$$
x = 12
$$
The value of X is $\boxed{12}$.

3. "The sum of the length of any two sides of a triangle is alway the third side" The sum of the length of any two sides of a triangle is always greater than the third side.

4. "Which integer added to -7 gives?" This question is incomplete. Please specify what value it should "give".

5. "What is 3/5 of 45"

$$
135 \div 5 = 27
$$
$3/5$ of 45 is $\boxed{27}$.

6. "An exterior angle of angle is equal to" An exterior angle of a triangle is equal to the sum of the two opposite interior angles.

7. "A liner equation in one variable has a maximum power of" A linear equation in one variable has a maximum power of 1.

8. "The additive inverse of - 30 is" The additive inverse of $-30$ is $\boxed{30}$.

9. "3 / 5 divided 2 /5="

$$
\frac{15}{10} = \frac{3}{2}
$$
The result is $\boxed{\frac{3}{2}}$.

10. "The mode is the observation that occurs with the frequency in a year" The mode is the observation that occurs with the highest frequency.

11. "The product of a negative integer and a positive integer is always integer" The product of a negative integer and a positive integer is always a negative integer.

12. "X/7=4 thenx="

$$
X = 28
$$
The value of X is $\boxed{28}$.

13. "The triangle having all this side equal length is called an Triangle" The triangle having all its sides equal length is called an equilateral triangle.

14. "The Arithmetic mean of the first five natural number" The first five natural numbers are $1, 2, 3, 4, 5$.

$$
\frac{15}{5} = 3
$$
The arithmetic mean is $\boxed{3}$.

15. "In a right angle triangle the side positive to a right is called" In a right-angled triangle, the side opposite to the right angle is called the hypotenuse.
