Cerrena [4.2K]3 years ago

Answer:

A

Step-by-step explanation:

Start with variable x.
4x - 6y = 28
Substitute the variables for numbers.
4(1) - 6(-4) = 28
Solve the new equation
4 + -24 = 28

Move to the second equation with variable y.
8x - 4y = 24
Substitute variables
8(1) - 4(-4) = 24
Solve
8 - (-16) = 24

The answer is A, x = 1, y = -4

If two angles of one triangle equal in measure to two angles of another triangle then the third angles of the triangle
Vika [28.1K]

Answer:

Are also equal

Step-by-step explanation:

Say triangle A has the angles 30 and 60. triangle b also has those angles. Total angle of any triangle is 180 so 180-60-30 = 90 for triangle A and it is also the same for triangle b. Thus 90 = 90 angles are the same.

That's the question ?? ​
Oksanka [162]

Step-by-step explanation:

Before we answer, the area of a Circle given it radius is

a = \pi r {}^{2}

The area of a circle given it diameter is

a =  \pi( \frac{d}{2} ) {}^{2}

So let answers question 1-4.

1. The area is

1024\pi

2. The area is

576\pi

3.

1.225\pi

4.

309.76\pi

For the 5th problem, circumference is

\pi \times d

where d is the diameter and

2\pi  r

where r is the radius.

A circumference of 100 m means the radius is 50 because

2\pi \times r = 100\pi

r = 50

So this means the area is

2500 {\pi}
