Answer 1

Step-by-step explanation:

1. a) 530-390=140. b)410-270=140
2. Q1) Express each of the following statements in algebraic form :
3. (i) The sum of 8 and x is equal to y.
4. (ii) x decreased by 5 is equal to y.
5. (iii) The sum of 2 and x is greater than y.
6. (iv) The sum of x and y is less than 24.
7. (v) 15 multiplied by m gives 3n.
8. (vi) Product of 8 and y is equal to 3x.
9. (vii) 30 divided by b is equal to p.
10. (viii) z decreased by 3x is equal to y.
11. (ix) 12 times of x is equal to 5z.
12. (x) 12 times of x is greater than 5z.
13. (xi) 12 times of x is less than 5z.
14. (xii) 3z subtracted from 45 is equal to y.
15. (xiii) 8x divided by y is equal to 2z.
16. (xiv) 7y subtracted from 5x gives 8z.
17. (xv) 7y decreased by 5x gives 8z.
19. Solution 1:
20. (i) 8 + x = y
21. (ii) x - 5 = y
22. (iii) 2 + x > y
23. (iv) x + y < 24
24. (v) 15 x m = 3n
25. (vi) 8 x y = 3x
26. (vii) 30 b = p
27. (viii) z - 3x = y
28. (ix) 12 x x = 5 z
29. (x) 12 x x > 5z
30. (xi) 12 x x < 5z
31. (xii) 45 - 3z = y
32. (xiii) 8x y = 2z
33. (xiv) 5x - 7y = 8z
34. (xv) 7y - 5x = 8z
