The temperature on a summer afternoon is 84°f. define a variable and write an expression to find the temperature after it changes. then evaluate your expression for a decrease of 14 degrees fahrenheit. 14 – c; 14 – (–84) = 70; 70°f 84 – c; 84 – (–14) = 98; 98°f 14 + c; 14 + (–84) = 98; 98°f 84 + c; 84 + (–14) = 70; 70°f
