Chapter 1: Q14. (page 48)

Evaluate each expression if $a = 12, b = 0.5, c = - 3$ and $d = \frac{1}{3}$
$6 b - 5 c$

Short Answer

Expert verified

Expression $6 b - 5 c$ results into $18$ .

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.

– Perform Substitution

To evaluate given expression, first substitute the value of $0.5$ for b and $- 3$ for c in expression.

$6 b - 5 c = 6 (0.5) - 5 (- 3)$

– Perform Simplification

To simplify further, multiply the terms from left to right then perform addition in the terms.

$\begin{matrix} 6 (0.5) - 5 (- 3) = 3 + 15 \\ = 18 \end{matrix}$
