Answer:
[tex]-40<x<284[/tex]
Step-by-step explanation:
We must convert the given temperatures from degrees Celsius to degrees Fahrenheit
The formula is:
[tex]C=\frac{5}{9}(F-32)[/tex]
Where C is the temperature in degrees Celsius and F is the temperature in degrees Fahrenheit
Then we must replace the temperature in degrees Celsius and solve the equation for F
[tex]C*\frac{9}{5}=(F-32)[/tex]
[tex]F=C*\frac{9}{5}+32[/tex]
[tex]F=(-40)*\frac{9}{5}+32[/tex]
[tex]F=-40\ \°F[/tex]
[tex]F=(140)*\frac{9}{5}+32[/tex]
[tex]F=284\ \°F[/tex]
The Fahrenheit temperature range in which the antifreeze protects the car is:
[tex]-40<x<284[/tex]
