Answer: 18/5 hours, or 3.6 hours
=================================================
Work Shown:
x = amount of time it takes Blake to do the job by himself
y = amount of time it takes Ned to do the job by himself
z = time it takes if they worked together
In this case,
x = 9 and y = 6
Use those values to find z.
-5(3m + 6) = -3(4m - 2)
-15m - 30 = -12m + 6
-30 = -12m + 6 + 15m
-30 = 3m + 6
-30 - 6 = 3m
-36 = 3m
-36/3 = m
-12 = m
hope this helps, God bless!
Let the length of the shortest side be x, then the length of the second side is x + 4 and the length of the third side is 2x - 4.
Then, x + x + 4 + 2x - 4 = 52
4x = 52
x = 52/4 = 13
Therefore, the lengths of the sides of the triangle are: x = 13, x + 4 = 13 + 4 = 17 and 2x - 4 = 2(13) - 4 = 26 - 4 = 22.
i.e. 13, 17, 22
9:252
Im sure the 252 means the days.
