Question

The sum of two positive integers, a and b, is at least 30. the difference of the two integers is at least 10. if b is the greater integer, which system of inequalities could represent the values of a and b? a b ≥ 30 b ≥ a 10 a b ≥ 30 b ≤ a – 10 a b ≤ 30 b ≥ a 10 a b ≤ 30 b ≤ a – 10

Answer 1

a + b > = 30 (greater then or equal)
b - a > = 10 (greater then or equal).......b > = a + 10

Answer 2

a + b ≤ 30 b ≥ a + 10
