It should equal to 180 so 180-157=23
<span>1) y varies directly with x, then we have: y = kx, k is the constant of variation
y = kx
14 = - 4k
k = 14/- 4, or - 7/2, or - 3.5
y = kx
y = - 3.5(- 6)
y=21
2) </span><span>201.6 is the right answer.see the procedure used in Q1.
3) K = y/x
= 9/12
= 3/4</span>
