Question:
Which of the following expressions represents the distance between 1.7 and −1/2 on a number line?
Choose 1 answer:
[tex]A.\ |1.7 - 1/2|[/tex]
[tex]B.\ |1.7 -(-1/2)|[/tex]
C. None of the above
Answer:
[tex]B.\ |1.7 -(-1/2)|[/tex]
Step-by-step explanation:
Given
Numbers: 1.7 and -1/2
Required
Determine the distance
To calculate the distance, we start by calculating the difference between the given numbers;
[tex]Difference = 1.7 - (-1/2)[/tex]
Then, we calculate the distance;
In this case, the distance is meant to be positive; So, we'll introduce the symbol for absolute value;
Hence,
[tex]Distance = |Difference|[/tex]
Substitute [tex]1.7 - (-1/2)[/tex] for Difference;
[tex]Distance = |1.7 - (-1/2)|[/tex]
Hence, the correct option is B
The expression that represents the distance between 1.7 and -0.5 is given by |1.7 - (-0.5)| and this can be determined by using the arithmetic operations.
Given :
Numbers -- 1.7 and -0.5
The distance between two points 1.7 and -0.5 is given by:
Distance = 1.7 + |-0.5|
= 2.2
Now, check all the options in order to determine the correct option:
A) |1.7 - 0.5|
Simplify the above expression.
|1.7 - 0.5| = 1.2
B) |1.7 - (-0.5)|
Simplify the above expression.
|1.7 - (-0.5)| = |1.7 + 0.5| = 2.2
Therefore, the correct option is B).
