Question

The number line shows the distance in meters of two jellyfish, A and B, from a predator located at point X:

A horizontal number line extends from negative 3 to positive 3. The point A is at negative 1.5, the point 0 is labeled as X, and the point labeled B is at 0.5.
Write an expression using subtraction to find the distance between the two jellyfish. (5 points)

Show your work and solve for the distance using additive inverses. (5 points)

Answer 1

This is the expression -1.5-.5=-2
That the additive inverse are called opposites and lie on the other side of the number line from each other, so just do the opposite of the expression, which is adding both of them, instead of subtracting.

Answer 2

thanks you are the best
