Question

10,14,16,18,20 plz I don't understand

Answer 1

10. b - 16.6 = -3.7.....add 16.6 to both sides
b - 16.6 + 16.6 = -3.7 + 16.6
b = -3.7 + 16.6
b = 12.9

14. 18.91 = -7.9 + x.....add 7.9 to both sides
18.91 + 7.9 = -7.9 + 7.9 + x
26.81 = x

16. 295.8997 = -10.1k....divide both sides by -10.1
295.8997 / -10.1 = (-10.1/-10.1)k
- 29.297 = k

18. -94.4724 = 3.3x....divide both sides by 3.3
- 94.4724 / 3.3 = (3.3 / 3.3)x
- 28.628 = x

20. -29.4x = -148.764...divide both sides by -29.4
(-29.4 / -29.4)x = - 148.764 / -29.4
x = 5.06
