Read and answer question 9 and 10 for 15 points

#9) They made 12 sandwiches.

#10) They used 36 ounces of cheese and 48 ounces of meat in an hour.

Step-by-step explanation:

Let's begin with number 9.

For each sandwich, you would use 3+4 ounces of meat+cheese. That would mean, each sandwich would use 7 ounces. And if in total, they used 84 ounces of meat+cheese you would do...

84/7 = 12

So that would mean they made 12 sandwiches.

And then for number 10, you would just multiply 12 by each of the amounts used in each sandwich.

Cheese: 3*12 = 36 ounces

Meat: 4*12 = 48 ounces

So your two answers would be...

#9) They made 12 sandwiches.

#10) They used 36 ounces of cheese and 48 ounces of meat in an hour.

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
