Answer:
- 23
- 6
- 25
- 30
- 11
Explanation:
For these problems, you need to know that the sum of segment lengths on a line is the length of the line. You also need to know that a midpoint divides a segment into two equal parts.
1. JH = JI +IH = 12 + 11
JH = 23
__
2. KJ = JI
6 = JI
__
3. The distance between two points on a number line is found by subtracting the number at the left end from the number on the right end.
SU = U - S = 10 -(-15)
SU = 25
__
4. TV = V - T = 25 -(-5)
TV = 30
__
5. RS +ST = RT
RS + 2 = 13
RS = 11
