Answer:
13
Step-by-step explanation:
Do the divison! :D It's hard to write out on here, but you can find a lot of other online resources on how to do it, I reccomend Khan Academy.
Part A - 14 sections of fencing
Part B - 0.9165 the distance between each stake
1000 x .085 x 3 = 255
answer is <span>A: $255</span>
For this case, the first thing we must do is define variables.
We have then:
x: amount of time the assistant works
Y: amount of time the experienced person works
We then have the following system of equations:
x + y = 4
y = (1/2) x
Solving the system we have:
x = 8/3
y = 4/3
Answer:
It would take the roofer, working alone, to complete the same job about:
y = 4/3 hours
