Chapter 1: Q41. (page 9)

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

Short Answer

Expert verified

Expression $z (x + 1)$ results into $- 4.2$

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 $0.4$ for $x$ and $- 3$ for $z$ into given expression

$z (x + 1) = (- 3) (0.4 + 1)$

- Simplify -30.4+1

To evaluate the value of the given expression, first simplify the expression inside the parenthesis and then simplify as shown below

$\begin{matrix} (- 3) (0.4 + 1) = (- 3) (1.4) \\ = - 4.2 \end{matrix}$

Thus, value of $z (x + 1)$ $- 4.2$ is
