Does it have extra information or missing information

I would say it has extra information. All you need to really know is that she's going to type 500 words. The info about writing the essay in 5 hours and how many pages is not needed. To solve, I would divide 500 by 60, which is 8.3 repeating, or just 8.3, so it'd take 8.3 minutes to type it up. Please correct me if I'm wrong!

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=
