Answer:
y = 175. x = 300. Disney vacation is 300 sold. Cars sold were 175.
Step-by-step explanation:
They want to raise $80,000. There are a total of 475 tickets.
150x + 200y (Disney Vacation + Win a car) = 80,000
x + y = 475.
__
y=475-x
150x+200(475-x)=80000
150x+95,000-200x=80,000.
-50x + 95,000 = 80,000.
-50x = -15,000
x = 300.
Disney vacation is 300 sold.
300 + y = 475.
y = 175.
Cars sold were 175.

I am 14 years old and I'm learning solving the systems by elimination and substitution, etc. Hope this is the correct answer.
Answer:
The correct option is (D).
Step-by-step explanation:
A quadrilateral is a parallelogram if the following conditions are met:
- If two pairs of opposites are equal in length.
- If two opposite sides are parallel to each other and are equal.
- If the diagonals bisect each other in equal halves.
So, for a parallelogram the opposite sides are equivalent in length.
From the provided length of 4 sides of a quadrilateral, consider the sides provided by option D.
4, 9, 9, 4
Two sides are of length 4 units and two of 9 units.
According to condition 1, the sides {4, 9, 9, 4} can form a parallelogram.
Thus, the correct option is (D).

Answer:
x=5
Step-by-step explanation:
I first subtracted 88 from 180 because we know that 180 is the total degree of the three angles in a trangle. I got 92, then divided that by 2 since there are two angles that are unknown. I got 46, which I can then use to form the equation (9x+1)=46. I subtracted 1 from both sides to get rid of the 1 (since we're finding what x equals to), I then got 9x=45. After that, I divided 9 from both sides and got the answer x=5.
Hope this helped you : )
