Two-fifths of one less than a number is less than three-fifths of one more than that number. What numbers are in the solution se
t of this problem?
x<-5
x>-5
x<-1
x>-1
2 answers:
2/5 * (n - 1) < 3/5 * (n + 1)
2/5 * n - 2/5 < 3/5 * n + 3/5
- 2/5 - 3/5 < 3/5 * n - 2/5 * n
- 5/5 < 1/5 * n
- 1 < 1/5 * n /*5
- 5 < n
n > - 5
n = x
The correct result would be B) <span>x > - 5.</span>
Answer: The correct option is (B) x > -5.
Step-by-step explanation: Given that two-fifths of one less than a number is less than three-fifths of one more than that number.
We are to find the numbers that are in the solution set of this problem.
Let, 'x' represents a number in the solution set.
Then, according to the given information, we have

Thus, the solution set is represented by the number 'x' such that
x > -5.
Option (B) is correct.
