Question

Two quantities x and y vary directly. Complete the following table. also show you're workings

Answer 1

see explanation

Explanation:

Using the first 2 values for x and y given in the table, that is

x = 6 when y = 12 and x = 8 when y = 16

We can see that y = 2x or x = 0.5y, thus

Values of y are twice values of x and values of x are half the values of y

The table can then be completed using this information as

x | 6, 8, 9, 12, 16, 18, 20, 24

and

y | 12, 16, 18, 24, 32, 36, 40, 48
