The lines graphed below are parallel. the slope of the red line is -. what is the slope of the green line?

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:

6x = 48

i hope this . 6 cards each and a total of $48. dvide each side by 6 and you will have your answer.
