Question

At what temperature both the centigrade and Farenheit scales shows some value

a) 40 C​

Answer 1

Answer:

- 40 degrees

Step-by-step explanation:

The formula for equating the two is

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

Let's take both values of C and F as -40 degrees

$\frac{-40}{5} = \frac{-40-32}{9}$

$-8 =\frac{-72}{9}$

$-8 = -8$

Hence proved

F−32

Let's take both values of C and F as -40 degrees

\frac{-40}{5} = \frac{-40-32}{9}

−40−32

-8 =\frac{-72}{9}−8=
