Jacob rode his bicycle 2 miles per week more than Lesley per week.  

Step-by-step explanation:

We are given the following in the questions:

Jacob rode his bicycle 144 miles in 9 weeks.

Number of miles rode in 1 week by Jacob =

Lesley rode her bicycle 84 miles in 6 weeks.

Number of miles rode in 1 week by Lesley =

Thus, Jacob rode his bicycle more than Lesley by

Thus, Jacob rode his bicycle 2 miles per week more than Lesley per week.

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
