Answer:
The required expression for 10 hours is [tex]-2\times 10[/tex]
Step-by-step 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 [tex]-2x[/tex]
Where minus sign represents the Temperature dropped
Substitute x = 10 in above expression.
[tex]-2(10)[/tex]
[tex]-2\times 10[/tex]
[tex]-20[/tex]
Hence, the required expression for 10 hours is [tex]-2\times 10[/tex]
