We first assume that this gas is an ideal gas and we use the ideal gas equation to determine the answer. It is expressed as:
PV = nRT
Molar volume can be obtained from the equation by V/n.
V/n = RT/P
Therefore, the correct answer from the choices listed above is option A, <span>at 273 K and at 2.0 atm.</span>
3j + 2s = 79.38
3s + 2j = 75.12. 3s + 2j - 3s = -3s + 75.12. 2j/2 = -3/2s + 75.12/2.
j = -1.5s + 37.56
Then you can use substitution
3(-1.5s + 37.56) + 2s = 79.38
-4.5s + 112.68 + 2s = 79.38
-2.5s + 112.68 - 112.68 = 79.38 - 112.68
-2.5s = -33.30
-2.5s/-2.5 = -33.30/-2.5
s = 13.32
So s is 13.32 so you plug that back in and solve for j
3j + 26.64 = 79.38
3j + 26.64 - 26.64 = 79.38 - 26.64
3j = 52.74
3j/3 = 52.74/3
j = 17.58
So in Japan tickets average 17.58 and in Switzerland they average 13.32
I think 3x+12+x=180
because it is a supplementary angle and those equal 180
the sum of both sides on the straight line make 180
and if you were to solve it
it would be
= 42
