Una persona viaja a la ciudad X a la ciudad Y de la siguiente manera: la mitad del recorrido lo realiza en tren, la tercera part

hodyreva [135]

Tenemos que

R------------ > recorrido total
x---------------- > viaje en tren--------------- > (1/2)*R
y----------------- > viaje en bicicleta-------------(1/2)*(1/3)*R=(1/6)*R
z------------------- > viaje en automovil --------- > (1/2)*(2/3)*R=(2/6)*R=100 km
R=x+y+z
resolviendo nos queda que
(2/6)*R=100--------------- > R=100*6/2=300 km
viaje en tren----------- > (1/2)*R=300/2=150 km
viaje en bicicleta------- > (1/6)*R=300/6=50 km
( estos dos ultimos calculos no lo estan pidiendo y no hacen falta para contestar la pregunta, simplemente se realizan a manera didactica)

La respuesta es
La distancia entre las dos ciudades es de 300 km

Deepak wrote out the steps to his solution of the equation StartFraction 5 Over 2 minus 3 x minus 5 plus 4 x equals negative Sta

Anna35 [415]

Answer:

Step 1 is incorrect.

Step-by-step explanation:

The given expression is :

$\dfrac{5}{2}-3x-5+4x=\dfrac{-7}{4}$

In step 1, Deepak rearranged the terms in order to simplify like terms together that is followed in step 2.

o, rearranging of the terms of an expression is commutative property and not distributive property. The distributive property is generally applicable to multiplication and is given as:

$x(y+z)=xy+yz$
