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

The colors got a little messed up but you get the idea, A is at -1.5, X is at 0, B is at 0.5

first part: Write an expression using subtraction to find the distance between the two jellyfish. (5 points)

---> simply write (point A) - (point B), fill in the appropriate numbers from the number line, then put your expression inside absolute value signs to indicate that we are only considering the positive difference (distance) between the two values
