In mathematics, the irrational numbers are all the real numbers which are not rational numbers, the latter being the numbers constructed from ratios (or fractions) of integers.
Answer:
factor
Step-by-step explanation:
We assume this is a vocabulary question and you want the word that has the definition you have supplied.
Such an expression is called a <em>factor</em>.

Answer:
![b = 9](https://tex.z-dn.net/?f=b%20%3D%209)
Step-by-step explanation:
![\frac{2}{3} b + 5 = 20 - b](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B3%7D%20b%20%2B%205%20%3D%2020%20-%20b)
In order to solve for b, we must isolate the variable. We can start by subtracting 5 from both sides.
![\frac{2}{3} b + 5 - 5 = 20 - b - 5](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B3%7D%20b%20%2B%205%20-%205%20%3D%2020%20-%20b%20-%205)
Simplify.
![\frac{2}{3} b = 15 - b](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B3%7D%20b%20%3D%2015%20-%20b)
Add b to both sides.
![\frac{2}{3} b + b = 15 - b + b](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B3%7D%20b%20%2B%20b%20%3D%2015%20-%20b%20%2B%20b)
Simplify.
![\frac{2}{3} b + b = 15](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B3%7D%20b%20%2B%20b%20%3D%2015)
Multiply everything by 3 to remove the fractions.
![3(\frac{2}{3}b+b) = 3(15)](https://tex.z-dn.net/?f=3%28%5Cfrac%7B2%7D%7B3%7Db%2Bb%29%20%3D%203%2815%29)
Simplify.
2b + 3b = 45
Simplify.
5b = 45
Divide 5 from both sides.
5b ÷ 5 = 45 ÷ 5
Simplify.
b = 9
