Greyson rides his bike at a constant rate. In 30 minutes, Greyson can bike 7 miles. How far would you expect Greyson to ride in 105 minutes--I already got some of it done, 7 / 30 = 4 with a remainder so then 30 - 28 = 2. ALSO ( extra thing ) He can ride 21 miles in 90 minutes. Please help and thank you!

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4

step-by-step explanation:

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right

b, i believe, but not sure.
