Answer:
612 students and 325 adults.
Step-by-step explanation:
To determine the number of adults and students who attended the event, knowing that in total there were 937 people who spent a total of $ 1,109 and that each student ticket is worth $ 0.75 while each adult ticket is worth $ 2, the following logical reasoning must be performed:
2 - 0.75 = 1.25
Therefore, the minimum that each ticket will be worth is $ 0.75, while there will be a surplus of money that will be divisible by 1.25, which is the amount of more that each adult paid on their ticket.
Therefore, since 0.75 x 937 equals 702.75, the total price surplus is 406.25 (1,109 - 702.75). Now, this number divided by 1.25 gives a total of 325, with which 325 adults attended the event. In turn, given that the total number of attendees was 937, the total number of students who attended the event is 612 (937 - 325).
The value of the variables are y = -45/2, r = -9, x = 2/9 and x = 2
<h3>How to solve the variables?</h3>
<u>(1) y/3 + 6 = -3/2</u>
Multiply through by 3
y + 18 = -9/2
Subtract 18 from both sides
y = -18 - 9/2
Take LCM
y = (-18 * 2 - 9)/2
Evaluate
y = -45/2
<u>(2) -2r/3 - 3 = 3</u>
Multiply through by 3
-2r - 9 = 9
Add 9 to both sides
-2r = 18
Divide by 2
r = -9
<u>(3) 2/3 - 2x = x</u>
Multiply through by 3
2 - 6x = 3x
Add 6x to both sides
2 = 9x
Divide by 9
x = 2/9
<u>(4) 7x/2 + -5/2 = 9/2</u>
Multiply through by 2
7x - 5 = 9
Add 5 to both sides
7x = 14
Divide by 7
x = 2
Hence, the value of the variables are y = -45/2, r = -9, x = 2/9 and x = 2

Answer:
1. We can't see the full question, she could have drawn any of them.
2. C Because a square is a rectangle and a rhombus is a square meaning a rhombus CAN be a rectangle.
3. Whole : 6
Tenth : 5.7
Hundredth : 5.68

Each loop is of a different size, so we can't rotate the figure some angle x to have it line up with itself (0 < x < 360). Therefore, it doesn't have any rotational symmetry. That rules out choice A and choice C. Point symmetry is the same as saying "rotational symmetry of 180 degrees"
The figure doesn't have any line symmetry either. There is no line we can draw and reflect the figure over to have it match up with itself. That rules out choice B and points to choice D
Answer: D) It has no reflectional symmetry.
