Answer:

B. <em>x + y = 180°</em> and C.<em> y = z</em>

x = 180° - 82° - 54°

x = 64°

x + y = 180°

64° + 136° = 180°

so, x + y = 180° it's should be correct

∠y°,∠z° are vertical opposite angles.

In a class 5/8 of pupils are boys.If 15 girls are in that class how many boys are there​
Kobotan [32]

Answer:

25

Step-by-step explanation:

If 5/8 are boys then

1 - 5/8 = girls

3/8 = girls

3/8 of the total are girls

Let x = total

3/8 ( x) = 15

8/3 * 3/8 * x = 15 * 8/3

x = 40

There are 40 total students

5/8 are boys

5/8 * 40

25 are boys

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.

Inga [223]

Answer:

length = 15

breadth = 25

Step-by-step explanation:

length = breadth + 10

let length be x

length = x

breadth = x + 10

perimeter = 2(length) + 2(breadth)

80 = 2(x) + 2(x + 10)

80 = 2x + 2x + 20

80 = 4x + 20

80 - 20 = 4x

60 = 4x

15 = x

length = x = 15

breadth = x + 10 = 25
