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

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

step-by-step explanation:

the answer is 128
