Question

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

Step-by-step explanation:

20≤F≤80

20=9/5c+32

-12=9/5c

-60=9c

-6.7=c

80=9/5c+32

48=9/5c

240=9c

26.7=c

-6.7≤C≤26.7
