Chapter 7.4, Problem 58S

To determine

To solve and check: the given equation

Answer to Problem 58S

The required answer is $b=\frac{1}{6}$

Explanation of Solution

Given:

  $5=30b$

Calculation:

The expression is $5=30b$ .

The objective is to solve the above expression.

The expression is $5=30b$ .

  $\begin{array}{l}5=30b\\ \frac{5}{30}=\frac{30b}{30}\\ b=\frac{1}{6}\end{array}$

Check solution:

Substitute $b=\frac{1}{6}$ in expression $5=30b$ .

  $30\times b=30\times \frac{1}{6}$

= 5 (correct)

Hence, $b=\frac{1}{6}$

Conclusion:

Hence, the required answer is $b=\frac{1}{6}$
