Answer:
122°F is the correct answer.
Step-by-step explanation:
We are given a formula to convert:
°F to °C as:
C =5/9 (F – 32).
i.e. [tex]C=\dfrac{5}{9}\times (F-32)\\\\9C=5\times (F-32)\\\\9C=5F-160\\\\5F=9C+160\\\\F=\dfrac{1}{5}\times (9C+160)------(1)[/tex]
Now we are asked to convert 50°C to °F.
i.e. we are given C=50 and asked to find the value of F from equation (1).
[tex]F=\dfrac{1}{5}\times (9\times 50+160)\\\\F=\dfrac{1}{5}\times (450+160)\\\\F=\dfrac{1}{5}\times (610)\\\\F=122[/tex]
Hence 50°C= 122°F.
