Answer:

x = -2 y = -4

Step-by-step explanation:

3x- 2y = 2 -> 15x - 10y = 10

5x - 5y = 10 -> 15x - 15y = 30

Substract one equation from another:

15x - 15x - 10y + 15y = 10 -30

5y = -20

y = -4

Plug in y into an equation

3x + 8 = 2

3x = - 6

x = - 2

3-4 litros de jugo de frutilla 1 y 1-2 litros de jugo de manzana 1-8 litro de jugo consentrado de limón . 1 y 1-2 litro de agua.
Neko [114]

Answer:

Hay 3,875 litros de jugo multifrutal.  

Step-by-step explanation:

<em>(Se asume que el problema fue propuesto en un país distinto a los Estados Unidos, razón por la cual se emplea las reglas del Sistema Internacional.)</em>

La capacidad de jugo multifrutal en el bidón se obtiene con la mezcla de cada jugo frutal y se logra mediante la suma de cada capacidad. A partir del enunciado, tenemos que la capacidad del jugo multifrutal es:

V = \frac{3}{4}\,L + 1\,\frac{1}{2}\,L + \frac{1}{8}\,L + 1\,\frac{1}{2}\,L

V = \frac{3}{4}\,L + 1\,L + \frac{1}{2}\,L + \frac{1}{8}\,L + 1\,L + \frac{1}{2}\,L

V = 3,875\,L

Hay 3,875 litros de jugo multifrutal.

Genevieve wants to verify that One-fifth (5 x minus 20) minus one-half (4 x minus 8) is equivalent to Negative x. Which procedur
lora16 [44]

Answer:

The given expression is equivalent to -x

That is \frac{1}{5}(5x-20)-\frac{1}{2}(4x-8)=-x

Now Verified that the two expressions are equivalent

Step-by-step explanation:

Given that Genevieve wants to verify that One-fifth (5 x minus 20) minus one-half (4 x minus 8) is equivalent to Negative x

It can be written as below :

\frac{1}{5}(5x-20)-\frac{1}{2}(4x-8)=-x

Now we can verify the expression is equivalent or not :

Taking  LHS

\frac{1}{5}(5x-20)-\frac{1}{2}(4x-8)

=\frac{5x}{5}+\frac{-20}{5}-\frac{4x}{2}+\frac{8}{2} ( by using the distributive property )

=x-4-2x+4

=-x+0  ( adding the like terms )

=-x=RHS

Therefore LHS=RHS

Therefore the given expression is equivalent to -x

That is \frac{1}{5}(5x-20)-\frac{1}{2}(4x-8)=-x

Now Verified that the two expressions are equivalent
