Can you help me on this

C) 9

Step-by-step explanation:

an hour = 60 minutes

to find 3/4 of an hour:

3/4 × 60 = 45 minutes left before he leaves for track practice

since each problem takes 1/12 of an hour:

1/12 × 60 = 5 minutes for each question spent

How many problems will he be able to finish?

45 minutes ÷ 5 minutes = 9 questions

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
