Answer:

33 gallons of water to begin with.
Step-by-step explanation:
So we essentially are given two coordinates: (6,87) and (21,222). To find an equation, we simply need to find the slope and y-intercept. We know it's a linear equation because it's a steady stream, meaning a constant slope.
The slope is:

So, the rate at which the stream flows is 9 gallons per minute.
Now, let's find the initial amount of water. To do this, we can use point-slope form. Pick either of the two points. I'm going to use (6,87).

So, there were 33 gallons of water in the tank to begin with.
Answer:
y=-1/2x-3
I hope this helps u :)
Step-by-step explanation:
Answer:
2.5 inches
Step-by-step explanation:
(1/4) x 10 = 2.5
or .25 x 10 = 2.5
C. X= 18
ex:
4x-7=7x-61
(They equal eachother)
you solve and get 18
Well if your having trouble you should stay after school and ask for help that's what I would do.
