The prime number between 30 and 40 is 31.
To find the prime number between 30 and 40, we need to check each number in the range and determine if it is a prime number. A prime number is a positive integer greater than 1 that has no positive divisors other than 1 and itself.
Let's check the numbers between 30 and 40 one by one:
31: 31 is a prime number since it has no divisors other than 1 and 31.
32: 32 is not a prime number as it is divisible by 2 and 16.
33: 33 is not a prime number as it is divisible by 3 and 11.
34: 34 is not a prime number as it is divisible by 2 and 17.
35: 35 is not a prime number as it is divisible by 5 and 7.
36: 36 is not a prime number as it is divisible by 2, 3, 4, 6, 9, and 18.
37: 37 is a prime number since it has no divisors other than 1 and 37.
38: 38 is not a prime number as it is divisible by 2 and 19.
39: 39 is not a prime number as it is divisible by 3 and 13.
From the above analysis, we find that the prime number between 30 and 40 is 31.

Subtracting the same value from both sides of an inequality changes the solution set.
When dividing both sides of an inequality by the same positive value, it is necessary to reverse the inequality sign.
When multiplying both sides of an inequality by the same negative value, it is not necessary to reverse the inequality sign.
The statement which is true about solving inequalities is; Adding the same value to both sides of an inequality does not change the solution set.
Discussion:
Similar to equations, when solving inequalities; adding or subtracting the same value to both sides of an inequality does not change the solution set of the inequality.
In essence, the statement which is true about solving inequalities is; Adding the same value to bothsides of an inequality does not change the solution set.
