Bethany finished her math homework at 4:20 p. M. She did 25 multiplication problems in all. If each problem took her 3 minutes to do, at what time did Bethany start her math homework?

Step-by-step explanation:

The number of problems completed by Bethany = 25

The time taken to complete 1 problem = 3 minutes

The time taken to complete 25 problems = 25 * 3 = 75 minutes

Bethany finished her math homework at 4:20 p.M.

So she started 75 minutes 4.20 PM, (i.e) 3.05 PM or

approx around 3 PM.

step-by-step explanation: divide by 2,

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
