x+3y=0 and 12y=-4 equation plz help.

Answers

Answer 1

Answer:

[tex]x = 1[/tex] and [tex]y = -\frac{1}{3}[/tex]

Step-by-step explanation:

So we can equate the second equation in terms of y by dividing both sides by 12:

[tex]y = -\frac{1}{3}[/tex]

Let us substitute this into the first equation:

[tex]x + 3y = 0[/tex]  

then becomes  

[tex]x + 3(-\frac{1}{3} ) = 0[/tex]

which simplifies to

[tex]x - 1 = 0[/tex]

Finally solving for x gives us:

[tex]x = 1[/tex]

Therefore, [tex]x = 1[/tex] and [tex]y = -\frac{1}{3}[/tex]

Hope this helps!

Brainliest please!

Answer 2

Answer:

x=1, y=-1/3

Step-by-step explanation:

x+3y=0

12y=-4

12y=-4

y=-1/3

x+3y=0

x+3(-1/3)=0

x-1=0

x=1

The diagonals of a kite are 21cm and 11cm. Find the perimeter of the kite.

Answers

Answer:

Perimeter: 64 cm

Step-by-step explanation:

21 + 21 = 42 cm 11 + 11 = 22 cm

42 + 22 = 64 cm

Answer: 64 cm

Step-by-step explanation:

You get the value of the perimeter by adding up all the four sides of the kite. Kites typically have 4 sides, and 2 equal sides, this means that there are two sides of the kite which are 21 cm long, and 2 sides that are 11 cm long. This represented as an expression would be 21+21+11+11, which would simply equal to 64 cm

opposite sides parallel and congruent theorem,
parallelogram diagonals converse

Answers

Answer:  parallelogram diagonals converse

Explanation:

The parallelogram diagonals theorem says that if you have a parallelogram, then the diagonals bisect each other. This means the diagonals cut each other in half. Furthermore, it also means the two diagonals meet at the midpoint of each diagonal.

The converse takes this in reverse. If we know the two diagonals cut each other in half, then this must mean we are dealing with a parallelogram.

We can prove this by showing that triangle EHF is congruent to triangle GHD, where H is the intersection of the two diagonals. We use SAS in this case. From there, we then can see that the corresponding pieces of the two triangles are congruent. This leads to the alternate interior angles being congruent. The last piece of the puzzle is the alternate interior angles theorem converse, which shows the opposite sides EF and DG are parallel. A similar proof occurs to show that ED is parallel to FG.

What integer describes 75 feet above sea level?

Answers

Answer:

75

Step-by-step explanation:

Sea level is considered 0. To find 75 feet above sea level, we add 75 to 0. This gets us 75. Since 75 is an integer, it checks out.

The required integer would be 75 which describes 75 feet above sea level.

What are Integers?

Integers are defined as the collection of Whole Numbers and the negative values of Natural Numbers make up an integer. Fractional numbers are not included in integers. Integers are represented by the symbol Z.

What are Arithmetic operations?

Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.

Let the sea level would be considered zero.

To determine 75 feet above sea level,

We have to add 75 to 0.

⇒ 75 + 0

⇒ 75

This obtains us 75.

Since 75 is an integer.

Therefore, the required integer would be 75 which describes 75 feet above sea level.

A store pays $ 23 for each umbrella. The store marks the price at 50%. What is the quantity of the mark?

Answers

Answer:

11.5 or 34.5 in total..

Answer:

The quantity of the mark is $11.5.

Step-by-step explanation:

The cost of each umbrella = $23Markup percentage = 50%

The quantity of the mark can be determined by multiplying the cost of the umbrella by the markup percentage.

Thus,

The quantity of the mark = 23 × 50%

                                          = 23 × 50/100

                                           = 23 × 1/2

                                            = 23 × 0.5

                                             = $11.5

Therefore, the quantity of the mark is $11.5.

Step-by-step explanation:

If a T-Shirt Launcher can launch 6 shirts in 30 minutes, that means it can launch 12 shirts in an hour, because there are 60 minutes in a hour, and 30 minutes is half os 60 minutes, so we just do 6 x 2 = 12.

Answer:

There are 12 shirts launched in an hour.
