so its D

Answer 3

righ?

Answer 4

yes

Answer 5

let answer another question alright ?

Answer 18

i got a

Answer 19

yes

Answer 20

the last 1

Answer 21

Solve the system, using substitution. One point for correct steps, one point for correct ordered pair.
x = 4y and 2x + 3y = 44

Answer 22

put x=4y in the eqn 2x + 3y =44 to get y .. from that y get x
