Answer: k = -2
solution: 2kx-3k<2x+4+3kx,

Un terreno ha sido cultivado con tres variedades de claveles. La sexta parte ha sido sembrada por
Minchanka [31]

Answer:

1) Se siembra cinco doceavas partes del terreno con claveles rojos y amarillos, 2) Se siembra siete doceavas partes del terreno con claveles blancos.

Step-by-step explanation:

El enunciado se encuentra incompleto. La pregunta faltante es:

2 ¿Qué parte del terreno corresponde a los claveles blancos?

1) Sea A el área total sembrada con los tres tipos de claveles. Entonces, las áreas sembradas con claveles rojos y claveles amarillos son \frac{1}{6}\cdot A y \frac{1}{4} \cdot A, respectivamente.

El área sembrada con claveles rojos y amarillos se obtiene al sumar las áreas correspondientes, es decir:

x = \frac{1}{6}\cdot A + \frac{1}{4}\cdot A

x = \left(\frac{1}{6}+\frac{1}{4}\right)\cdot A

x = \left(\frac{4+6}{24} \right)\cdot A

x = \frac{10}{24}\cdot A

x = \frac{5}{12}\cdot A

Se siembra cinco doceavas partes del terreno con claveles rojos y amarillos.

2) El área sembrada con claveles blancos se obtiene al sustraer el área obtenida en el punto anterior del área total. Esto es:

x = A - \frac{5}{12}\cdot A

x = \left(1-\frac{5}{12} \right)\cdot A

x = \left(\frac{12}{12}-\frac{5}{12}  \right)\cdot A

x = \left(\frac{12-5}{12} \right)\cdot A

x = \frac{7}{12}\cdot A

Se siembra siete doceavas partes del terreno con claveles blancos.
