Question

please help!! 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. What is the actual temperature if the wind chill temperature is -24.3°F and the wind is blowing at 20 miles per hour? thank you

Answer 1

-24.3 = 1.42T - 38.5

first, move -38.5 to the other side of the equal sign. because you’re moving to a different side, you must change the negative sign to a positive.

14.2 = 1.42T

now, you have to divide both numbers by 1.42 to isolate T.

10 = T

The actual temperature is 10°F.
