The Unruly Queens chess club is hosting a tournament, and each club member bringing something to eat or drink. Kristen decides to bring oatmeal raisin cookies from her favorite
bakery
There is a proportional relationship between the number of oatmeal raisin cookies Kristen
buys, x, and their total cost (in dollars), y.

WhT is the constant of proportionality? Right a whole number or decimal

location: point 0

step-by-step explanation:

well, -8 to 10 on a number line is 18 spaces.

1/9 of 18 is 2.

so, 4/9 of 18 must be 8.

8 spaces from -8 (a) is 0.

so, 4/9 of the way from -8 to 10 is 0!

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:

3 1/3 x 2 3/5 = 8 2/3

step-by-step explanation:

just multiply the first number by the second number to get your answer.
