6x-3y=3
-2x+6y=14.
First step is multiply the top equation by 2, so you have
12x-6y=6
-2x+6y=14
-6y and +6y cancel each other out, so if you simplify, you have
10x=20, which is then solved by dividing each side by 10, and getting x=2.

Now plug x=2 into one of the equations (I chose the first)
6(2)-3y=3
12-3y=3
-3y=-9, divide each side by -3 and get y=3.
so your point is (2,3)

Answer:

1.    0.83 = 83%

2.    6.1% = 0.061

Step-by-step explanation:

The answer in number one is because when you're trying to find a percentage from a decimal, all you have to do is multiply your decimal by 100, this is because a percentage is always out of 100.

The answer in number two is exactly the opposite, all you have to do is divide by 100 if you are trying to find your decimal from a percentage.

Answer:

Option 3rd is correct

No,

she should have added 6^2 and 8^2 and compared that to 10^2

Step-by-step explanation:

In a right angle triangle, we use Pythagorean theorem.

Pythagorean theorem states that

the sum of the squares of two sides must equal the square of the third side(the side facing the right angle).

i.e,  \text{Hypotenuse side}^2=\text{sum of the square of two side}

Given a triangle with side lengths 6, 10, and 8.

If we square all the given sides, we get;

6^2 = 36,

8^2 = 64

10^2=100

It can be seen that the sum of 36 and 64 is 100

⇒6^2+8^2 = 10^2

which satisfies the Pythagorean theorem.

⇒ The triangle is right-angled with the side lengths 6 units and 8  units forming the right angle and the side length 10 units  being the hypotenuse.

Therefore, her answer is incorrect, she should have added 6^2 and 8^2 and compared that to 10^2
