Question

which of these situations can be represented with an inter that, when combined with the opposite of -7, makes 0: you walk down 7 flights of stairs, you climb up 7 flights of stairs, you ear $7 dollars from your chores, you spend $7 on a movie, the temperature drops 7 degrees fahrenheit

Answer 1

When you ear $7 from your chores.

Explanation:

Say you owe your friend $7 from that box of candy that they bot you at the movies. You now have -$7 until you gain that money back. So, you did all of your chores, and you made $7! Now you have enough money to pay your friend back. You are now left with $0.

-$7 + $7 = $0
