plz help me with this final!!!

Answer:
Please check the explanation.
Step-by-step explanation:
Given
The location of Point C on the number line = 19.9
Thus, the distance or length between B and C can be calculated by subtracting the point B units from point C units.
BC = 19.9 - 14
= 5.9 units
Therefore,
BC = 5.9 units
Also, the distance or length between C and A can be calculated by subtracting the point C units from point A units.
CA = -13.4-19.9
= -33.3 units
Therefore,
CA = -33.3 units
As the length or distance can not be negative, hence
CA = 33.3 units
