You work on a concrete crew starting a construction project. Once the pouring begins, it must continue non-stop until it is completed. Your crew will work an 8-hour shift along with two other crews. The total project requires 175,000 yards of concrete. Your supervisor estimates that each crew will pour around 1200 yards per hour. How many consecutive days should you plan to work on this project? A3

B.6

C. 18

D. 27

i would say the answer is d

Step-by-step explanation:

the answer is really -0.7

Step-by-step explanation:

 -9.0 + 8.3

-9.0

+8.3

0-3 is 7 because you have to take away the zero and replace it with ten

you borrowed that ten from the 9 so the nine is now a negative eight.

now you subract and it becomes a zero. the answer's sign is that of the bigger number so, we would take the negative sign from the nine since it is bigger than eight. so the answer is -0.7.
