The Product of Two Numbers: A Mathematical Equation

Understanding the Problem

In this problem, we are given two pieces of information: the product of two numbers is 450, and the first number is half the second number. We need to find the equation that can be used to find $x$ , the greater number. To solve this problem, we need to use algebraic equations and mathematical reasoning.

Breaking Down the Information

Let's break down the information given in the problem:

The product of two numbers is 450. This can be represented as $xy = 450$ , where $x$ and $y$ are the two numbers.
The first number is half the second number. This can be represented as $x = \frac{1}{2}y$ .

Finding the Equation

We can use the second piece of information to substitute $x$ in the first equation. Since $x = \frac{1}{2}y$ , we can substitute this expression for $x$ in the first equation:

\frac{1}{2}y \cdot y = 450

Simplifying this equation, we get:

\frac{1}{2}y^2 = 450

Multiplying both sides of the equation by 2, we get:

y^2 = 900

Since $x = \frac{1}{2}y$ , we can substitute this expression for $y$ in the equation:

x^2 = 900

Choosing the Correct Equation

Now that we have found the equation, we need to choose the correct answer from the options given. Let's analyze each option:

A. $\frac{1}{2} x^2 = 450$ - This equation is not correct, as we have found that $x^2 = 900$ , not $\frac{1}{2} x^2 = 450$ .

B. $225 x^2 = 0$ - This equation is not correct, as we have found that $x^2 = 900$ , not $225 x^2 = 0$ .

C. $x^2 = 450$ - This equation is not correct, as we have found that $x^2 = 900$ , not $x^2 = 450$ .

D. $450 x^2 = 0$ - This equation is not correct, as we have found that $x^2 = 900$ , not $450 x^2 = 0$ .

However, we can rewrite the equation $x^2 = 900$ as $\frac{1}{2} x^2 = 450$ by multiplying both sides of the equation by $\frac{1}{2}$ . Therefore, the correct answer is:

A. $\frac{1}{2} x^2 = 450$

Conclusion

In this problem, we were given two pieces of information: the product of two numbers is 450, and the first number is half the second number. We used algebraic equations and mathematical reasoning to find the equation that can be used to find $x$ , the greater number. The correct answer is $\frac{1}{2} x^2 = 450$ .
