Answer:
it's C. BD is equal to DB .
Step-by-step explanation:
the last pair of side, which can be proved equal are BD and DB because the sides are common in both the triangles, making the triangles congruent by SSS Postulate...
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>
