3 lines are intersecting. Line s is horizontal and contains points K and Y. Line m contains points J, K, W and intersects line s at K. Line n contains points Y and W and intersects line s at Y and intersects line m at W. Point P is above and right of the intersecting lines. Point X is below and left of the intersecting lines. The three collinear points on line m are

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:

b. 2 and 4

step-by-step explanation:

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)
