Answer:
84 units
Explanation:
If B is the midpoint of line AC, then B divides AC into two equal parts (AB and BC).
Therefore:
AB=BC
2x-8=x+17
2x-x=17+8
x=25
Therefore, the measure of the line segment AC
=2(2x-8)
=2(2(25)-8)
=2(50-8)
=2(42)
AC=84 units
No, you can not tell because 8 could be in the tens place of one number, while 3 could be in the thousands place of anothrf number.
Answer:
