Lets say, for ease, that the vat can hold a total of 70 gallons (or whatever you would like to use.) Use whatever number you want, I just picked this because it gives us a lot of clean numbers.
Now, if the inlet can fill it in 7 hours, that means that it is adding 10 gallons per hour. (70 gal/7 hours = 10 gal/hr)
For the outlet, use the same process, and you find that it drains the vat at 7 gallons per hour.
So, if you subtract the outlet from the inlet, you get 10 - 7 = 3 gallons per hour added.
Now just divide the size of the vat by that number, and you find your answer.
70 gallons / 3 gallons per hour = 23 1/3 hours.
Given a number w, six more than that number is 
. If you want this result to be 2, you have
Subtract 6 from both sides to get
This will give us
That is the second option.
Please mark me as brainliest.

Step-by-step explanation:
when its 2 negative they turn to a positive
Hello there.
The sequence is being divided by ten
51/10= 5.1
5.1/10 = 0.51
0.51/10 = 0.051,
and so on.
You can also reverse the following sequence and multiply it by ten.
