Achoreographer uses a number line to position dancers for a ballet. dancers a and b have coordinates 5 and 23, respectively. find the coordinate for the following dancer based on the given location.
dancer e stands at a point that divides the line segment from dancer a to dancer b in a ratio of 2 to 1.
dancer e is
units from dancer a, so the coordinate for dancer e is
Dancer E is 12 units from Dancer A, so the coordinate for Dancer E is 17.
Distance from Dancer A to Dancer B.
AB = 23 - 5 = 18 units
Distance from Dancer A to Dancer E.
Dancer E is 12 units from Dancer A, so the coordinate for Dancer E is 5 + 12 = 17.
a; x = 0.5
-10x = -5
x = 0.5
