To find the sum of the first three prime numbers that end with a 9, you need to follow these steps:
1. Start with the number 19, which is the first prime number that ends with a 9.
2. Check if the number 19 is prime. Since it is, add it to your running sum.
3. Move to the next number that ends with a 9, which is 29.
4. Check if 29 is prime. If it is, add it to your running sum.
5. Continue to the next number that ends with a 9, which is 59.
6. Check if 59 is prime. If it is, add it to your running sum.
7. Calculate the sum of the three prime numbers to obtain your final answer.
So, the sum of the first three prime numbers that end with a 9 is 19 + 29 + 59 = 107.
