Answers are 1. a = 32, b = 2, 3. c = 4, 4. x = -3, 5. y = -7, 6. z = -2, 7. m = -7, 8. n = -4, 9. s = -3, 10. r = 5, 11. t = 3, 12. p = 2, 13. x = 9, 14. w = 6, 15. g = 1.5, 16. v = -16, 17. b = -6, 18. h = -5, 19. k = -2.5, 20. d = -3.5, 21. r = -8, 22. z = -9, 23. x = -7, 24. y = 3.5, 25. y = 9, 26. w = 8.
Step-by-step explanation:
Step 1; To solve the given equations we keep the unknown variable on one side while the known numbers are taken to the other side. If both sides are negative the answer has a positive value while if one side is positive and one side is negative, the answer is negative.
Step 2; Solve
1. a = 9/3= 3,
2. b = 14/7 = 2,
3. c = 36/9 = 4,
4. x = -15/5 = -3,
5. y = 28/-4 = -7,
6. z = -16/8 = -2,
7. m = 28/-4 = -7,
8. n = 8/-2 = -4,
9. s = -21/7 = -3,
10. r = -25/-5 = 5,
11. t = -18/-6 = 3,
12. p = -18/-9 = 2,
13. x = 18/2 = 9,
14. w = 24/4 = 6,
15. g = 9/6 = 1.5,
16. v = -32/2 = -16,
17. b = -18/3 = -6,
18. h = -35/7 = -5,
19. k = 20/-8 = -2.5,
20. d = 14/-4 = -3.5,
21. r = -72/9 = -8,
22. z = 27/-3 = -9,
23. x = -35/5 = -7,
24. y = 28/8 = 3.5,
25. y = 81/9 = 9,
26. w = 16/2 = 8.
7 packages will have 6 cupcakes each and the for 5 of the packages there will be 6 cupcakes in them.
4x² + 23x = -28
4x² + 23x + 28 = 0 move all terms to one side.
4x² + 16x + 7x + 28 = 0 split the second term into two terms
4x(x + 4) + 7(x + 4) = 0 factor.
(x + 4)(4x + 7) = 0 factor.
x = -4, -7/4
hope this helps, God bless!
