Question

2n - 4 * 90 * 2 = 360 * 3 - 4marks

Answer 1

Given

• 2n - 4 × 90 × 2 = 360 × 3

To find

• n

Solution

• 2n - 4 × 90 × 2 = 360 × 3
• 2n - 4 × 180 = 1080
• 2n - 4 = ¹⁰⁸⁰⁄₁₈₀
• 2n - 4 = ⁶⁄₁
• 2n - 4 = 6
• 2n = 6 + 4
• 2n = 10
• n = ¹⁰⁄₂
• n = 5

↦ The value of n is 5

Answer 2

2n - 4 × 90 × 2 = 360 × 3

2n - 4 × 180 = 1080

2n - 4 = ¹⁰⁸⁰⁄₁₈₀

2n - 4 = ⁶⁄₁

2n - 4 = 6

2n = 6 + 4

2n = 10

n = ¹⁰⁄₂

n = 5
