Given : The number line shows the distance in meters of two skydivers, A and B, from a third skydiver located at point X:
To Find : Write an expression using subtraction to find the distance between skydivers A and B.
Solution:
an expression using subtraction to find the distance between skydivers A and B.
XB - XA
Distance between AB
= XB - XA
XB = 0.5
XA = -2.5
Distance between AB = 0.5 - (-2.5)
Distance between AB = 0.5 + 2.5
Distance between AB = 3
Additive inverse of a number a is the number that, when added to a , yields zero
negation of each other
