Lana has 3 bags with the same amount of marbles in them, totaling 12 marbles. Markus has 3 bags with the same amount of marbles in them, totaling 18 marbles. How many more marbles does Markus have in each bag?
Starting with Lana, if she has 3 bags and a total of 12 marbles you would have to evenly divide her marbles between her bags which would leave her with 4 marbles in each bag. because 12 divided by 3 is 4. Markus has 3 bags and a total of 18 marbles with even amount in each bag. Same as Lana, you would have to evenly divide his marbles between his bags which would leave him with 6 marbles in each bag because 18 divided by 3 = 6. Now if markus has 6 in each bag and Lana has 4 in each bag you would subtract 6 from 4 in order to see how many more marbles he has in his bags (6-4) which equal 2. The answer: Markus has 2 more marbles in each bag than Lana. Another way you can do this problem is if markus has 18 marbles total and lana has 12 marbles total but they are both divided into evenly into 3 bags you can subtract the difference between the marbles (18-12 =6) which would mean Markus has a total of 6 marbles more than Lana. But you have to divide it by the amount of bags , which is 3 so you would divide 6 by 3 which would give you a total of 2. (6/3 = 2) The answer: Markus has 2 more marbles in each bag than Lana.
2(3-h) - 6= -5h
2(3-h) - 6= -5h [do the parathesis first, 2 x 3 = 6 and 2 x -h = -2h] 6-2h - 6 = -5h [put the variable on the same side, in this case you would add 2h to both sides] 6- 6 = -3h [ do the math on the left which equals 0] 0= -3h [the next step would be to divide -3 on both sides to get h by itself, since the left is 0, the answer would be 0] 0 = h
