Volume of water in the tank:
Differentiate both sides with respect to time <em>t</em> :
<em>V</em> changes at a rate of 2000 cc/min (cubic cm per minute); use this to solve for d<em>h</em>/d<em>t</em> :
(The question asks how the height changes at the exact moment the height is 50 cm, but this info is a red herring because the rate of change is constant.)
Answer:
XA = 9
AY = 9
XY = 18
Step-by-step explanation:

The given expression is
First, we use the distributive property to get rid of the parenthesis.
Then, we reduce like terms. -2x and 3x are like terms, also 7 and 10 are like terms.
<h2>Therefore, the simplest form of the given expression is <em>x + 17</em>.</h2>
The question asks you to find the total amount of rain after each hour, and has given you the ratio of 1.5 cm of rain in an hour. Therefore to find the rest, you’ll need to multiply the number of hours by the amount of rain in an hour:
2hrs - 3 cm
3hrs - 4.5 cm
4hrs - 6 cm
5hrs - 7.5 cm
I hope this helps and that I’m right! Good luck!! :)
X=popcorn
x - 3.50=drink
2x+ 4(x-3.50)=32.50
2x+4x-14=32.50
solve for x
