Which of the following is a real world problem that could be solved with the sum -22+9?
One possible real-world problem that could be solved with the sum -22+9 is calculating the change in temperature over time. Let's say the temperature initially dropped by 22 degrees Celsius and then increased by 9 degrees Celsius. We can find the net change in temperature by adding the temperature decrease (-22) and the temperature increase (+9). The sum (-22+9) would result in a net decrease of 13 degrees Celsius, indicating the overall change in temperature.

Another real-world problem that could be solved with the sum -22+9 is determining the overall change in a person's bank account balance. Let's say someone had a balance of -22 dollars, indicating that they had a negative balance or were in debt. If they then received a deposit of 9 dollars, it would increase their balance. By adding the initial balance (-22) and the deposit (+9), we can find the new balance, which would be -22+9 = -13 dollars. Thus, the sum helps determine the new balance and the overall change in the person's account.
The problem that could be solved using the sum -22+9 is calculating the change in temperature.
For example, suppose the temperature of a room is initially -22 degrees Celsius, and it increases by 9 degrees Celsius. To find the final temperature, you can add these values together: -22 + 9 = -13 degrees Celsius.
To determine which real-world problem could be solved with the sum -22+9, we first need to understand what the sum represents. The sum -22+9 represents the addition of -22 and 9. In mathematics, when we add a negative number to a positive number, it is essentially the same as subtracting the absolute value of the negative number from the positive number.
So, in this case, -22+9 can be calculated as (-22) + (9), which equals -13.
Now, let's think of a real-world problem that can be solved using this sum. One possible scenario would be measuring a temperature drop or decrease. Suppose you are measuring the temperature outside, and you begin at -22 degrees Celsius. Then, after some time, the temperature decreases by 9 degrees Celsius. To determine the new temperature, you would add the decrease (-9) to the starting temperature (-22). The result, -13 degrees Celsius, would represent the new temperature after the temperature drop.
Therefore, a real-world problem that could be solved using the sum -22+9 is measuring a temperature drop from -22 degrees Celsius to -13 degrees Celsius.
