Question

Geometry: Find Each Length: AB. Another is BC.

Its a number line lined from left to right:

<-4,-3,A -2.5, -2,-1,0,B 1, 2,3,C 3.5, 4, D 5>

Question 1: Length of AB

Question 2: BC

I know A is -2.5, B is 1, and C is 3.5 but am unsure of what to do next, and how to solve. I have to work it out, but have only tried AB+BC=AC, so i added 3.5+(-2.5) and got 1.0, i need help, thanks

Answer 1

Since it's a number line why don't you try counting the lengths. Anyway the length AC is the length of AB + BC.

The length from A to B is 3.5, and B to C is 2.5
So from A to C it is 6

Answer 2

to find the length what you have to do is:

just subtract the two points, the resultant will be your answer.
