How do you get the mass of the entire sample?

It's 37.9 grams of SO2

Okay thanks. I worked it out and got the correct answer of 86.8 grams for the mass product.

All you have to do is multiply parts of the 2500 by .08 and .12 then find which amount is the same. EXP 1250 * .08 = 100 1250 * .12 = 150 since those don't match go to 1300*.08 and 1200*.12 and so on untill you find the same answer

would you really have to multiply .08 and .12 by 100 or could you leave it the way it is?

I think it would be x+y=56

I think it would be x+3x=56

because now you have 3x=y

I don't think so The second part is giving you a way to solve the problem. so if you find out whay y is then you can find out what x is.

x+y=56 x+3x=56 56/4= 14 x=14 56-14=42 y=42 check 14+42=56 or 14+(14*3)=56

I guess you could write it x+y=56 4x=56 56/4=x x=14 14+y=56 56-14=y y=52 I'm not sure how your teacher would want you to show your work. This way might be the simplest form

well the 4 came because it says y = 3 times as many as x so for y to be 3 times as many as x there has to be 4 parts of 56 1 part is x and the remaining 3 are y. Does that help?

I see well think you for showing me an easier and faster way to figure that problem out. I was taught the long way on most math problems.

I think this is right but I'm not sure on this part of your problem. from part a, x + y = 56, then at x = 0, y = 56. Therefore y-intercept = 56 at y = 0, x = 56. Therefore x-intercept = 56 from part b, y = 3x, then This is a straight line, passing through...

Sorry this is the answer to the 2nd question. Using the straight lines x + y = 56 and y = 3x, then they would intersect at x = 14 and y = 42

YES PART A IS RIGHT WHAT DID YOU GET FOR PART B OF QUESTION 2

yes that's right and part c and then question 3

Part C is just as it says using elimination to get the right answer. I found it faster if you just use the first numbers exp 175*2=350 so, 7200-350=6850 well you know that 200 will not go into 6850 evening so you keep going 175*3=525 7200-525=6675 200 wil...

The numbers M and N are different numbers selected from the first 25 counting numbers: If M is larger than N, what is the smallest value that the expression below can have? m * n over m-n?

I thought in this problem M and N had to be the same numbers so how could we do 1*2 over 25-1. Also, M has to be larger than N........still confused.

Sue, are you able to help? My son has to go to bed soon and we are anxious to figure out how to do this....appreciate your help!!!
