Solving math word problem
Okay, now I'm going to just rewrite what we know. We know that the first pole plus the second low equals 48. The second rule plus the third bowl equals 34 third rule plus the fourth bowl equals 30. And the fourth bowl plus the 5th bowl equals 48. So like I said, everywhere else you see, I'm gonna put the number four. So here, and here, I'm gonna put four and four. So B plus four gives us 34. If we're going to this direction, we add, we can also work backwards. And subtract. So 34 minus four gives us 30.
So I know that B has to be 30. 30 plus four is 34. So everywhere I see a B, I'm going to put 30. So now I need 30 plus and number to give me 48. Going this way is addition. We can go backwards, which is subtraction. So I have 48 -30. Which gives me 18. So that means a has to be 18. So it's 18 plus 30, 48. Yes it is. So that's correct. Let's go here. We have four plus the numbers you give me 30, or again, we can work backwards and do 30 minus four. I have $0. I can give you four. So I'm going to go next door, borrow one, which makes that two, the one that I borrow, stick it right here in front of that number. So now I have ten minus four gives me 6, bring down my two so that means D has to be 26. So I'm going to put 26 here for D 26 plus this number gives me 48.
If I'm going this direction, I can add if I'm working backwards, I can go ahead and subtract these two numbers of 48 -26. So E has to be 22. So I'm going to go over here to my answers. And I'm going to put a little a has 18 nuts. Bowl B has 30 full C has four D has 26. And E has 22. Now I'm going to make sure that this is correct. Before I move on. So all 5 of these should add up and give me 100. So we have 8 plus two is ten. Plus 6 more 16, 16 plus four is 20. You put a zero, carry the two here. You have two, four, 6, plus four is ten. So that is correct. These are my answers. That's it. Thank you very much.
