The weight of one bag of groceries is 9 12/13 pounds. A second bag of groceries weighs 9 21/26. How many pounds more does the heavier bag weigh?

18 9/13

Step-by-step explanation: First we would have to make 9 21/26 into a improper fraction, which would be 255/26. I did 9*26=234, then I did 234+21=255. So now we have 255/26 - 12/13. We now have to find a number that both can divide by, which would be 13. So, we leave 12/13 just as is, then we do 255/26 / 1/2 which would be multiplying by it’s recriprical, so 255/26 * 2/1. Which would be 255/13. Now we can subtract 255/13 - 12/13. 255 - 12 = 243, so our answer would be 243/13. 243/13 = 18 9/13. (Sorry if I am incorrect)

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
