The construction of an 80-meter bridge was finished in 12 weeks. How much of the bridge was built on average each week?

6.6 meters a week

Step-by-step explanation:

This problem is quite simple

You take 80 and divide it by 12

80/12

which equals

6.6

answer: 2/4

step-by-step explanation:

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
