Answer:
No solutions
Step-by-step explanation:
Solve for x the system of two inequalities:
First, solve each inequality separately:
1.
2.
Now, we get
and
There are no common values for x, for which both inequalities hold, so the system of two inequalities has no solutions.
Answer:
Step-by-step explanation:
Given
The sum of the two positive integer a and b is at least 30, this means the sum of the two positive integer is 30 or greater than 30, so we write the inequalities as below.
The difference of the two integers is at least 10, if b is the greater integer then we subtract integer a from integer b, so we write the inequality as below.
Therefore, the following system of inequalities could represent the values of two positive integers a and b.
