Answer 1

Please type your <u>subject</u> in the <b>School Subject</b> box. Any other words, <u>including obscure abbreviations</u>, are likely to delay responses from a teacher who knows that subject well.

Answer 2

Lets say the number is AB

so A+B=10

we also know that A<B

and both A and B are prime

so possibilities for A and B are

1,2,3,5,7

if A<B then A can only be 1,2,3,or 5

the only pairs such that A+B=10

are 55, 37

of these two only 37 is a prime number

But check the logic!
