Chapter 1: Q40. (page 9)

Evaluate each expression if $w = 6, x = 0.4, y = \frac{1}{2},$ and $z = - 3$
$w (8 - y)$

Short Answer

Expert verified

Expression $w (8 - y)$ results into 45

Step by step solution

- Order for simplification

To evaluate any expression involving more than one operation, follow the below order of operations:

First evaluate expressions inside grouping symbols like parentheses ( ) or brackets [ ].
Evaluate the exponents.
Perform Multiplication and division from left to right.
Perform addition and subtraction from left to right.

- Substitute given values

Substitute 6 for $w$ and $\frac{1}{2}$ for $y$ into given expression

$w (8 - y) = 6 (8 - \frac{1}{2})$

- Simplify 68-12

To evaluate the value of the given expression, first simplify the expression inside the parenthesis and then multiply resultant numbers

$\begin{matrix} 6 (8 - \frac{1}{2}) = 6 (\frac{16}{2} - \frac{1}{2}) \\ = 6 (\frac{16 - 1}{2}) \\ = 6 (\frac{15}{2}) \\ = \frac{90}{2} \\ = 45 \end{matrix}$

Thus, value of $w (8 - y)$ is 45
