Question

please solve correcyly​

Answer 1

Answer:

1. 4 : x :: x : 16

x² = 16 × 4

x² = 64

x = 8

2. 4x + 3x = 280

7x = 280

x = 40

4x = 40 × 4 = 160

3x = 40 × 3 = 120

3. Coefficient is 6 and -6 respectively

4. n + n + 2 + n + 4 = 3n + 6

5. 120 / 1440 × 100 = 25/3

6. x = 14 × 18/63

x = 4

7. a : c = 2 : 7

8. - 3/4 + x = 7/6

x = 7/6 + 3/4

x = 23/12

9. 5/6 + x = 13/18

x = 13/18 - 5/6

x = - 1/9

10. - 1/3 - x = - 1/2

- 1/3 + 1/2 = x

1/6 = x

11. 75 / 400 × 560 = 105 m

12. 4 days = 20 seconds

1 day = 5 seconds

7 days = 35 seconds....

Hope it helps you...
