To solve this problem you must apply the proccedure shown below:
1. You have the following formula given in the problem above: [tex]C=(5/9)(F-32)[/tex]
2. Then, to convert [tex]50[/tex] Degrees Celsius to Fahrenheit, you must solve for [tex]F[/tex], as following:
[tex]C=(5/9)(F-32) \\ 9C/5=F-32 \\ F=(9C/5)+32[/tex]
3. When you susbtitute the value of [tex]C
[/tex] into the formula, you obtain:
[tex]F=[(9)(50)/5]+32 \\ F=122 [/tex]
The answer is:[tex]122[/tex]
