If the wind is blowing at 20 miles per hour, you can find the wind-chill temperature W (in degrees Fahrenheit) by using the equation W = 1.42T-38.5, where T is the actual temperature (in degrees Fahrenheit). Solve this equation for T and write a reason for each step on your paper. Then find the actual temperature if the wind chill temperature is -24.3°F and the wind is blowing at 20 miles per hour.
