Ateam won 3 of their first 10 games. if they win the next n games, they will have won 50% of their games. what does n equal?

i believe it's a.

i'm not sure on this one, most likely correct.

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)

hope that .
