Answer:
-2°F
Step-by-step explanation:
To convert temperatures from degrees centigrade to degrees fahrenheit, we use this formula;
(C × [tex]\frac{9}{5}[/tex]) + 32 , where C is the temperature in degrees centigrade.
(-18.9°C × [tex]\frac{9}{5}[/tex]) + 32 = -34.02 + 32 = -2.02°F
That is -2°F (rounded up to nearest degree fahrenheit)
