Answer:
15 and 5 hours.
Step-by-step explanation:
Call x the time taken by the first chap, and y the second.
Let's divide by 5 and play with the LHS of the first equation a bit:
we know how much x+y is ( first equation!) let's solve.
At this point it's easy to check that 
The manager’s likely error was forgetting to add the $2 back to the $18. Because $2 is roughly 11% of $18 for a markup you need to add the $2 back into the $18 for a total of $20.
Simple....
we know the formula you need to use is y=mx+b....
plug 'n chug....
3=3(1)+b
3=3+b
-3 -3
b=0
Thus.....y=3x
Thus, your answer.
I believe the answer would be c
Answer:Rewrite the expression substituting 5 for the x and simplify. Substitute for x and Simplify. 5(5). Answer. 25. -10. Expression a. 5x = b. -2x = C. X + 25 = d. 5x - 15 = e.
