A point is [8,5] and b is the point [-4,1] determine the coordinates of the midpoint of ab

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

10000

step-by-step explanation: divide by 2,

i belive those are the ones that are under 90 degreese.
