The word "triple" begins with the prefix "tri," which means "three." So to triple something you would need to multiply by three. You can also get the same answer by simply adding the number three times. For example, to triple 5 you could either multiply 5 by 3 or add 5+5+5 to get 15.
you call it algebra because it has an unknown number which you have to solve for
This depends on what Algebra Book you are referring to.
Pie is a symbol that represents a number (3.14159...). Pie algebra is when the number Pie is used in algebra like the ccircumference of a circle. A circumference of a circle is worked out by Pie algebra: DxPie (diameter x Pie). Its a bit complicated to explain but...
The coefficient in algebra is the number before a letter with an exponent on it. The 3 is the coefficient in this example: 3x7
A number consisting of 2 integers
To obtain the triple corresponding number in algebra format, you would have to multiply it by 3 and square it. This is a very quick method of obtaining the answer. If it was a prime number, then you would have to multiply it by 3 and double the answer. You don't have to subtract the answer from the corresponding number because it just makes things complicated. This is the easiest method available.
You use it to find how long it takes to double or triple the amount you put in with rate and time. It's in Algebra 2.

In geometry, supplementary angles add to 180 degrees. The term 'supplementary number' is not used in algebra.

The point of using letters in algebra is that they can stand for any number (or a range of numbers that are, as yet, unspecified). There is no specific letter allocated to a number.
