Question

A fisher finder shows a large fish at 13 ft below the surface and a smaller fish 4 ft below surface. what is the expressions that are equivalent to the distance between the fish

Answer 1

Distance = 9 ft

Step-by-step explanation:

We can represent the position of the large fish with the number -13 because it is 13ft below the surface. In the same way, we can represent the position of the smaller fish with the number -4.

Then, the distance between the fish will be the absolute value of the difference between their positions. So, the expressions that are equivalent to the distance between the fish are:

| - 13 - ( - 4) | = | - 13 + 4| = 9

or

| -4 - (- 13) | = | - 4 + 13 | = 9

Therefore the distance between the fish is 9 ft
