Understanding the Problem

In mathematics, a translation is a transformation that moves a point or a figure from one location to another without changing its size or shape. When it comes to equations, a translation can be represented by rearranging the terms or changing the order of operations. In this article, we will explore which equation is a translation of the given sentence: "Three plus ${$ d $}$ equals 120 times ${$ f $}$."

The Given Sentence

The given sentence is: "Three plus ${$ d $}$ equals 120 times ${$ f $}$."

To understand this sentence, let's break it down into its individual components:

"Three" represents a constant value of 3.
"plus" indicates addition.
" ${$ d $}$" represents a variable value, which we can assume to be a single variable, d.
"equals" indicates that the result of the addition is equal to the result of the multiplication.
"120 times" indicates multiplication by 120.
" ${$ f $}$" represents another variable value, which we can assume to be a single variable, f.

Analyzing the Options

Now, let's analyze each of the given options to determine which one is a translation of the given sentence:

Option A: ${$ 3 + d = 120f $}$

This option represents the original equation, where 3 is added to d and the result is set equal to 120 times f. This is a direct translation of the given sentence.

Option B: ${$ 3d + 120f $}$

This option represents a different equation, where 3 times d is added to 120 times f. This is not a translation of the given sentence, as it changes the order of operations and combines the terms in a different way.

Option C: ${$ 3 = d + 120f $}$

This option represents an equation where 3 is set equal to the result of adding d and 120 times f. This is not a translation of the given sentence, as it changes the order of operations and reverses the equality.

Option D: ${$ 3d = 120f $}$

This option represents an equation where 3 times d is set equal to 120 times f. This is not a translation of the given sentence, as it changes the order of operations and combines the terms in a different way.

Conclusion

Based on the analysis of each option, we can conclude that the correct answer is:

Option A: ${$ 3 + d = 120f $}$

This option represents a direct translation of the given sentence, where 3 is added to d and the result is set equal to 120 times f.

Understanding Translations in Mathematics

Translations in mathematics are an essential concept in algebra and geometry. They help us understand how to manipulate equations and expressions to solve problems. In this article, we have explored how to identify a translation of a given sentence, and we have seen that it requires careful analysis of the individual components of the sentence.

Common Types of Translations

There are several types of translations that we can perform on equations and expressions, including:

Rearranging terms: This involves changing the order of the terms in an equation or expression.
Changing the order of operations: This involves changing the order in which we perform operations such as addition, subtraction, multiplication, and division.
Combining like terms: This involves combining terms that have the same variable or constant.

Examples of Translations

Here are some examples of translations that we can perform on equations and expressions:

Rearranging terms: The equation 2x + 3y = 5 can be rearranged to 3y = 5 - 2x.
Changing the order of operations: The equation 2x + 3y = 5 can be rewritten as (2x + 3y) = 5.
Combining like terms: The equation 2x + 3y + 2x = 5 can be simplified to 4x + 3y = 5.

Real-World Applications of Translations

Translations have many real-world applications in fields such as science, engineering, and economics. For example:

Physics: Translations are used to describe the motion of objects in terms of their position, velocity, and acceleration.
Engineering: Translations are used to design and optimize systems such as electrical circuits, mechanical systems, and computer networks.
Economics: Translations are used to model economic systems and make predictions about future trends and outcomes.
