Question

A construction crew is lengthening a road. the road started with a length of 51 miles, and the crew is adding 4 miles to the road each day. let l represent the total length of the road (in miles), and let d represent the number of days the crew has worked. write an equation relating l to

d. then use this equation to find the total length of the road after the crew has worked 37 days.

Answer 1

L = total lengh, D = number of days

L = 4D + 51 <== ur equation

after 37 days...D = 37
L = 4(37) + 51
L = 148 + 51
L = 199 miles <==
