Pb is a line segment on a number line it has endpoints at -2 and 12 what is the coordinate of its midpoint

There is a difference of 14 units between -2 and 12. To find the coordinate in the middle, just add 7, half the distance between -2 and 12, to -2 and subtract 7 from 12. That gives you the coordinate 5.

Iwould like to think so. what’s the question you need with?

The amount used= 13.04- 1.9 = 11.14
