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).

Question:

Which of the following expressions represents the distance between 1.7 and −1/2 on a number line?

Choose 1  

C. None of the above

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;

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,

Substitute for Difference;

Hence, the correct option is B
