8.(iv) 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:
(iv) If the temperature is 0°C, what is the temperature in Fahrenheit and if the temperature is 0°F, what is the temperature in Celsius?
If the temperature is 0°C,
if the temperature is 0°F,
Thus, if the temperature is 0°C ,then temperature in fahrenheit is 32 and if the temperature is 0°F ,then temperature in celsius is -17.8 .
