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
a + b > 30
a + b < 30
a + b < 30
b> a + 10
b b> a + 10
b< - 10

The system of inequalities which represent the value of a and b are          b + a 30   and    

b - a 10    

Step-by-step explanation:

Given as :

Statement first

The sum of two positive integers, a and b, is at least 30.

Statement second

The difference of the two integers is at least 10.

Now, According to question , b is the greater integer

So, From statement first

b + a 30

And , From statement second

b - a 10

So, from the two given statements The relation of inequalities are

b + a 30   and    b - a 10

Hence The system of inequalities which represent the value of a and b are  b + a 30   and    b - a 10       Answer

the answer is  

a.
