Table of Questions and Answers

Question	Answer	Explanation	Difficulty Level
Simplify the expression: 2x + 3y 4x + 5y	-2x + 8y	Combine like terms: 2x 4x = 2x, 3y + 5y = 8y	Easy
Solve for x: 3x 5 = 10	x = 5	Add 5 to both sides of the equation: 3x 5 + 5 = 10 + 5, then divide both sides by 3 3x/3 = 15/3	Medium
Find the slope of the line passing through the points (2, 3) and (5, 7)	2	Use the slope formula: m = (y2 y1) / (x2 x1) = (7 3) / (5 2) = 4 / 3	Medium
Factor the polynomial: x^2 4x + 4	(x 2)^2	Use the difference of squares formula: a^2 b^2 = (a + b)(a b)	Easy
Solve the inequality: 2x 1 > 5	x > 3	Add 1 to both sides of the inequality: 2x 1 + 1 > 5 + 1, then divide both sides by 2 2x/2 > 6/2	Easy
Find the area of a circle with a radius of 5 cm	25π cm^2	Use the area formula for a circle: A = πr^2 = π(5 cm)^2	Easy

Find the mean of the following data set: 10, 12, 15, 18, 20	15	Add up all the numbers in the data set: 10 + 12 + 15 + 18 + 20 = 75. Divide the sum by the number of numbers in the data set 75 / 5 = 15.	Easy
Find the probability of rolling a 6 on a standard six-sided die	1/6	There are 6 possible outcomes when rolling a die, and only 1 of those outcomes is a 6.	Easy

Examples and Worked Solutions

This section provides a comprehensive collection of worked examples that illustrate the key concepts and techniques covered in Secondary Math 3 Module 1.

Example 1: Solving Linear Equations, Secondary math 3 module 1 answer key

• Problem:Solve the linear equation 2x + 5 = 13.

• Solution:
  

  Subtract 5 from both sides: 2x = 8

  Divide both sides by 2: x = 4

Example 2: Graphing Linear Equations

• Problem:Graph the linear equation y = 2x + 1.

• Solution:
  1. Find the y-intercept: (0, 1).
  2. Find another point on the line: (1, 3).
  3. Plot the two points and draw a straight line through them.

Example 3: Solving Systems of Equations

• Problem:Solve the system of equations:
  

  2x + y = 5x – y = 1

• Solution:
  

  Solve one equation for one variable (e.g., x = 1 + y).Substitute into the other equation: 2(1 + y) + y = 5. Solve for y: y = 1. Substitute y = 1 back into either equation to find x: x = 2.
