This equation has no solution:
-15y+7+17y=2y+70
2y+7=2y+70
7≠70
Often, rulers are not labeled. Rather, the marks change length according to the fraction they represent. One mark greater than 7/16 is 8/16. It will be the longest mark, halfway between the integer marks, so will represent 1/2.

13 x 3 = 39
39 + 17 = 56
56 / 8 = 7
Hope this helps :)
There are 13 sets of 4 cards in a deck of card. So, there are 13 ways to get four cards of the same face value. The next card you pick will always be a different face value. So, essentially, you have 13 x 48 combinations of 5 cards that you can pick from the deck where you have 4 cards of the same face value and 1 card of a different face value.
13 x 48 = 624.
