Todos los días por la mañana Alfonso maneja a una velocidad de 80 km/hr para llegar a su trabajo a tiempo realizando un tiempo de 42min de regreso por la tarde disminuye su velocidad a 65km/hr ¿cuanto tiempo tarda para llegar a casa

Answers

Answer 1
Estoy usando el traductor de en línea. No hablo mucho español.

Distancia = velocidad x tiempo
= 80 km/hr x 42 minutos
= 56 km


Tiempo = distancia / velocidad
= 56 km / 65 km/hr
= 51,6923 minutos
= 51,6923 min
= 0 horas, 51 minutos, 42 segundos

Espero que esto te ayude.

Answer 2

Usando proporciones, tiene-se que tardará 52 minutos para llegar a casa.

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

Esta pregunta se resuelve por proporciones, usando una regla de tres. Considerando que la velocidad y el tiempo son inversamente proporcionales, a medida que uno aumenta y el otro disminuye, se aplica una regla inversa de tres, en la que la multiplicación está en la línea en lugar de cruzada.

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

80km/hr tiene un tiempo de 42 min. Qual el tiempo a una velocidad de 65 km/hr?

80 km/hr - 42 min

65 km/hr - x min

Multiplicando las líneas:

[tex]65x = 80 \times 42[/tex]

[tex]x = \frac{80 \times 42}{65}[/tex]

[tex]x = 52[/tex]

Tardará 52 minutos para llegar a casa.

What is 3х – 18y = 4

Answers

The answer is no solution

Simplifying
3x + -18y = 4

Solving
3x + -18y = 4

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '18y' to each side of the equation.
3x + -18y + 18y = 4 + 18y

Combine like terms: -18y + 18y = 0
3x + 0 = 4 + 18y
3x = 4 + 18y

Divide each side by '3'.
x = 1.333333333 + 6y

Simplifying
x = 1.333333333 + 6y

8. Flour = 150 grams

9. Original sum of money = 110 pounds

Step-by-step explanation:

8. Let the quantities of butter, flour and sugar be 2x, 3x and 4x grams respectively.

So,

2x + 3x + 4x = 450

9x = 450

x = 450/9

x = 50

Flour = 3x = 3*50 = 150 gram

9.

Let Abby, Neil and Dylan have 2x, 4x and 5x pounds respectively.

Since Neil has 40 pounds.

So, 4x = 40

x = 40/4

x = 10

Total amount = 2x + 4x + 5x = 11x = 11*10 = 110 pounds.

Original sum of money = 110 pounds
