Question

evaluate the expression for d = -3 and f = 19. f - 13|d| =

Explanation:

Step1: Find the absolute - value of d

The absolute - value of a number \(a\), denoted as \(|a|\), is the non - negative value of \(a\). Given \(d=-3\), then \(|d| = |-3|=3\).

Step2: Substitute the values of f and |d| into the expression

We have the expression \(f - 13|d|\), substituting \(f = 19\) and \(|d|=3\) into it. So \(19-13\times3\).

Step3: Perform the multiplication first

According to the order of operations (PEMDAS: Parentheses, Exponents, Multiplication and Division first, then Addition and Subtraction), we calculate \(13\times3 = 39\). Then the expression becomes \(19 - 39\).

Step4: Perform the subtraction

\(19-39=-20\).

Answer:

\(-20\)
