Answer:

El numero es 2

Step-by-step explanation:

Sea x el número.

A partir de la pregunta, la expresión se puede representar matemáticamente como:

3x ^ 2 = 6x

Divide ambos lados de la expresión por x

\frac{3x ^ 2}{ x} = \frac{6x }{ x}

\frac{3x ^ 2}{ x} = 6

3x = 6

Divide ambos lados de la expresión por 3

\frac{3x}{3} = \frac{6}{3}

x = \frac{6}{3}

x = 2

Por tanto, el número es 2

Annette [7]

Answer:

<h3>100</h3>

Step-by-step explanation:

Let the number we are looking for be x. If Jack divided 1,826.5 by the number to get a quotient of 18.265, to get the number we will solve the equation;

1,826.5/x = 18.265

Cross multiply

1826.5 = 18.265x

Divide both sides by 18.265

18.265x = 1826.5

18.265x/18.625 = 1826.5/18.625

x =  100

Hence Jack divide 1,826.5 by 100 to get a quotient of 18.265
