Question

In countries like USA and Canada, temperature is measured in Fahrenheit, whereas in countries like India, it is measured in Celsius. Here is a linear equation that converts Fahrenheit to Celsius: F = ( 9/5 )C + 32 (i) If the temperature is -15°F, what is the temperature in Celsius? (ii)Find the temperature which is numerically the same in both Fahrenheit and Celsius

Answer 1

Answer:

ii)Put F=C=x in given equatin, we get

5

4x

=−32, from which we get x=−40

Yes, there is a temperature which is numerically the same in both fahrenheit and celsius, the numerical value is −40.
