Answer:
You sold 20 student tickets.
Step-by-step explanation:
Given that:
Total tickets sold = 27
Total amount collected = $170
Cost of student ticket = $5
Cost of adult ticket = $10
Let,
x be the number of students tickets sold
y be the number of adult tickets sold
x+y = 27 Eqn 1
5x+10y=170 Eqn 2
Multiplying Eqn 1 by 10
10(x+y=27)
10x+10y=270 Eqn 3
Subtracting Eqn 2 from Eqn 3
(10x+10y)-(5x+10y)=270-170
10x+10y-5x-10y=100
5x=100
Dividing both sides by 5
Hence,
You sold 20 student tickets.
The true statement about the quadrilateral is ABCD is a rhombus with non-perpendicular adjacent sides.
<h3>How to determine the true statement?</h3>The coordinates are given as:
A(4, 5), B(2, 4), Q4, 3), and D(6, 4).
Next, we plot the graph of the quadrilateral ABCD
See attachment
From the attached graph, we have the following highlights:
- Opposite sides are equal
- Opposite sides are parallel
- Adjacent sides are not perpendicular
This means that the quadrilateral is ABCD is a rhombus
