Key Questions and Solutions from the November 2012 Paper

Below, we will analyze some representative questions from the exam, providing detailed solutions and explanations to help students understand the problem-solving process.

Question 1: Simplifying Algebraic Expressions

Question: Simplify the expression \(3x + 5x - 2x + 7\).

Answer and Explanation:

To simplify, combine like terms:

• \(3x + 5x - 2x = (3 + 5 - 2)x = 6x\)
• The constant term remains as 7

Simplified expression:

\[

6x + 7

\]

Tip: Always group like terms carefully and perform addition or subtraction accordingly.

Question 2: Calculating the Area of a Rectangle

Question: A rectangle has a length of 12 cm and a width of 5 cm. Find its area.

Solution:

• Area of a rectangle = length × width
• \(12 \text{ cm} \times 5 \text{ cm} = 60 \text{ cm}^2\)

Answer:

\[

\boxed{60\, \text{cm}^2}

\]

Tip: Remember to label units clearly and double-check measurements before calculating.

Question 3: Solving a Linear Equation

Question: Solve for \(x\): \(2x + 3 = 11\).

Solution:

• Subtract 3 from both sides:

\(2x = 11 - 3 = 8\)

• Divide both sides by 2:

\(x = \frac{8}{2} = 4\)

Answer:

\[

\boxed{4}

\]

Tip: Always perform inverse operations step-by-step to avoid mistakes.

Question 4: Working with Percentages

Question: A shirt originally costs £20. During a sale, it is discounted by 25%. What is the sale price?

Solution:

• Find 25% of £20:

\(25\% \times 20 = \frac{25}{100} \times 20 = 0.25 \times 20 = 5\)

• Subtract the discount from the original price:

\(20 - 5 = £15\)

Answer:

\[

\boxed{£15}

\]

Tip: Converting percentages to decimals makes calculations straightforward.
