Question

June is 16 less than 11 times the average number of tornado's in december

Answer 1

The average number of tornado's in December is 22 and the average number of tornado's in June is 226

Explanation:

The complete question is

The average number of tornado's in June is 16 less than 11 times the average number of tornado's in December. If the difference between the average number of tornado's in June and December is 204,determine the average number of tornado's in December and June.

Let

x ----> the average number of tornado's in June

y ----> the average number of tornado's in December

we know that

`x=11y-16` ---> equation A

`x-y=204` ----> equation B

solve the system by substitution

substitute equation A in equation B

`11y-16-y=204`

solve for y

`10y=204+16`

`10y=220`

`y=22`

Find the value of x

`x=11y-16` ---->
`x=11(22)-16=226`

therefore

The average number of tornado's in December is 22 and the average number of tornado's in June is 226
