p varies directly as q. When q = 31.2, p = 20.8. Find p when q = 15.3.

 and that one :)

lgbasallote · Answer

y = k/x will be your equation since it's inversely proportional

15 = k/18

270 = k

10 = 270/x

10x = 270
x = 27

anonymous · Answer

x=k/y
15=k/18
k=270
for x=10,
10=270/y
y=27
the 2nd number is 27

lgb duhhh

lgbasallote · Answer

p = kq

20.8 = k 31.2

k = 20.8/31.2
k = 0.66

p = 0.66 (15.3)

p = 10.2
