Write an integer fo each solution 200 feet below sea level

Problem: The highest elevation in North America is Mt. McKinley, which is 20,320 feet above sea level. The lowest elevation is Death Valley, which is 282 feet below sea level. What is the distance from the top of Mt. McKinley to the bottom of Death Valley?

Solution: The distance from the top of Mt. McKinley to sea level is 20,320 feet and the distance from sea level to the bottom of Death Valley is 282 feet. The total distance is the sum of 20,320 and 282, which is 20,602 feet.

The problem above uses the notion of opposites: Above sea level is the opposite of below sea level. Here are some more examples of opposites:

top, bottom  |  increase, decrease  |  forward, backward  |  positive, negative

We could solve the problem above using integers. Integers are the set of whole numbers and their opposites. The number line is used to represent integers.

Step-by-step explanation:

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
