ok so this is a little hard umm... the 10th prime number is let's see: 1,2,3,5,7,11,13,17,19,23 <------ 23 And the 10th composite number is: 4,6,8,9,10,12,14,15,16,18<------- 18 SO 23 plus 18 ISSSSSS........... 41 So the sum of the 10th prime number and the 10th composite number is 41!!! * * * * * 1 is neither prime nor composite. So the tenth prime is actually 29 and the sum is 47.
It is: 28
184 is composite. 184 = 2 * 2 * 2 * 23 = 23 * 23
Not all numbers between 20 and 28 are composite numbers. 23 is a prime number.
69 is a composite number because it is a multiple of 3 and 23.
15 is composite number 17, 19 and 23 are prime numbers.
23?

Just add them together but leaving out 17, 19, 23 and 29 which are prime numbers
