4n+2
Step-by-step explanation:
- add all sides =9n+3
- 3n+2+2n-1=9n+3
- add liketerms 5n+1=9n+3

- ans hence is 4n+2
Answer
a decrease of 0.2 gallons per second
Explanation
The drain was open for 30 seconds.
The water that ran out for 30 seconds = 20 - 14
= 6 gallons
Rate of decrease = (change in gallons)/(time taken)
= 6/30
= 0.2
The rate of change in the amount of water remaining in the tub per second will be the same as the one that ran out since the outlet is the same.
So the correct answer from the choices is "a decrease of 0.2 gallons per second".

Hey there Shynee!
To do this equation, you have to flip the equation and do it on both sides.
k/0.32 = 2.2
Instead of division, multiply on both sides.
k/0.32 * 0.32 = 2.2 * 0.32
This isolates the variable
k = 0.704
and finds what x equals.
Check:
0.704/0.32 = 2.2
Correct.
I hope I helped!
