Explanation:

Consider the provided information.

You track the temperature from the time you eat lunch to the time you go to bed.

It drops 2 degrees each hour for 10 hours.

Let x is the number of hours and it drops 2 degrees each hour.

Thus, the required expression is
`-2x`

Where minus sign represents the Temperature dropped

Substitute x = 10 in above expression.

`-2(10)`

`-2* 10`

`-20`

Hence, the required expression for 10 hours is
`-2* 10`
