Question

A lobster fisherman moves a lobster trap from 20 feet below see level to a location that is 15 feet deeper. Draw a number line and write an addition equation that models this situation. What integer represents the new location relative to sea level?

Answer 1

20 ft. Below sea level is -20 and 15 ft. Below sea level is -15, add -20+-15 ( the new integer is -35)

Answer 2

`-20+(-15)=-35`

Explanation:

We are given that a lobster fisherman moves a lobster trap from 20 feet below see level to a location that is deeper 15 feet.

We have to draw a number line and write an addition equation that models this situation and find the value of integer that represents the new location relative to sea level.

Lobster fisherman moves from 20 feet below the sea level therefore , it taken as negative integer -20.

The lobster fisherman goes to a location 15 feet deeper then it takes as negative integer.

The equation is given by

`-20+(-15)`

=-20-15=-35

Hence, the integer -35 represents the new location relative to sea level.
