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

point A is at -1.5
point B is at 0.5

to find the distance between these two values, we subtract the higher value minus the lower value.

0.5 - (-1.5)

solve using additive inverses (hint: A - B = A + (-B), you can treat 0.5 as your A and -1.5 as your B)
