Answer:
Dorsey = 4.8 hours
Campbell = 24 hours
Step-by-step explanation:
It takes "x" hours for Dorsey
So, it will take 5 times more for Campbell, so
It takes "5x" hours for Campbell
Rate is inverse of time, so rates are:
Dorsey: 1/x
Campbell: 1/5x
We know Rate * Time = Work
When together, it takes 4 hours to finish a work, so we can write:

Solving for x, we get the time of Dorsey:

Dorsey takes 4.8 hours alone
Campbell takes 4.8 * 5 = 24 hours alone
Answer:
The 3rd quadrant, where the x and y are both negative.
Answer:
The probability would be 5/15 or 1/3
Total = 7+3+5
= 15
yellow = 3
orange = 7
blue marbles = 5
B. The equation can become −2(4x − 1) = 12 by applying the addition property of equality because we have: <span>−2(4x − 1) − 7 = 5 / + 7 <=> -2(4x-1) = 12;</span>
Answer:
First we subtract 8,500 from the 18,040. What we get from that is 9540. Now we divide 9,540 by 3.8 and see what we get. What we get is 2510.52631579 which means it would take around 2510.52631579 days to pay 18,040. In total that rounds to 7 years. Rounding up by the way
