Help asap plz ill give a gold medal. the label on cars antifreeze claims to protect the car between -30celsius and 130celsius. to convert Celsius temperature Fahrenheit temperature, the formula is, c=5/9(F-32). Write an solve and inequality to determine the Fahrenheit temperature range at which antifreeze protects the car.
The inequality would start out looking like this: [tex]-30\ \textless \ \frac{5}{9} (F-32)\ \textless \ 130[/tex] Now it's just a matter of solving the inequalities simultaneously. Get rid of the fraction by multiplying everything by 9: [tex]-270\ \textless \ 5(F-32)\ \textless \ 1170[/tex] Then distribute the 5 into the parenthesis: [tex]-270\ \textless \ 5F-160\ \textless \ 1170[/tex] Now add 160 everywhere: [tex]-110\ \textless \ 5F\ \textless \ 1330[/tex] and finally divide everything by 5: -22<F<266
