To solve this problem, do this...
There are 10 numbers, so the first term of the expression is 2^10. Then subtract that by 2^9 to find the answer.
2^10 = 1024
2^9 = 512
1024-512 = 512
There are 512 subsets that do not contain the number 5.

Very Good!!!
Thank You, doorknoob!!
If 1:6, 12:x?
12/1 = 12.
12*6 = 72
The answer is 72 meters.
An equivalent for dividing by 2 is multiplying by 1/2 or .50.
The rule is add 4.
999-100 = 899
899+1 = 900
There are 900 three-digit positive numbers.
3(x+5) Multiply 3 by the x and 5 respectively.
That would be 3x+15.
11:38 A.M. + 1 hr = 12:38 P.M.
12:38 P.M. - 30 min = 12:08 P.M.
12:08 P.M. is the answer.
8*8 = 64* 1!
