Answer:

1)

82.5 - <u>8</u><u>2</u><u>.</u><u>5</u> + 2x = 338.5 - <u>8</u><u>2</u><u>.</u><u>5</u>

<u>2</u>x = <u>2</u><u>5</u><u>6</u>

2)

2x ÷ <u>2</u> = 256 ÷ <u>2</u>

x = <u>1</u><u>2</u><u>8</u>

Step-by-step explanation:

1)

In order to get rid 82.5, you have to substract the same value on both side to get a 0 value.

2)

In order to find the value of x, you have to divide the value that is sticked with x which is 2. As you divide 2 by 2, you will get 1 as a single value of x so you have to divide 2 to both side too.

Si 15 obreros construyen un muro en 45 minutos, ¿en cuánto tiempo lo construirán 3 obreros con similar habilidad?
Alexxx [7]

Answer:

3 obreros tardaran 225 minutos en completar el trabajo.

Step-by-step explanation:

Sea R la velocidad con la que un obrero puede construir 1 muro.

Sabemos que 15 obreros construyen un muro en 45 minutos, entonces:

(15*R)*45min = 1 muro

Con esta ecuación podemos encontrar el valor R

R = (1 muro)/(15*45min)  

Ahora queremos saber cuando tiempo tardan 3 obreros en construir un muro, entonces tenemos que resolver:

(3*R)*T = 1 muro

Reemplazando el valor de R obtenemos:

(3*(1 muro)/(15*45min))*T = 1 muro

T = (1 muro)*(15*45 min)/(3*1 muro)

T = 5*45min = 225 min

3 obreros tardaran 225 minutos en completar el trabajo.
