... times a number. Again, ask yourself “The sum of what?” That is the sum of 3x + 10. The subtracted from is very important here. Since it is stated this way, we are subtracting the first part “from” the second part or 9x – (3x + 10). Why did a put the 3x+10 in parentheses? Because the problem states t ...

... 6. (2006 AMC 12A Problem 12) A number of linked rings, each 1 cm thick, are hanging on a peg. The top ring has an outside diameter of 20 cm. The outside diameter of each of the outer rings is 1 cm less than that of the ring above it. The bottom ring has an outside diameter of 3 cm. What is the dista ...
