The ratio of 12th graders to 11th graders at a school is 5 to 8. If there are 440 11th
graders, how many. 12th graders are
there?

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20

−2

y=

−9
