Question

at what temperature do the fahrenheit and celsius scale coin​

Answer 1

Answer:

The correct answer is option(A).

The formulas for converting between degree Celsius and degree Fahrenheit are:

°F=(°C×59)+32

°C=(°F−32)×95

To find the temperature when both are equal, we use an old algebra trick and just set ºF = ºC and solve one of the equations.

°C=(°C∗×59)+32

−(°C×59)=32

−54×°C=32

°C=−32×45

°C=−40

°F=(°F×59)+32

°F−(°F×59)=32

−54×°F=32

°F=−32×54

°F=−40

So the temperature when both the Celsius and Fahrenheit scales are the same is -40 degrees.
