Answer:
Se vendieron 81 boletos de niños y 63 boletos de adultos.
Step-by-step explanation:
La cantidad de boletos vendidos es igual a:
(1)
En donde <em>a </em>es por adultos y <em>n</em> por niños
A su vez, el dinero gastado equivale:
(2)
Resolviendo la ecuación (1) para <em>a:</em>
(3)
Introduciendo (3) en la ecuación (2) tenemos:
Ahora podemos calcular el numero de boletos de adultos vendidos introduciendo <em>n</em> en la ecuación (3):
Entonces, se vendieron 81 boletos de niños y 63 boletos de adultos.

Answer: The answer should be B
When two lines cross, there are four angles at the place where they cross.
Two angles that do NOT share a side are vertical angles. There are two pairs
of vertical angles where the lines cross.
Also, by the way, vertical angles are always equal to each other. It's often
very helpful to know that.
Angle 3 and angle 4 are supplementary angles and when added together need to equal 180 degrees.
To find angle 4 subtract angle 3 from 180.
Angle 4 = 180 - 101 = 79 degrees.
Answer: QN = 12
Step-by-step explanation: This quadrilateral is a paralelogram because its 2 opposite sides (NP and MQ) are parallel and the other 2 (MN and PQ) are congruent.
In paralelogram, diagonals bisect each other, which means QR = RN.
If QR = RN:
QR = 6
Then,
QN = QR + RN
QN = 6 + 6
QN = 12
<u>The diagonal QN of quadrilateral MNPQ is </u><u>QN = 12</u><u>.</u>
