The temperature on a summer afternoon is 76°f. define a variable and write an expression to find the temperature after it changes. then evaluate your expression for a decrease of 8 degrees fahrenheit. 76 – c; 76 – (–8) = 84; 84°f 8 – c; 8 – (–76) = 68; 68°f 76 + c; 76 + (–8) = 68; 68°f 8 + c; 8 + (–76) = 84; 84°f
