Step-by-step explanation:
10 workers work 2 hrs a day for 5 days, so the work content is 10*5*2=100 manhours.

The answer is 10 days.
Answer: D. (8, 4)
Step-by-step explanation:
Answer:
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
10*y-(80)=0
Pull out like factors :
10y - 80 = 10 • (y - 8)
Solve : 10 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solve : y-8 = 0
Add 8 to both sides of the equation :
y = 8
Answer:
graph C
