The first one contains a typo and makes no sense 2nd: I bet you mean: 27^(x+5) = 9^(2x-1) then ... (3^3)^(x+5) = (3^2)^(2x-1) 3^(3x+15) = 3^(4x-2) 3x + 15 = 4x - 2 -x = -17 x = 17 3rd: 8(16^(x-1) = 4^(3x) (2^3)(2^(4x-4) = 2(6x) 2^(4x-1) = 2^(6x) 4x-1 = 6x -2x = 1 x = -1/2

The easy way to do this is p 3rd gas = nRT/V, then pA + pB + p3rd = Ptotal. You can do it the long way this way. n gas A = PV/RT. n gas B = PV/RT n third gas = 0.250 ntotal = nA + nB + n3rd. Then Ptotal = nRT/V You should get the same answer either way. I believe the answer is...

5th grade MATH!!!!!
No, it can only have one midpoint, because if it had two midpoints, then there would be two line segments! Also, if you add two midpoints, then thus creating another segment.
