Jack, sally and joe all work in a bookstore. jack sold 126 books. joe sold 1/2 as many books as many books as jack, and sally solly sold 1/3 as many books as joe. how many books did sally sell?

the number of books that Sally sold is 21

Step-by-step explanation:

Jack sold 126 books. Joe sold 1/2 as many books as many books as jack. This means that the number of books that Joe sold would be

1/2 × 126 = 63

Sally sold 1/3 as many books as joe. This means that the number of books that Sally sold would be

1/3 × 63 = 21 books.

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
