In a certain city, the temperature normally ranges from 20 degrees Fahrenheit and 80 degrees Fahrenheit. Write a compound inequality that describes abnormal temperature ranges for this city and then convert that inequality to degrees Celsius. F=9/5C+32

Answer 1

20 < T < 80 , where T is temperature in Fahrenheit

Since C = (5/9)(F - 32) , I will let you do the conversion

Answer 2

explain how the inequality -4'c> -9'c describes how the temperatures are related
