3 gallons are left.
If you divide 384 by 32, the answer is 12.
15-12=3
<u>Part</u><u> </u><u>1</u>
Subtracting 5 from both sides yields

<u>Part</u><u> </u><u>2</u>
When the output, f(x) is 2, we can substitute that in to obtain

Answer:
I would need to be able to see the expressions available.
Step-by-step explanation:
32.the answer is 2c+0
this is all I can do for now
X = first film....y = second film
x + y = 132
x = 2y - 3
2y - 3 + y = 132
3y - 3 = 132
3y = 132 + 3
3y = 135
y = 135/3
y = 45......so the 2nd film lasted 45 minutes
x = 2y - 3
x = 2(45) - 3
x = 90 - 3
x = 87 <=== the first film lasted 87 minutes
