Answer:

  • Q6. x = 17
  • Q8. Yes, parallel
  • Q9. No, not parallel

Step-by-step explanation:

Q6. Solve for x

<u>Use ratios of similar sides</u>

  • 28/(82 - 28) = (2x + 8)/(5x - 4)
  • 28/54 = (2x + 8)/(5x - 4)
  • 14/27 = (2x + 8)/(5x - 4)
  • 14(5x - 4) = 27(2x + 8)
  • 70x - 56 = 54x + 216
  • 70x - 54x = 56 + 216
  • 16x = 272
  • x = 272/16
  • x = 17

Q8

If ratios are same, the lines are parallel

  • 41.8/33 = (102 - 45)/45
  • 41.8/33 = 57/45
  • 41.8*45 = 33*57
  • 1881 = 1881

Yes, lines are parallel

Q9

  • 38/19 = 52/24
  • 2 = 2 1/3

Incorrect, lines are not parallel

How do I solve this arithmetic sequence?
Sveta_85 [38]

Answer:

The 16ᵗʰ term of this sequence is 82

Step-by-step explanation:

Here,

First Term = a₁ = 9

Common Difference = (d) = 2

Now, For 16ᵗʰ term, n = 16

<em>aₙ = a + (n - 1)d</em>

a₁₆ = 7 + (16 - 1) × 2

a₁₆ = 7 + 15 × 5

a₁₆ = 7 + 75

a₁₆ = 82

Thus, The 16ᵗʰ term of this sequence is 82
