Question

On a number line, point S has coordinate 4.8 and point T has coordinate –2.3.

Which expressions represent the distance between point S and point T?



Choose all answers that are correct.


A. |4.8 +(-2.3)|



B. |2.3 - 4.8 |



C. | 2.3 - 4.8 |



D. | 4.8 _ ( -2.3) |

Answer 1

The only answer that would work would be D) | 4.8 - ( -2.3) |

Explanation:

This is because the distance is the absolute value of the difference of the two numbers. B and C would also work, but the 2.3 is not negative. A does not work because it is addition.
