Answer:
C. Non-repeating and non-terminating.
Step-by-step explanation:
We know that, rational numbers are of the form 
, where q≠0 and p,q are integers.
If we take q=1, then the rational number is 
= p, where p is an integer.
So, option B represents a rational number.
Let us consider, 
= 0.31645569620253.
So, we can see that a rational number can be written in the form of repeating and terminating decimals.
So, option A and D also represents a rational number.
Therefore, option C i.e. non-repeating and non-terminating does not represents a rational number as it represents an irrational number.
Hence, option C is correct.
Answer:
Simplifying
3x + 77 = 4x + 54
Reorder the terms:
77 + 3x = 4x + 54
Reorder the terms:
77 + 3x = 54 + 4x
Solving
77 + 3x = 54 + 4x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-4x' to each side of the equation.
77 + 3x + -4x = 54 + 4x + -4x
Combine like terms: 3x + -4x = -1x
77 + -1x = 54 + 4x + -4x
Combine like terms: 4x + -4x = 0
77 + -1x = 54 + 0
77 + -1x = 54
Add '-77' to each side of the equation.
77 + -77 + -1x = 54 + -77
Combine like terms: 77 + -77 = 0
0 + -1x = 54 + -77
-1x = 54 + -77
Combine like terms: 54 + -77 = -23
-1x = -23
Divide each side by '-1'.
x = 23
Simplifying
x = 23
