Answer: y=6 for x=1 and x = 5 for y = 30.
Step-by-step explanation: We are given a table of x and y values:
x : 1 3 ? 7 9
y : ? 18 30 72 54.
The values of x and y are in proportion.
Let us check the ratio of values of x to y.
When x=3, we have y =18.
Therefore x/y = 3/18 = 1/6.
So, all values of x and y should be in ratio 1/6.
In order words, the value of y's are 6 times the values of x's.
So, for x=1, y= 6×1 = 6
For y =30 , x= 30/6 = 5
Therefore, we need to fill y=6 for x=1 and value of x = 5 for y = 30.
