Answer:

10

Step-by-step explanation:

If you have to divide x by two, and y varies directly toward x, y also has to divide by two. 20/2 is 10.

Answer: 10

Step-by-step explanation:

Given ; y = 20

x = 4

since y varies directly as x,

y = kx

where k is the value of proportionality.

Input the values

20 = k (4)

20 = k4

dividing both sides by 4

20/4 =k

k = 5

To find the value of y when x = 2,

y = kx

y = 5 (2)

y = 10
