Question 1183595
 The sum of the two whole numbers is 45
x + y = 45
y = (45-x)
 and their difference is less than 10.
x - y < 10
x < y + 10
x < (45-x) + 10
2x < 55
x < 55/2
x < 27.5
x = 27
 The number of all possible pairs is???
x=27, y=18, a diff of 9
x=26, y=19, a diff of 7
x=25, y=20, a diff of 5
x=24, y=21, a diff of 3
x=23, y=22, a diff of 1
5 pairs possible with, using only positive number differences
