Answer 1

Step-by-step explanation:

Given;

We are given the following expression;

`(|2a|-b)/(3)`

Where;

`a=7,b=-4`

Required;

Find the value of the expression given the values of the variables a and b.

Step-by-step solution;

Take note that the lines that confine 2a is the absolute value symbol. It means the values within those two lines is always a positive value.

We shall now substitute the values of a and b into the expression as follows;

`\begin{gathered} (|2a|-b)/(3) \\ \\ =(|2*7|-(-4))/(3) \\ \\ =(14+4)/(3) \\ \\ =(18)/(3) \\ \\ =6 \end{gathered}`

ANSWER:

The value of the expression is 6. Option D is the correct answer.
