Solve the proportions:

6. 9/16 = x/12

7. x-3/18 = 12/9

8. 17/15 = 10/2x-2

9. x-16/x+6 = 3/5

Solve the proportions: 6. 9/16 = x/12 7. x-3/18 = 12/9 8. 17/15 = 10/2x-2 9. x-16/x-example-1

Answer:

  • 6. 6.75
  • 7. 27
  • 8. 92/17
  • 9. 49

Explanation:

- Question 6 -

  • 9/16 = x/12
  • => 16x = 12 x 9
  • => 16x = 108
  • => x = 6.75

Hence, the value of x in this proportion is 6.75.

- Question 7 -

  • -3 + x/18 = 12/9
  • => -3/18 + x/18 = 4/3
  • => x/18 = 4/3 + 1/6
  • => x/18 = 8/6 + 1/6
  • => x/18 = 9/6
  • => x = 9/6 x 18
  • => x = 27

Hence, the value of x is 27

_______________________________

- Question 8 -

17/15 = 10/2x - 2

=> 17(2x - 2) = 150

=> 34x - 34 = 150

=> 34x = 184

=> x = 184/34

=> x = 92/17

Hence, the value of x is 92/17

_______________________________

- Question 9 -

  • x - 16/x + 6 = 3/5
  • => 5(x - 16) = 3(x + 6)
  • => 5x - 80 = 3x + 18
  • => 2x = 98
  • => x = 49

Hence, the value of x is 49.
