Por medio de sistema de ecuaciones:
*adultos (a) = $400
*niños (b) = $150
total de entradas : a + b = 600 ecua 1
dinero recaudado:
400a + 150b = 196 250 ecua 2
operamos:
a + b = 600 ecua 1
400a + 150b = 196 250 ecua 2
--------------------------
(-150) a + b = 600
400a + 150b = 196 250
-----------------------
- 150a - 150b = -90 000
400a + 150b = 196 250
-----------------------
250a = 106 250
a = 106 250/250
a = 425 adultos
a + b = 600
425+b =600
b = 600-425
b = 175 niños
comprobacion:
400a + 150b = 196 250
400(425)+150(175)=196 250
170 000 + 26 250 = 196 250
196 250 = 196 250

Answer:
, the fourth option.
Step-by-step explanation:
Tan means 
or opposite side divided by adjacent side.
Tan A equals the opposite side of the angle A divided by its adjacent side.
The side opposite of A is y and side adjacent to it is x.
So, Tan A equals !
First Method (Distributive Property)
(2m - 5m) (-5)
Rearrange the equation to make it easier.
(-5) (2m - 5m)
In distributive property, it's all about multiplying. The -5 goes to the 2m and the 5m. Like this: (-5 • 2m) - (-5 • 5m).
-10m + 25m
15m
Second Method
(2m - 5m) (-5)
Since 2m and 5m have the same variable, we can subtract them.
(-3m) (-5)
Multiply.
15m
15m is your answer. I hope this helps!
