La frase lingüística "cuatro veces un número dividido por la suma de dos
polet [3.4K]

Answer:

Las opciones no se pueden ver, así que responderé de una forma general.

Primero rompamos la frase en partes más cortas

"cuatro veces un número..."

Esto se escribe como 4*N, donde N es el número.

"... la suma de dos

números"

Esto se escribe como K + M

donde K y M son dos números, entonces K + M es la suma de dos números.

Entonces:

"cuatro veces un número dividido por la suma de dos

números"

Se escribirá como:

(4*N)/(K + M )

Does anyone know this ?
Alina [70]

Answer:

Equation: 12 + 3x = 30

Solution: x = 6

Step-by-step explanation:

12 + 3x = 30

X stands for how many hours she rented it for. You want to solve for x, so get x by itself.

12 + 3x = 30

-12           -12

---------------------

3x = 18

Divide both sides by 3

3/3x = 18/3

x = 6
