Answer:
Vertical angles = 81 degrees
Angle (4y-1) = 99 degrees
Linear pair = 81 + 99 = 180 degrees
Step-by-step explanation:
2x + 5 = 3x - 33 (vertical angles)
33+5 = 3x - 2x
38 = x
3(38) - 33 = 81 degrees
4y - 1 + 81 = 180 (linear pair angles)
4y = 180 - 80
y = 100/4
y = 25
4(25) -1 = 99 degrees
18 & 18. I like it.
The square root of a natural number won't be rational unless the number is a perfect square. So not a and not b but yes to C.
For d, -0.125374..., we can't really tell. The three dots tells us it goes on. There's no indication of a repeat but we can't assume it doesn't repeat either. For d the correct answer is cannot be determined.
OK, onto 18.
The square root of 12 is irrational so has a nonterminating, nonrepeating decimal expansion.
7/8 has a finite decimal expansion, 0.875. When the reduced denominator doesn't have any prime factors besides 2 and 5 we'll get a finite decimal expansion. Answer: b
5/11 has 11 as a factor in the denominator, so is an infinite repeating decimal.
I'll guess there's three dots after 0.81818181 so that one doesn't terminate either.

Bonus
0.21 rational, equal to 21/100
3/12 rational, it's the ratio of integers
√12 - 2 is irrational because of the √12
4.125... can't really tell because the ... may hide a repeating or nonrepeating part.
