Since the sum of the integers is 35, the average is 35/5 = 7, So the "middle" integer should be near 7. Since 5 + 6 + 7 + 8 + 9 =35, the five integers are 5, 6, 7, 8, and 9, 6 and 8 are not primes because they are divisible by 2:9 is not a prime since it is divisible by 3. Only 5 and 7 are primes. So two of the five integers are primes
