$A.-19 B.-11 C.-7 D.11$

Step-by-Step Solution

Answer

The solution is $-19$.

Step 1- Apply the following concept.

Absolute value is a value that describes the given number's distance on the number line from 0. The absolute value of a number is always positive even if the number is negative. It is also known as the numerical value or the magnitude of the given number.

Step 2- Step description.

Consider the equation $-|-9|-\left|4\right|-3|5-7|$.

 

Simplify the equations follows:

$\begin{array}{l}=-|-9|-\left|4\right|-3|5-7|\\ =-9-4-3\left(2\right)\\ =-9-4-6\end{array}$

Step 3- Step description.

Simplify the equation further.

$\begin{array}{l}=-9-4-6\\ =-19\end{array}$

Therefore, the value is $-19$.
