Bom thinks that "if a>b and c>d , then a+d>b+c" to point out that the opinion of Bom is wrong. give a set of values f a, b , c and d such that a>b , c>d and a+d>b+c faster plz!!!!!!

1. the sum of two consecutive is greater than 35. find the smallest values of the number let two consecutive is x,x+1 x+(x+1)>35 2x>34 x>17 x=18 so two consecutive is 18,19 2. if the sum of x, x+4, x+8 is less than 97, find the graetest value of the largest number x+(x+4)+(x+8)<97 let the largest number=y , then x+9=y (y-8)+(y-4)+(y)<97 3y<109 y<109/3 y<36.33 so the graetest value of the largest number=36 3. Bom thinks that "if a>b and c>d , then a+d>b+c" to point out that the opinion of Bom is wrong. give a set of values f a, b , c and d such that a>b , c>d and a+d>b+c if a>b and c>d but c>a & b>d then a+db , c>d] a+d=17>8+8>b+c
