A mixture of orange paint contains 8 teaspoons of red paint and 12 teaspoons of yellow paint. To make the same shade of orange paint using 18 teaspoons of red paint, how much yellow paint would you need?

27 spoons of yellow paint

Step-by-step explanation:

Red paint : Yellow paint = 8 : 12

Let 'x' be the number of spoons of yellow paint.

8 : 12 :: 18 : x

Product of extremes = Product of means

8 * x = 12 * 18

     x = 3 *9

     x = 27 spoons

answer: 7 x 2/5 = 2.8 hours, is your answer. your welcome! : 3

step-by-step explanation: first work out how long it took to hose 1/7 of the lawn which is 2/5 hours. times that by 7 to get the whole lawn.

sorry i don't know the other answer. i didn't learn what a proportional relationship is.

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation
