If y varies directly with x, write an equation for the direct variation. Then find each value,

if y = 6 when x =30, find y when x = 15

I think 3, because 15 is half of 30 and 3 is half of 6. Hope this helps

Just a guess Bc I’ve no idea what you’re talking abt, but 3. Would set 30/6 and 15/y cross multiply, solve for y and get y =3
