Answer:
The temperature in Celsius in this city has never exceeded 30 °C
Step-by-step 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
