Juan's model locomotive is 7 5/8 in. long. His coal car is 6 1/4 in. long. When hooked together, there is a 7/8-inch
space between cars. What is the total length when the
two cars are hooked together?
in.

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

2

x+10
