30 - 18 = 12....so they make a 0.12 cent profit off each CD

0.12x > 6000
x  > 6000/0.12
x > 50,000....so basically, they have to make 50,001 CD's

en una balansa de platillos esta equilibrada, en uno de los platillos hay una piedra, una pesa de un noveno kilogramos y la otra
Komok [63]

Se escribe una equacion y se resolve.

Vamos a usar x para representar el peso de la piedra.

En en platillo que tiene la piedra, el peso total es: x + 1/9 + 2/3

En el otro platillo: 1/2 + 1/3

La balanza esta equilibrada por eso los pesos en los platillos son iguales.

x + 1/9 + 2/3 = 1/2 + 1/3

x + 2/18 + 12/18 = 9/18 + 6/18

x + 14/18 = 15/18

x = 1/18

Respuesta: La piedra pesa un octavo de kilogramo.

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

5(x + 2) = 6x + 3x - 14

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. [Addition] Combine like terms:                                                                        5(x + 2) = 9x - 14
  2. [Distributive Property] Distribute 5:                                                                 5x + 10 = 9x - 14
  3. [Subtraction Property of Equality] Subtract 9x on both sides:                      -4x + 10 = -14
  4. [Subtraction Property of Equality] Subtract 10 on both sides:                       -4x = -24
  5. [Division Property of Equality] Divide -4 on both sides:                                x = 6
