1. The problem is to translate the verbal expressions into algebraic expressions or vice versa. 2. Let's analyze each expression: - $\frac{12}{n}$ means 12 divided by $n$. - $9.4y$ means 9.4 times $y$. - $5x + 2$ means 5 times $x$ plus 2. - $20 + \frac{P}{3}$ means 20 plus $P$ divided by 3. - $\frac{7y}{x^2}$ means 7 times $y$ divided by $x$ squared. 3. These are algebraic expressions representing quantities and operations described verbally. 4. For example, "12 divided by a number $n$" is written as $\frac{12}{n}$. 5. "9.4 times $y$" is written as $9.4y$. 6. "5 times $x$ plus 2" is $5x + 2$. 7. "20 plus $P$ divided by 3" is $20 + \frac{P}{3}$. 8. "7 times $y$ divided by $x$ squared" is $\frac{7y}{x^2}$. This shows how to translate between verbal expressions and algebraic symbols.
