It would certainly be easier to analyze the situations if you had not run them all together into one long sentence.
Take the last one. Clearly the net charge is 12(0 + 1 + (-1)) = 12(0) = 0
Surely you have some thoughts on the others. Don't get rattled by all the words; just think about what they are really asking.
Which of the following situations describe quantities that combine to make 0?
During the top of the fourth inning of a baseball game, the Ravens scored three runs. During the bottom of the fourth inning, the Raiders scored five runs to tie the game.
Jacoby went on a hiking trip on the Rocky Bend Loop. Starting at an elevation of 1,200 feet, he hiked up the eastern trail leading to a change in elevation of 782 feet to get to the campsite. The next day he hiked down the western trail which had a change in elevation of 782 feet to get back to his car.
Emily received a check from her grandmother for $40.00 for her birthday. To cash the check, her bank requires her to deposit the funds into her account. Since she wanted to spend the money that afternoon, she withdrew $40.00 in the same transaction.
To start the second half of the basketball game, the Eagles made a jump shot for two points. The Bulldogs then took the ball down the court on a fast break and made a layup for two points.
Marcus runs a sightseeing service in the Appalachian Mountains. The first leg of the tour is a 16.2-mile horseback ride from the stables up the side of a mountain. The second leg of the tour is a 20.6-mile four-wheeler ride taking a different path down the mountain to the customer parking lot.
A carbon 12 atom has six neutrons, six protons, and six electrons. The neutrons have no charge, each proton has a positive charge, and each electron has a negative charge of the same magnitude.

To determine which situations describe quantities that combine to make 0, we need to look for situations where positive quantities are offset by equal negative quantities. Let's consider each situation:
Situation 1: In the baseball game, the Ravens scored three runs, and the Raiders scored five runs. Since the Ravens' runs were positive and the Raiders' runs were also positive, these quantities do not combine to make 0.
Situation 2: Jacoby's hiking trip involves a change in elevation of 782 feet while going up the eastern trail and then an equal change in elevation of 782 feet while going down the western trail. These positive and negative changes in elevation cancel each other out, resulting in a combined change of 0 feet. Therefore, this situation describes quantities that combine to make 0.
Situation 3: Emily received a check for $40.00 and then immediately withdrew $40.00 in the same transaction. The positive value of the check is offset by the equal negative value of the withdrawal, resulting in a combined amount of 0 dollars. Thus, this situation describes quantities that combine to make 0.
Situation 4: In the basketball game, the Eagles made a jump shot for two points, and the Bulldogs made a layup for two points. Both scores are positive and do not combine to make 0.
Situation 5: Marcus's sightseeing tour includes a 16.2-mile horseback ride up the mountain and a 20.6-mile four-wheeler ride down the mountain. These positive and negative distances cancel each other out, resulting in a combined distance of 0 miles. Hence, this situation describes quantities that combine to make 0.
In conclusion, situations 2 and 5 describe quantities that combine to make 0.
Situation 1: In the baseball game, the Ravens scored three runs, and the Raiders scored five runs. Since the Ravens' runs were positive and the Raiders' runs were also positive, these quantities do not combine to make 0.
Situation 2: Jacoby's hiking trip involves a change in elevation of 782 feet while going up the eastern trail and then an equal change in elevation of 782 feet while going down the western trail. These positive and negative changes in elevation cancel each other out, resulting in a combined change of 0 feet. Therefore, this situation describes quantities that combine to make 0.
Situation 3: Emily received a check for $40.00 and then immediately withdrew $40.00 in the same transaction. The positive value of the check is offset by the equal negative value of the withdrawal, resulting in a combined amount of 0 dollars. Thus, this situation describes quantities that combine to make 0.
Situation 4: In the basketball game, the Eagles made a jump shot for two points, and the Bulldogs made a layup for two points. Both scores are positive and do not combine to make 0.
Situation 5: Marcus's sightseeing tour includes a 16.2-mile horseback ride up the mountain and a 20.6-mile four-wheeler ride down the mountain. These positive and negative distances cancel each other out, resulting in a combined distance of 0 miles. Hence, this situation describes quantities that combine to make 0.
In conclusion, situations 2 and 5 describe quantities that combine to make 0.
