Answer:
x = 30
Step-by-step explanation:
Since you're dividing x by 3, multiply each side by 3. The 3 on the left side gets cancelled out, leaving you with x = 30.

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:
a
Step-by-step explanation:
The sequence jumps by intervals of 3 each time. This tells us that the answer has 3n in it. Then, we know that the first value is two, which is 1 less than 3. This means the answer is a, 3n-1.
Answer:
5
Step-by-step explanation:
The complex number 4 + 2i on the complex plane has coordinates (4,2) and the complex number 7 - 2i has coordinates (7,-2). Thus, the length of a segment in the complex plane with endpoints at 4 + 2i and 7 – 2i is
