Chapter 3: Problem 1
In Exercises 1-20, translate the phrase into a mathematical expression involving the given variable. 鈥8 times the width n 鈥
Short Answer
Expert verified
The expression is \(8n\).
Step by step solution
01
Identify the Components
The phrase given is "8 times the width n". Here, "8" is a constant, "times" suggests multiplication, and "n" represents the variable, which is designated as width in this context.
02
Translate to Mathematical Expression
Now we convert the phrase into a mathematical expression. "8 times the width n" translates to the multiplication of 8 by n. This can be represented mathematically as \(8 \times n\), or simply, \(8n\).
03
Final Expression
Therefore, the mathematical expression for "8 times the width n" is \(8n\).

Mathematical Translation
Mathematical translation is the process of converting a written phrase or sentence into a mathematical expression or equation. This skill is essential for solving word problems in algebra, allowing us to clearly and precisely define relationships and operations.
In our exercise, the phrase "8 times the width n" needs to be translated into a mathematical expression. The word "times" is a key indicator of multiplication. Another important word in the translation is "width," which is represented by a variable here, denoted as "n".
Understanding these linguistic cues helps us systematically convert verbal statements into algebraic sentences. The conversion process involves recognizing operation words (like 'times' for multiplication) and linking them to the corresponding mathematical operations. Without this skill, it can be challenging to move from the world of words to the precise realm of mathematics.

Algebra Basics
Algebra is a branch of mathematics dealing with symbols and the rules for manipulating these symbols. These symbols often represent numbers in equations and expressions.
A fundamental concept in algebra is understanding how to construct mathematical expressions and equations from verbal descriptions. This involves knowing the basic operations鈥攁ddition, subtraction, multiplication, and division鈥攁nd how to represent them with mathematical symbols.
For instance, in the phrase "8 times the width n," the basic algebraic operation is multiplication, indicated by "times." Hence, algebra allows us to transform the phrase into the expression \(8n\), where \(n\) is multiplied by 8. By grasping these basics, we can develop the ability to solve more complex problems. Algebra acts like a toolset that helps in recognizing patterns, solving equations, and understanding relations between different elements.

Variable Representation
In algebra, variables represent unknown numbers or can stand for quantities that may change. They are often denoted by letters like \(n\), \(x\), or \(y\). This letter acts as a placeholder for potential values that the variable might take on during calculations.
In our example "8 times the width n," \(n\) is the variable representing width. Variables help us generalize mathematical situations where the exact value isn't known or isn't necessary to solve the problem.
Using variables also allows us to create expressions and solve equations dynamically, addressing different scenarios based on what value the variable might hold. They are fundamental in exploring mathematical relationships, developing formulas, and problem-solving in algebra. By becoming comfortable with variable representation, we gain the flexibility needed to tackle a broad range of mathematical challenges."}]}]}]}}} 诪讬谞讬-诪讗诪专 3{
