A scuba diver is swimming at 43 feet below sea level A scuba diver is swimming at 43 feet below sea level. He then goes down 18 more feet. Represent his new depth below sea level as an integer.

A submarine started out at 16 feet above sea level A submarine started out at 16 feet above sea level. Then it went down 60 feet and cruised there for 30 minutes. Afterwards the submarine came back up 40 feet. What integer represents the new depth of the submarine?

One morning, the temperature was 2° below zero One morning, the temperature was 2° below zero. By noon, the temperature rose 14° Fahrenheit (F) and then dropped 7°F by evening. What was the evening temperature?

Denver, Colorado is called “The Mile High City” because its elevation is 5280 feet above sea level. Someone tells you that the elevation of Death Valley, California is –282 feet. How much higher is Denver than Death Valley?

Find the opposite of 33.

Identify the quadrant in which points b, c, and D are located.

Reflect the point (5, 5) over the x-axis Reflect the point (5, 5) over the x-axis. What are the coordinates of the new location?

The point C (x, y) is reflected over the x-axis The point C (x, y) is reflected over the x-axis. Use arrow notation to describe the original point and its reflection.

Write the absolute value of each point on the number line below in order from least to greatest.
