Question

Solve the proportions:

Answer 1

Answer:

• 6. 6.75
• 7. 27
• 8. 92/17
• 9. 49

Step-by-step 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.
