Ok so find the median so put the numbers in order so 82,83,84,85,85,86,86,86,87,87,88,89,90 then start from both sides cross off from both dies at the same time 83,84,85,85,86,86,86,87,87,88,89
84,85,85,86,86,86,87,87,88
85,85,86,86,86,87,87
85,86,86,86,87
85,86,86,86
86,86
so... 86 is the answer. i know its long but its the whole work hope it helped.
3x = 12 - 6y....reduces to x = 4 - 2y...rearranged is x + 2y = 4
so now we have :
x + 2y = 3
x + 2y = 4
ok....I dont have to go any farther to know that this has no solution because ur equations have the same slope and different y int, this means ur lines are parallel and have no solution because they never cross each others path.
I think that this doesn't belong because every other option has a number after the variable (I forget the exact term for it but it's like +7, +4, and -1 for the rest of the options)
