The statement that's true about the triangle is that WXY + YXZ = 180°.
<h3>How to illustrate the information?</h3>
It should be noted that in the question, the options are related to a linear pair.
According to the linear pair, when a line cuts another line at a point, then the sum of the adjacent angles formed at the point will be 180°.
Therefore, WXY + YXZ = 180°.
The correct option is C.
The complete question is:
Which statement regarding the diagram is true?
m∠WXY = m∠YXZ
m∠WXY < m∠YZX
m∠WXY + m∠YXZ = 180°
m∠WXY + m∠XYZ = 180°

Answer:
$11,250
Step-by-step explanation:
Normally, when I work "mixture" problems, I like to choose the variable so it represents the amount of the largest contributor. Here, that would be the amount invested at 15%.
Unfortunately, the question asks for the amount invested at 7%. Using a variable to represent that amount means that there will be negative numbers involved. Care must be taken in the arithmetic.
Let x represent the amount invested at 7%. Then 16000-x is the amount invested at 15%. The total interest for one year is ...
0.07x + 0.15(16000 -x) = 1500 . . . . sum of interest amounts at each rate
-0.08x +2400 = 1500 . . simplify
-0.08x = -900 . . . . . . . . subtract 2400
x = 11250 . . . . . . . . . . . . divide by -0.08
The bank loaned $11,250 at 7%.
Let the number of adult be x and the number of children be y.
There is a total of 11 people
x + y = 11
Total cost of tickets is $228
22x + 15y = 228
x + y = 11 ----------------- (1)
22x + 15y = 228 ---------(2)
From (1):
x+ y = 11
x = 11 - y --- sub into (2)
22 (11 - y) + 15y = 228
242 - 22y + 15y = 228
-7y = 228 - 242
-7y = -14
y = 2 ---- sub into (1)
x+ 2 = 11
x = 9
Number of adult tickets = 9
Number of child tickets = 2
5•6=30
30-5/5=29
(5/5=1)
29+2=31
