ANSWER
The correct answer is D.
EXPLANATION
If we express the monomial,
![18 {x}^{2} y](https://tex.z-dn.net/?f=18%20%7Bx%7D%5E%7B2%7D%20y)
as product of primes, we obtain:
![2 \times {3}^{2} \times {x}^{2}y](https://tex.z-dn.net/?f=2%20%5Ctimes%20%20%7B3%7D%5E%7B2%7D%20%20%5Ctimes%20%20%7Bx%7D%5E%7B2%7Dy%20)
If we express the monomial
![27x {y}^{3}](https://tex.z-dn.net/?f=27x%20%7By%7D%5E%7B3%7D%20)
as product of primes we obtain:
![= {3}^{3} \times x {y}^{3}](https://tex.z-dn.net/?f=%20%3D%20%20%7B3%7D%5E%7B3%7D%20%20%5Ctimes%20x%20%7By%7D%5E%7B3%7D%20)
The least common multiple of these two binomials is the product of the highest powers of the common factors.
The LCM is
![= 2 \times {3}^{3} \times {x}^{2} {y}^{3}](https://tex.z-dn.net/?f=%20%3D%202%20%5Ctimes%20%20%7B3%7D%5E%7B3%7D%20%20%5Ctimes%20%20%7Bx%7D%5E%7B2%7D%20%7By%7D%5E%7B3%7D%20%20)
![=54 {x}^{2} {y}^{3}](https://tex.z-dn.net/?f=%20%3D54%20%7Bx%7D%5E%7B2%7D%20%7By%7D%5E%7B3%7D%20%20)
Therefore the correct answer is D.

Answer:
b)
Step-by-step explanation:
Answer:
The number of children's tickets sold was 27
Step-by-step explanation:
Let
x ----> the number of children's tickets sold
y ----> the number of adult's tickets sold
we know that
----> equation A
----> equation B
Solve the system by substitution
Substitute equation B in equation A
![6.10x+9.40(4x)=1,179.90](https://tex.z-dn.net/?f=6.10x%2B9.40%284x%29%3D1%2C179.90)
solve for x
![6.10x+37.6x=1,179.90](https://tex.z-dn.net/?f=6.10x%2B37.6x%3D1%2C179.90)
![43.7x=1,179.90](https://tex.z-dn.net/?f=43.7x%3D1%2C179.90)
![x=27](https://tex.z-dn.net/?f=x%3D27)
therefore
The number of children's tickets sold was 27
