Five people have just won a $100 prize, and are deciding how to divide the $100 up between them. Assume that whole dollars are used, not cents. Also, for example, giving $50 to first person and $10 to the second is different from vice versa.

Combine terms: 12a + 26b - 4b - 16a. (a) 4a + 22b, (b) - 28a + 30b, (c) - 4a + 22b, (d) 28a + 30b. Solution: 12a + 26b - 4b - 16a. = 12a - 16a + 26b - 4b. = - 4a + 22b.

Sue wrote the number 43,671. jack also wrote a 5 digit number. Jack's number has only one 3 in it. the 3 in jack's number is worth 10 times as much as the 3 in sue's number. write two different numbers that jack could have written.
