What is the solution to the following system?

hodyreva [135]

Answer:

The correct answer is option 3. (20, 4, 5)

Step-by-step explanation:

To solve this problem we use the substitution method.

$3x + 10y -12z = 40$ (i)

$x-5y = 0$ (ii)

$x - 4z = 0$ (iii)

We start by clearing x in (iii) and clearing y in (ii).

$x = 4z$ (iii)

$y = \frac{1}{5}x$ (ii)

Now we substitute (iii) in (ii)

$y = \frac{4}{5}z$ (iv)

Now we substitute (iii) and (iv) into (i) and clear z.

$12z + \frac{40}{5}z -12z = 40$ (v)

$8z = 40$

$z = \frac{40}{8}$

$z = 5$

If $z = 5$ (v)

We substitute (v) in (iii) and then substitute (v) in (iv)

$x = 20\\y = 4\\z = 5$

The correct answer is option 3.

Answer:

La familia ha bebido en un día de verano $5\,\frac{1}{4}$ litros.

Step-by-step explanation:

Podemos evidenciar que es posible obtener el volumen total de los citados líquidos al sumar el volumen de cada uno. El volumen de cada bebida es igual al producto de su capacidad multiplicada por el número de botellas. Es decir:

$V_{total} = V_{agua} + V_{jugo} + V_{limonada}$

Donde todos los volúmenes se miden en litros.

$V_{total} = (2\,botellas)\times \left(\frac{3}{2} \,\frac{L}{botella} \right)+(5\,botellas)\times \left(\frac{1}{4}\,\frac{L}{botella} \right) + (4\,botellas)\times \left(\frac{1}{4}\,\frac{L}{botella} \right)$

$V_{total} = (2\,botellas)\times \left(\frac{6}{4} \,\frac{L}{botella} \right)+(5\,botellas)\times \left(\frac{1}{4}\,\frac{L}{botella} \right) + (4\,botellas)\times \left(\frac{1}{4}\,\frac{L}{botella} \right)$

$V_{total} = \frac{12}{4}\,L + \frac{5}{4} \,L + \frac{4}{4} \,L$

$V_{total} = \frac{21}{4}\,L$

$V_{total} = \frac{20}{4}\,L + \frac{1}{4}\,L$

$V_{total} = 5\,\frac{1}{4}\,L$

La familia ha bebido en un día de verano $5\,\frac{1}{4}$ litros.
