For this case what we can do is the following rule of three: 2/3 of a box ------> 1/2 minutes x of a box ---------> 1 minute Clearing x we have: x = (1 / (1/2)) * (2/3) Rewriting: x = 2 * (2/3) x = 4/3 Answer: the number of boxes per minute that the machine packs is: x = 4/3
You would add 5 and 17 and that would equal 22 Now it would be 22=J-14 Then add 14 on both sides so it cancels out 22 plus 14 is 36 So J would equal 36
