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
