Question

A construction crew is lengthening a road. The crew is adding 6 miles to the road each week. The road originally measured 52 miles long. The crew's goal is given by 6x+52>130, where x is the number of weeks the crew works.

Answer 1

6x + 52 > 130

Subtract 52 from both sides:

6x > 78

Divide both sides by 6:

X > 78/6

X > 13
