Let (xi, yi), i = 1, 2, 3, 4, 5, be a set of five distinct points with integer coordinates in the xy plane. show that the midpoint of the line joining at least one pair of these points has integer coordinates.

yes. we do proportions in probabilities.

72 is the answer to this problem

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1

x=half
