If xx and yy are in direct proportion and yy is 4 when xx is 6, find yy when xx is 3.

Question

Answer
Attempt 1 out of 2

y, equalsy=

Answer 1

y = kx

To find the constant of proportionality (k), we will use the given values xx=6 and yy=4:

4 = 6k

k = 4/6
k = 2/3

Now that we have the value of k, we can find yy when xx is 3:

y = (2/3) * 3
y = 2

Therefore, when xx is 3, yy is 2.
