For this case what you must do is add the number of hours to perform the different activities.
We have then:
14 person-hours of labor to break up to driveway and clear away the rubble.
8 person-hours of labor to pour and smooth concrete for the new driveway.
Adding both activities we have
14 + 8 = 22
answer
it takes to break up to driveway, clear away the rubble, pour the concrete, and smooth the concrete about 22 person-hours of labor
Answer:
Step-by-step explanation:
3x -8 = 2x + 5
x - 8 = 5
x = 13
3(13) - 8 + 2(13) + 5
39 - 8 + 26 + 5
31 + 31 = 62
