19. 200 gram mass13 marbles Chappell I see a bag hanging down from a bar. The string is hanging at 18. 10*200 x 13X = 26000x 10*200 2000 = 13X 13 = 13

20. 200 gram mass 13 marbles Jamel (200)(10) = (18) + 13 X

21. 200 gram mass 13 marbles Duree (200)(10) = (18)(13 X) 2000234

22. 200 gram mass 13 marbles Duree (200)(10) = (18)(13 X) 2000234X 234 = 234

23. 200 gram mass 13 marbles Duree (200)(10) = (18)(13 X) 8.55 = X

24. Kim 400 grams200 grams and 6 marbles (400)(19) = (30)(25 + 6x) 7600 = 6000 + 180 X 6000 = 6000 1600 =180 X

25. Kim 400 grams200 grams and 6 marbles 1600 = 180X 180 = 180 8.89 = X
