Answer:
[(1/12)(5/5) + (1/20)(3/3)](x hours) = 1
(5/60 + 3/60)x = 1
(8/60)x = 1 we can reduce 8/60 by dividing out a 4
(2/15)x = 1 x both sides by 15/2
x = 15/2
x = 7 1/2 or 7.5 hours
I hope it helps you get it right
Answer:
The volume(V) of gas will increase when the pressure of the gas decreases assuming all the other variables are held constant.
