To find the pairs of whole numbers that sum to 110, we can express one number as ( x ) and the other as ( 110 - x ). The pairs are formed by choosing different whole number values for ( x ) from 0 to 110. This results in a total of 111 pairs, including (0, 110) and (110, 0), as well as all combinations in between. Thus, there are 111 pairs of whole numbers that sum to 110.
3 pairs of whole numbers add up to 7: 1 +6, 2+5, 3+4 (0+7 also equals 7, but zero is not a whole number)

To find the pairs of whole numbers that sum to 110, we can express the pairs as (x, 110 - x), where x is a whole number. The values of x can range from 0 to 110, giving us a total of 111 pairs, including (0, 110) and (110, 0). However, each pair (x, 110 - x) is considered the same as (110 - x, x), so we actually have 56 unique pairs, plus the pair (55, 55) when x equals 55.
To find the sum of the products of two different whole numbers that equal 7, we can identify the pairs of whole numbers whose product is 7. The pairs are (1, 7) and (7, 1), as well as (7, 1) and (1, 7) again. The product of each pair is 7, and since they are the same, the sum of these products remains 7. Therefore, the answer is 7.
There 4 pairs of primes that can give a sum 40 in addition. They are (3,37), (11,29), (17,23),(19,21).
