Answer:

El precio de la falda es 50 €.

Step-by-step explanation:

Lo que sabemos:

F = 5 + B   (1)

En donde F es por falda y B por blusa.

Si compras 6 faldas y 4 blusas y pagas 480 €:

6F + 4B = 480  (2)

Entonces, al introducir la ecuación (1) en (2) podemos hallar el precio de cada falda.

6F + 4B = 480

6(5 + B) + 4B = 480

10B = 480 - 30

B = \frac{450}{10} = 45  

Finalmente, el precio de la falda se puede encontar con la ecuación (1):

F = 5 + 45 = 50

Por lo tanto, el precio de la falda es 50 €.  

Espero que te sea de utilidad!

Reflect square JKLM with J(1, 4), K(6, 5), L(7, 0) and M(2, -1) in the y-axis. What are the coordinates of M'?
ANTONII [103]

Given:

Reflect square JKLM with J(1, 4), K(6, 5), L(7, 0) and M(2, -1) in the y-axis.

To find:

The coordinates of M'.

Solution:

We have, M(2, -1) .

If a  figure reflected over the y-axis then

(x,y)\to (-x,y)

Using this rule, we get

M(2,-1)\to M'(-2,-1)

Therefore, the coordinates of point M' are (-2,-1).

3x - 5y = 10 Solve For y
kaheart [24]

Answer:

<h2>y =  \frac{3x - 10}{5}</h2>

Step-by-step explanation:

3x - 5y = 10

Move 5y to the right side of the equation

That's

10 + 5y = 3x

Move 10 to the right side of the equation

We have

5y = 3x - 10

Divide both sides by 5 to make y stand alone

That's

<h3>\frac{5y}{5}  =  \frac{3x - 10}{5}</h3>

We have the final answer as

<h3>y  = \frac{3x - 10}{5}</h3>

Hope this helps you
