A building has 23 floors of offices above ground and 5 floors below ground. Nathan parks on the 2nd floor below ground and has an office on the 18th floor. The ground floor is floor zero. Which absolute value expression represents how many floors he must go up to get from his car to his office?
The absolute value expression that represents how many floors Nathan must go up to get from his car to his office can be found by taking the absolute difference between the floor number he parked on and the floor number of his office, that is:
|18 - (-2)| = |18 + 2| = 20
Therefore, Nathan must go up 20 floors to get from his car to his office.
This time answered did it right.
To find out how many floors Nathan must go up to get from his car to his office, we can subtract the floor number of his car from the floor number of his office.
The floor number of his car is -2 (2 floors below ground), and the floor number of his office is 18 (18 floors above ground).
So, the absolute value expression that represents how many floors Nathan must go up is:
|18 - (-2)|
Now let's simplify this expression:
|18 - (-2)| = |18 + 2| = |20|
Therefore, the absolute value expression that represents how many floors Nathan must go up to get from his car to his office is |20|.
To determine the number of floors Nathan must go up to get from his car to his office, we need to calculate the absolute difference between the floor where he parked (2nd floor below ground) and the floor where his office is located (18th floor).
First, let's understand the relative position of the floors. Since the ground floor is floor zero, the 2nd floor below ground would be -2, and the 18th floor above ground would be +18.
To find the number of floors he must go up, we can calculate the absolute value of the difference between the two floors:
| -2 - 18 | = |-20| = 20
Therefore, the absolute value expression that represents how many floors Nathan must go up to get from his car to his office is | -2 - 18 | = 20.
