Un fabricante de ventanas cuadradas cobra a razón de 3 euros por cada metro de marco y 12 euros por el cristal, sean cuales sean
lesya [120]

Answer:

Givens

  • The cost of the square windows is 3 euros per meter, and 12 euros for the crystal.

<h3>If a window has 2 meters side, how much would it cost? (A)</h3>

Notice that the window is a square, that means all four sides are congruent, so it has 8 meters in total, which would cost 24 euros plus the crystal. Therefore, the total cost of a window with 2 meters side is 24+12 = 36 euros.

Specifically, the function of the cost is: C(x)=3x+12, where x represents meters of sides. (C)

<h3>If we paid 60 euros, the dimensions are (B)</h3>

60=3x+12\\60-12=3x\\x=\frac{48}{3}=16

The window has 16 meters between the four sides, which gives 5 meters per side.

The graph of the function is attached.

The fair will be traveling to a place that uses the metric system. They received directions to their next stop, but they are in
MariettaO [177]

Answer:

2x - 0.4x ;

8x/5 ;

Yes

Step-by-step explanation:

Let number of miles = x

Arlene:

Double number of miles = 2 * x = 2x

Subtract 20% of the result :

2x - 20% of 2x ;

2x - 0.4x

Raul:

Divides Number of miles by 5 ; x / 5

Multiplies result by 8 ;

8 * (x/5) = 8x /5

To know if expressions are equivalent :

Let x = 10 miles

Using Arlene's expression:

2x - 0.4x

x = 10

2(10) - 0.4(10) = 16

Using Raul's expression :

8x / 5

(8*10) / 5

80/5

= 16

Since they give the same result, we can conclude that the expression are equivalent
