C. 27x-67
Step-by-step explanation:
To simplify, combine like terms meaning variable terms with variable terms and constants with constants.
81x-54x = 27x
-46-21=-46+-21=-67
The expression is 27x-67
All natural numbers are whole numbers.
All whole numbers are integers.
All integers are rational numbers.
Thus one point can be used to represent the natural numbers, the whole numbers, the integers and the rational numbers while another point represent the irrational numbers.
The real numbers are made up of the rational and the irrational numbers.
Therefore, <span>the
fewest number of distinct points that must be graphed on a number line,
in order to represent natural numbers, whole numbers, integers,
rational numbers, irrational numbers, and real numbers is 2 points.</span>
