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

Step-by-step explanation:

Given

Two integers a and b

The first statement in the question says, their sum is at least 30

The keyword "at least" means their sum can not fall below 30 and this is represented mathematically as

The next statement says their difference is at least 10 and b is greater;

The keyword "at least" means the same as used above (i.e. can not exceed); The second statement is represented as:

Hence, the system of inequality that represents the statements are:

all of the other ones have a specific pattern
