If you go through the multiplication table of 3, you can pick out the ones between 5 and 31:
6, 9, 12, 15, 18, 21, 24, 27, 30
Which is 9 numbers. I hope this helps!
W=4x+9y
-9y=-w+4x
9y=w-4x
y=(w-4x)/9
Hope this helps :)
What you have is a valid ratio in theory, but it might be easier to understand if it were simplified to integers:
78:13:65
It also depends on what your teacher is asking of you.
The question is asking to calculate how fast is the water level rising when the water is 9 inches deep and base on the said question or problem, and in my own understanding and computation about the said problem, the speed of the rising of the water level is 24/63 feet per minute. I hope this would help
