equation correctly shows a pair of equivalent ratios that can be used to find the cost of 3.5 pounds of grapes

x times 1.55

Step-by-step explanation:

3.5 times 1.55 = 5.325

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
