The temperature on a summer afternoon is 76°F. Define a variable and write an expression to find the temperature after it change
Afina-wow [57]
Letting "c" be the value of the temperature change, looking at the choices, the nearest answer would be C. " 76 + c; 76 + (–8) = 68; 68°F ".

76 is the base or current temperature, then c would be the change in temperature experience. Since a decrease of 8 degrees is to be experienced, it is denoted by the negative symbol on 8.

Help for 10 points!!
dem82 [27]

The plus sign means that we have to sum all the terms inside of the second parenthesis, while the minus sign means that we have to change all the signs inside the last parenthesis:

(3x+5)+(2x-9)-(4x+3)=3x+5+2x-9-4x-3

Now we only have to gather all like terms:

3x+2x-4x+5-9-3 = (3+2-4)x+(5-9-3)=x-7
