We will dissect two intriguing problems, offering step-by-step explanations to enhance your understanding and problem-solving skills. Embark on this mathematical journey with us, where logic and precision intertwine to reveal the answers we seek.
Unraveling the Equation: Finding the Value of 'p'
Let's begin with our first challenge, an equation that beckons us to uncover the elusive value of 'p'. This problem is fundamental to understanding how mathematical expressions can be manipulated and simplified to isolate unknown variables. Mathematical equations are the backbone of quantitative disciplines, underpinning everything from basic arithmetic to advanced calculus. Grasping how to solve them effectively is essential for anyone aspiring to excel in mathematics and related fields.
We are presented with the equation (3.14 × 18) × 17.5 = 3.14 × (3p × 17.5) and tasked with finding the value of 'p'. This equation exemplifies the associative property of multiplication, which states that the grouping of factors does not affect the product. By understanding and applying this property, we can strategically rearrange the equation to simplify it and isolate 'p'. The associative property is a cornerstone of mathematical manipulation, allowing us to reorder and regroup terms without altering the equation's fundamental truth. This is crucial for simplifying complex expressions and making them easier to solve.
The key to solving this equation lies in recognizing the common factors on both sides. Notice that 3.14 and 17.5 appear on both sides of the equation. This observation allows us to simplify the equation significantly. We can divide both sides of the equation by these common factors, reducing the complexity and bringing us closer to isolating 'p'. This strategy of identifying and canceling common factors is a powerful technique in algebra, enabling us to reduce complex equations to simpler, more manageable forms. It is a technique that students will encounter frequently in their mathematical studies and is essential for efficient problem-solving.
Dividing both sides by 3.14 and 17.5, we get:
(3.14 × 18) × 17.5 / (3.14 × 17.5) = 3.14 × (3p × 17.5) / (3.14 × 17.5)
This simplifies to:
18 = 3p
Now, we have a much simpler equation to solve for 'p'. To isolate 'p', we divide both sides of the equation by 3:
18 / 3 = 3p / 3
This yields:
6 = p
Therefore, the value of p is 6.0, which corresponds to option C. This methodical approach demonstrates the power of simplification in mathematics. By systematically reducing the complexity of the equation, we were able to isolate the unknown variable and determine its value with ease. This is a fundamental skill that is applicable across various mathematical disciplines.
The Age-Old Puzzle: Solving for the Son's Age
Now, let's turn our attention to the second problem, an age-related puzzle that requires us to use algebraic reasoning to determine the son's current age. Age problems are a classic staple of mathematical puzzles, often requiring the translation of word problems into algebraic equations. They are a great way to develop critical thinking and problem-solving skills, as they demand careful reading, logical deduction, and the ability to represent relationships between quantities using variables.
The problem states: “A man was 24 years old when his son was born. Now he is three times as old as his son. Find the age of the son.” This problem presents a relationship between the ages of the father and the son, both at the time of the son's birth and at the present time. To solve this, we need to translate the given information into algebraic equations that capture these relationships. The key to solving age problems is to identify the variables involved (in this case, the ages of the father and son) and to express the given information in terms of these variables. By carefully setting up the equations, we can then use algebraic techniques to solve for the unknown quantities.
Let's represent the son's current age as 'x'. Since the man was 24 years old when his son was born, the man's current age is x + 24. The problem also states that the man is currently three times as old as his son. This gives us the equation:
x + 24 = 3x
This equation beautifully encapsulates the relationships described in the problem. The left side (x + 24) represents the man's current age, expressed in terms of the son's age, while the right side (3x) represents the man's age as three times the son's age. By setting these two expressions equal to each other, we have created an algebraic equation that we can solve for the unknown variable 'x'.
To solve for x, we first subtract x from both sides of the equation:
x + 24 - x = 3x - x
This simplifies to:
24 = 2x
Next, we divide both sides of the equation by 2 to isolate x:
24 / 2 = 2x / 2
This yields:
12 = x
Therefore, the son's current age is 12 years old. This solution demonstrates the power of algebra in solving real-world problems. By translating the word problem into algebraic equations, we were able to systematically solve for the unknown age. This is a valuable skill that can be applied to a wide range of problem-solving scenarios.
In this exploration of mathematical equations and age puzzles, we have demonstrated the importance of understanding fundamental mathematical principles and applying them strategically to solve problems. From simplifying equations by identifying common factors to translating word problems into algebraic expressions, these techniques are essential for success in mathematics and beyond. By mastering these skills, you will be well-equipped to tackle a wide range of mathematical challenges with confidence and precision.
By diligently practicing and applying these problem-solving strategies, you can develop a deeper understanding of mathematical concepts and enhance your ability to approach complex problems with clarity and efficiency. Remember, mathematics is not just about memorizing formulas; it is about developing logical reasoning and critical thinking skills that can be applied in various aspects of life. So, embrace the challenge, explore the world of mathematics, and unlock your full potential.
