C = 5/9(F - 32)
C = 50

50 = 5/9(F - 32)
50 * 9/5 = F - 32
90 = F - 32
90 + 32 = F
122 = F <===

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. \(C=\dfrac{5}{9}\times (F-32)\\\\9C=5\times (F-32)\\\\9C=5F-160\\\\5F=9C+160\\\\F=\dfrac{1}{5}\times (9C+160)------(1)\)

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).

\(F=\dfrac{1}{5}\times (9\times 50+160)\\\\F=\dfrac{1}{5}\times (450+160)\\\\F=\dfrac{1}{5}\times (610)\\\\F=122\)

Hence 50°C= 122°F.
