An elevator on the 10th floor goes down 9 floors. Then it goes up 19 floors, down 3, and finally down 12. What floor does it end up on? Write an equation to show how you found your answer
The elevator ends up on the 15th floor.
10 - 9 + 19 - 3 - 12 = 15
10- (-9) + 19- (-3)- (-12)
whats the answer??
To find the floor where the elevator ends up, we need to keep track of its movements and calculate the final position. Let's break it down step by step:
1. Start at the 10th floor.
2. The elevator goes down 9 floors, so subtract 9: 10 - 9 = 1st floor.
3. Next, it goes up 19 floors, so add 19: 1 + 19 = 20th floor.
4. Then it goes down 3 floors, so subtract 3: 20 - 3 = 17th floor.
5. Finally, it goes down 12 floors, so subtract 12: 17 - 12 = 5th floor.
Therefore, the elevator ends up on the 5th floor.
Equation:
Starting floor - 9 + 19 - 3 - 12 = Final floor
10 - 9 + 19 - 3 - 12 = 5
