The sum of 1.5x and 16.5x is equal 180°.
1.5x + 16.5x = 180
18x = 180 |:18
x = 10
The angles 20y and 16.5x are the vertical angles, therefore:
20y = 16.5x
20y = 16.5(10)
20y = 165 |:20
y = 8.25
<h3>Answer: x = 10 and y = 8.25</h3>
The median of the data set is 4. The interquartile range is UQ-LQ 5-3=2. The mean of the first set is 3.5. The mean of the second set is 5.5. Since every score went up by two, the mean went up by two as well.
I hope that helps.

Given:
The statement is "Five times the difference of the cube of y and the square of x".
To find:
The algebraic expression for the given statement.
Solution:
We know that,
Cube = Power 3
Square = Power 2
Difference = Minus (-)
Times = Multiplication (×)
Now,
Cube of y = 
Square of x = 
Difference of the cube of y and the square of x = 
Five times the difference of the cube of y and the square of x is:
Required expression = 
Therefore, the correct option is C. The required algebraic expression for the given statement is
