The problem I need help on is "Ali has $48 to spend on lunch with his friends. Each sandwich costs $3 and each coffee costs $2. Write an equation to represent the amount of money Ali has."

4

step-by-step explanation:

6 (donuts) divided by 3 is 2.

so 2/3 means 2 times 2, which is 4/6.

you get two and your friend gets four.

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

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
