Answer:
The correct option is (c).
Step-by-step explanation:
The combined formula is given by :
...(1)
h is height
V is volume

Answer:
3
Step-by-step explanation
cause there are three rooms that need to be painted
3/5(30x - 15) = 72
18x - 9 = 72 <==== this is one
3(6x - 3) = 72 <== this is one
18x = 81 <== this is one
x = 81/18
x = 4.5 <== this is one
Here, the equation would be: 50t + 60t = 247.5
They will take same time, as they started their journey at a time.
Value of t, = 247.5/110 = 2.25
So, Armand traveled = 2.25 * 50 = 112.5
Jill traveled = 2.25 * 60 = 135
According to all of that information, Your Answers would be Option B, C & E
Hope this helps!
