Question

The formula to convert Celsius to Fahrenheit is f=9/5c+32 convert 62F to Celsius round to the nearest degree.

Answer 1

Answer:

The correct option is B.

Step-by-step explanation:

The formula to convert Celsius to Fahrenheit is

$F=\frac{9}{5}C+32$

Subtract 32 from both the sides.

$F-32=\frac{9}{5}C$

Multiply both sides by $\frac{5}{9}$.

$\frac{5}{9}(F-32)=C$

The formula to convert Fahrenheit to Celsius is

$C=\frac{5}{9}(F-32)$

Where, F is Fahrenheit.

We have convert 62F to Celsius round to the nearest degree. Put E=62.

$C=\frac{5}{9}(62-32)$

$C=\frac{5}{9}(30)$

$C=16.667$

$C\approx 17$

Therefore the correct option is B.

Answer 2

The Answer is B= 17c

62 = 9/5c + 32

62 - 32 = 30

30 / (9/5) = 17

C = 17
