Understanding the Problem
In this problem, we are given a statement that involves a mathematical equation. The statement is: "Negative 3 less than 4.9 times a number, {x$}$, is the same as 12.8." We need to select the correct equation that accurately represents this statement.
Breaking Down the Statement
Let's break down the statement into smaller parts to understand it better.
- "Negative 3 less than" means we need to subtract 3 from the result of the multiplication.
- "4.9 times a number, {x$}$," means we need to multiply 4.9 by the number {x$}$.
- "is the same as 12.8" means the result of the subtraction should be equal to 12.8.
Analyzing the Options
Now, let's analyze the three options given:
Option A: {-3 - 4.9x = 12.8$}$
This option represents the statement as: "Negative 3 less than 4.9 times a number, {x$}$, is the same as 12.8." It correctly represents the statement by subtracting 3 from the result of the multiplication.
Option B: ${4.9x - (-3) = 12.8\$}
This option represents the statement as: "4.9 times a number, {x$}$, minus negative 3 is the same as 12.8." However, this option does not accurately represent the statement because it does not correctly represent the subtraction of 3.
Option C: ${3 + 4.9x = 12.8\$}
This option represents the statement as: "3 plus 4.9 times a number, {x$}$, is the same as 12.8." However, this option does not accurately represent the statement because it does not correctly represent the subtraction of 3.
Conclusion
Based on the analysis of the options, the correct equation that accurately represents the statement is:
Option A: {-3 - 4.9x = 12.8$}$
This equation correctly represents the statement by subtracting 3 from the result of the multiplication.
