a barrel contains 183 gallon of gas, and it is being drained at  a constant rate of 9 gallons a minute.  Write equation that models the numberes of gallon, g, after t minutes.  The equation that model the given situation is ??

parthkohli · Answer

The original amount is 183, and it is decreasing at 9 per minute.

anonymous · Answer

correct I thought that you would divide 183/9 to get the situation

parthkohli · Answer

In 1 minute, the barrel would have decreased by $9 \times 1$ gallons.
In 2, would've decreased by $9 \times 2$ gallons.

parthkohli · Answer

In 1 minute, the barrel would have contained $\rm 183 - (9 \times 1)$ gallons.
In 2 minutes, the barrel would have contained $\rm 183 - (9 \times 2)$ gallons.

anonymous · Answer

so the first one would be 183-9=174
and the second one is 183-18=165
do I keep going

parthkohli · Answer

But you have to model an equation. What would it be?

anonymous · Answer

183-(9*1)

anonymous · Answer

right

anonymous · Answer

can someone please help me do not understand how to do equation

parthkohli · Answer

Hmm, you have to model an equation which represents the number of gallons left in 't' minutes.

anonymous · Answer

I am sorry I do not understand
so you are telling me if I have 183 gallons and 9 are being taking away every minute so would it be 183-(9*x)
