Final answer:
To convert -20°C to Fahrenheit, use the formula F = (9/5 × C) + 32. After performing the math, you'll find that -20°C is equivalent to -4°F, which is answer A.
Step-by-step explanation:
To convert -20°C to degrees Fahrenheit using the formula F = 9/5C + 32, we can substitute -20 for C and perform the calculation:
F = (9/5 × (-20)) + 32
F = (-36) + 32
F = -4°F
However, please note that there is a typo in the original formula provided. The correct formula for converting Celsius to Fahrenheit is F = (9/5 × C) + 32, not F = 95C + 32. With the correct formula, the converted temperature is -4°F, which corresponds to option A.
