Problem #1 Week 5 BY: Alexis Rapach :P
2
Problem My number is 3 fewer than the sum of A and B. A is the smallest positive multiple of 13 for which the sum of its digits is prime. B is twice the value of the Roman numeral DXLIX. What is my number?
3
Step 1 First I found the roman numeral DXLIX. It was 549 so I had to double it so now I have 1098. 549 + 549 1098
4
Step 2 Then after I found the roman numeral I had to find the smallest positive multiple and it had to be prime. So I started with the smallest multiple of 13 and continue with the next smallest until finding one that fits the problem. 1)13} 1 + 3 = 4 which is not prime 2)26} 2 + 6 = 8 which is not prime 3)39} 3 + 9 = 12 which is not prime 4)52} 5 + 2 = 7 which is prime
5
Step 3 3 less After I found the Roman Numeral and the smallest positive multiple of 13 that’s prime, I added them together; 1098 + 52 = 1150 and in the problem if you read it says 3 less than the sum of A and B. And if the sum for A is 52 and the sum for B is 1098 and they equal 1150 together than I need to subtract 3 from 1150 and I get; 1150 – 3 = 1147
