A cold wave hit Chicago when the temperature was 62°F. During the cold wave, the temperature dropped 2 degrees every hour. How many hours did it take for the temperature to fall below 40°F?

First find the equation of the problem, y=-2x+62 Plug 40 in for y 40=-2x+62 And solve for x -22=-2x (I subtracted 62 from both sides) x=11

There are more than 11 hours was it before the **temperature **was below 40F.
Used the concept of **inequality **that states,
A relation by which we can compare two or more mathematical expressions is called an inequality.
Given that,
A **cold **wave hit Chicago when the temperature was 62F.
During the cold wave, the **temperature **dropped 2 degrees every hour.
Let us assume that the number of hours = h
Hence, the **inequality **for the given condition is,
62 - 2h < 40
Solve for h;
62 < 40 + 2h
62 - 40 < 2h
22 < 2h
11 < h
Therefore, the **solution **is 11 < h.

The temperature in Chicago will fall below 40°F after more than 11 hours from an initial temperature of 62°F, decreasing by 2 degrees each hour.
