Hello, your answer is: <span>1079, because remember, this equation represents *800 - (-279) so, you need to use the method of KCC, or, k=keep, c=change, c=change. you keep the 800 positive, switch the (-) subtraction sign to a (+) addition sign, and also, make the (-279) a positive 279. so you turn out with: *800 + 279, which equals = 1079 *youre welcome!!!! can you please pick this answer as the brainliest??? please i really need it, thank you!!! :) </span>
