Question

Please help. Winter break packets are the worst :/

Answer 1

y = kx or k = y/x or x = y/k

5) y = kx = (1.5)(50) = 75
6) x = y/k = (15/4) / (1/4) = 15/4 x 4 = 15
7) y = kx = (1/2)(14/5) = 7/5 or = 1 2/5 or = 1.4
8) x = y/k = 38/16 = 2.375

Answer 2

y/50=1.5
y=75

3.75/x=.25
3.75/.25=x
x=15

y/2.8=.5
y=1 2/5

38/x=16
38/16=x
19/8=x
