Question

The formula for converting from Celsius to Fahrenheit is F=9/5C+32. The Fahrenheit temperature of a certain city has never exceeded 86 degrees. How would you describe this using Celsius temperature?

Answer 1

The temperature in Celsius in this city has never exceeded 30 °C

Explanation:

Just substitute F by the temperature in Fahrenheit and solve the equation:

86 = 9C/5+32 Multiply both sides by 5

5×86 = 9C +32×5

430 = 9C + 160 Subtract 160 in both sides

270 = 9C Divide both sides by 9

30 = C
