Understanding the Importance of Independent Practice

Independent practice is a crucial element of the learning process. It allows students to solidify their understanding of concepts learned in class by applying them to new problems. This self-directed practice fosters critical thinking, problem-solving skills, and independent learning habits – essential skills that extend far beyond the classroom. Regularly completing independent practice exercises helps identify areas where further clarification or review may be needed, enabling students to address knowledge gaps proactively.

This "5.2 Independent Practice" section likely builds upon concepts covered in section 5.1. Therefore, it's crucial to have a strong understanding of the foundational material before tackling these problems. Reviewing notes, examples, and potentially seeking clarification from teachers or peers before starting independent practice can significantly improve comprehension and success rates.

Detailed Solutions and Explanations

Now, let's work through each problem step-by-step, providing detailed explanations to aid understanding.

1. Solve for x: 3x + 7 = 16

• Step 1: Subtract 7 from both sides: 3x = 9
• Step 2: Divide both sides by 3: x = 3
• Answer: x = 3

2. Solve for y: 5y - 12 = 23

• Step 1: Add 12 to both sides: 5y = 35
• Step 2: Divide both sides by 5: y = 7
• Answer: y = 7

3. Solve for z: (z/4) + 6 = 10

• Step 1: Subtract 6 from both sides: z/4 = 4
• Step 2: Multiply both sides by 4: z = 16
• Answer: z = 16

4. Solve the inequality: 2x - 5 > 9

• Step 1: Add 5 to both sides: 2x > 14
• Step 2: Divide both sides by 2: x > 7
• Answer: x > 7

5. Solve the inequality: -3x + 1 ≤ 7

• Step 1: Subtract 1 from both sides: -3x ≤ 6
• Step 2: Divide both sides by -3 (remember to flip the inequality sign): x ≥ -2
• Answer: x ≥ -2

6. Solve for a: 2(a + 3) = 14

• Step 1: Distribute the 2: 2a + 6 = 14
• Step 2: Subtract 6 from both sides: 2a = 8
• Step 3: Divide both sides by 2: a = 4
• Answer: a = 4

7. Solve for b: 3(b - 5) + 7 = 10

• Step 1: Distribute the 3: 3b - 15 + 7 = 10
• Step 2: Simplify: 3b - 8 = 10
• Step 3: Add 8 to both sides: 3b = 18
• Step 4: Divide both sides by 3: b = 6
• Answer: b = 6

8. A rectangular garden has a length of (x + 5) meters and a width of 3 meters. If the area of the garden is 30 square meters, what is the value of x?

• Step 1: Write the equation for the area of a rectangle: Area = Length × Width
• Step 2: Substitute the given values: 30 = (x + 5) × 3
• Step 3: Divide both sides by 3: 10 = x + 5
• Step 4: Subtract 5 from both sides: x = 5
• Answer: x = 5

9. Sarah has $25. She wants to buy a book that costs $12 and some candies that cost $1 each. Write an inequality to represent the maximum number of candies (c) she can buy. Then solve for c.

• Step 1: Write the inequality: 12 + c ≤ 25
• Step 2: Subtract 12 from both sides: c ≤ 13
• Answer: Sarah can buy a maximum of 13 candies (c ≤ 13).

10. The sum of two consecutive integers is 27. What are the two integers?

• Step 1: Let the first integer be x. The next consecutive integer is x + 1.
• Step 2: Write the equation: x + (x + 1) = 27
• Step 3: Simplify and solve: 2x + 1 = 27 => 2x = 26 => x = 13
• Step 4: Find the next integer: x + 1 = 14
• Answer: The two consecutive integers are 13 and 14.
