Answered by Ms. Sue
These are the prime numbers between 30 and 60

31, 37, 41, 43, 47, 53, 59

Which one of those meets the other criterion?
Answered by henry2,
tens digit = X.
ones digit = x - 3.

10x + (x-3) = 11x - 3 = the number.
30 < 11x-3 < 60.
33 < 11x < 63,
3 < x < 5 8/11.
X = 4 or 5.
Let x = 4.

11x - 3 = 11*4 - 3 = 41 = the prime number between 30 and 60.
