Chapter 4.3, Problem 75CCR

To determine

To find: theexpression and the value of expression.

Answer to Problem 75CCR

The expression is $|24-(-6)|$ and the distance from the top of the buoy to the bottom of the buoy is $30$ inches.

Explanation of Solution

Given information:

The top of an ocean buoy is $24$ inches above sea level and the bottom of the buoy is $6$ inches below sea level.

Calculation : since, The top of an ocean buoy is $24$ inches above sea level and the bottom of the buoy is $6$ inches below sea level, so to find the distance from the top of the buoy to the bottom of the buoy the expression can be defined by the subtraction,

The expression can be defined as:

  $|24-(-6)|$

To solve the expression, add 6 to the 24,

  $\begin{array}{l}|24-(-6)|=|24+6|\\ |24-(-6)|=30\text{ [add]}\end{array}$

The distance from the top of the buoy to the bottom of the buoy is

  $30$ inches.
