Q:

A construction crew is lengthening a road. The road started with a length of 51 miles, and the crew is adding 2 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 33 days.

Accepted Solution

A:
Answer:Total length after 33 days will be 117 miles Step-by-step explanation:A construction crew is lengthening a road. The road started with a length of 51 miles.Average addition of the road is = 2 miles per day Let the number of days crew has worked are D and length of the road is L, then length of the road can represented by the equation L = 2D + 51If the number of days worked by the crew is = 33 days Then total length of the road will be L = 2Γ—33 + 51 L = 66 + 51 L = 117 milesTotal length of the road after 33 days of the construction will be 117 miles.
