adult ticket = 10
child ticket = 4
Step-by-step explanation:
for example…
- adult ticket = x
- child ticket = y
so that we get a system of equations
9x + 5y = 110…Equation 1
x + y = 14…Equation 2
solve the system of equations, this time I will use the Elimination and Substitution method
9x + 5y = 110
x + y = 14 (multiplied by 5)
↓↓↓↓↓↓↓
9x + 5y = 110
5x + 5y = 70
___________ _
4x = 40
<u>x = 10</u>
to find value of y subtitute x to one of Equation. for example from second Equation…
x + y = 14
10 + y = 14
y = 14 - 10
<u>y = 4</u>
∴ So, the number of each ticket was she bought is <u>10 adult ticket</u> and <u>4 child </u><u>ticket.</u>
Answer:
C) Subtraction property of equality.

Given that, two lines 
and 
intersect to make pairs of vertical angles:
and 
.
Kindly refer to the attached image for details of the given angles and lines.
Proof that 
:
Here, subtraction property of equality is used in the last step shown in the above.
As per the <em>Subtraction property </em>of equality, when some value is subtracted from both the sides of the equality, equality remains the same.
