Question

the temperature on a summer day is 77 degree fahrenheit , the formula convert temperature to degrees Celsius =5/9 (f-32). what is the corresponding temperature in degrees celcius?

Answer 1

`C=(5)/(9)(F-32)\\\\F=77\\\\put\ value\ of\ F\ to\ equation:\\\\C=(5)/(9)(77-32)=(5)/(9)\cdot45=5\cdot5=25\\\\\boxed{77^o F=25^o C}`
