Question

The variables x and y have a proportional relationship, and y= 2/5 when x = 5/8

Which equation represents this relationship?
y= 9/40 x
y=16/25 x
y=1 9/16 x
y= 1/4 x

Answer 1

Answer:

B. 16/25 x is the answer

Step-by-step explanation:

lets find the proportional relationship,

y = kx

2/5 = k * 5/8

k = (2/5) /  (5/8)

k = 16/25

so if k, constant is 16/25

equation is:

y = 16/25 x

Answer 2

Answer:

the answer is 16/25x
