Example 1
Use the number line to find the coordinate of P that represents the weighted
average of each set of points with the given conditions.
1. Point B weighs three times as much as point D.
E
H+
2. Point C has a weight of 3, and point E has a weight of 5.
3. Point A has a weight of 2, and point D has a weight of 3.
Can someone show how you would find the weight for number 1
