Answer:
the temperature does the numerical reading on a Celcius thermometer equal that Fahrenheit is -40°
Explanation:
⇒ °C = ° F.....................................( 2 )
replaicing ( 2 ) in ( 1 ):
⇒ °C = ( °C - 32 ) / 1.8
⇒ 1.8 * °C = °C - 32
⇒ 1.8°C - °C = - 32
⇒ 0.8°C = - 32
⇒ °C = ( -32 / 0.8 )
⇒ °C = - 40°C
