The smallest mass of sugar for which that will be possible will be <u>30.5g.</u>
Since we're given the information that each heap contains either 27g, 45g, 30g, or 20g, then in order to calculate the smallest mass of sugar that can be divided to get equal heaps, we've to find the average of the numbers given and this will be:
The answer is (5,3). You need to equal both sides out. So 5x-22=4x-17. That will give you x=5. After that you substitute 5 for x in one or both of the equations and get that y=3. Hope this helps!
