In mathematics, a set of simultaneous equations, also known as a system of equations or an equation system, is a finite set of equations for which common solutions are sought.

(1) Systems of equations

2x + y = 12

x = 9 − 2y

See the graph given below the solution is the point (5,2).

(2) Systems of equations

x + 2y = 9

2x + 4y = 20

See the graph given below the solution is the point has no solution the two lines are parallel.

(3) Systems of equations

x + 3y = 16

2x − y = 11

See the graph given below the solution is the point (7,3).

(4) Systems of equations

y = 11 − 2x

4x − 3y = -13

See the graph given below the solution is the point (2,7).

(5) Systems of equations

y = 10 + x

-3x + 3y = 30

See the graph given below the system has no solutions.

(6) systems of equations

2x + y = 11

x − 2y = -7

See the graph given below the solution is the point (3,5).

Therefore, the solutions to the system of equations are given below in the figure.

#SPJ5

Answer:

Carla ran 0.1 miles per minute.

Step-by-step explanation:

To solve this, we need to use the distance formula.

The formula is d=rt, where d is the distance traveled, r is the rate in which the distance is traveled, and t is the amount of time it took to go that distance. So lets plug it all in.

d=rt

3=(r)(30)

Now, we need to do the inverse of multiplying 30 to both sides, which would be the same as dividing by 30 on both sides.

3/30=(r)(30/30)

0.1=r

The rate is 0.1. Carla ran 0.1 miles per minute.

Answer:6200

Step-by-step explanation:

:We round the number up to the nearest hundred if the last two digits in the number are 50 or above.

: We round the number down to the nearest hundred if the last two digits in the number are 49 or below.

: If the last two digits are 00, then we do not have to do any rounding, because it is already to the hundred.

:In this case, Rule B applies and 6248 rounded to the nearest hundred is:

Answer:

Step-by-step explanation:

To solve for x you have to move the -5y to the other side of the equals sign.  Since the opposite of subtracting is adding, we will add 5y to both sides to get

x = 5y + 6

Answer:

In the audience, there are 90 adults and 54 children

Step-by-step explanation:

If we have 5 adults for every 3 children, we would continue this pattern by saying we have 10 adults for every 6 children, 15 adults for every 9 children, and so on.

We can express this situation into an equation by saying 5x + 3x = 144

8x = 144

x = 18

So now we know there are 5(18) = 90 adults for every 3(18) = 54 children

In the audience, there are 90 adults and 54 children

Answer: 12

Step-by-step explanation:

I will assume those are coordinates.

The distance between 2 points is given by  √ (x2 − x1)^2 + (y2 − y1)^2.

Replacing the values, we get  √ (5 − 5)^2 + (6 − -6)^2 =  √0+144 = 12

#LearnWithEXO

Answer:

2hrs 30 mins on Friday or 2:30 in the afternoon on Friday

Step-by-step explanation:

it took the aero plane 8 h 45 minutes to travel

it reached its destination at 6 : 15 on Friday

to find the time and day it started, we just subtract the time it used to travel from the time and day it landed

which is;

8 45

-6 15

=2 30

that is 2hrs 30mins on Friday

Answer:

JK = 42 , KL = 78

Step-by-step explanation:

JK + KL = JL , substitute values

4x + 6 + 7x + 15 = 129 , that is

11x + 21 = 120 ( subtract 21 from both sides )

11x = 99 ( divide both sides by 11 )

x = 9

Then

JK = 4x + 6 = 4(9) + 6 = 36 + 6 = 42

KL = 7x + 15 = 7(9) + 15 = 63 + 15 = 78

Answer:

$223,600

Step-by-step explanation:

1. Multiply 520000 by 0.19 and get an answer of 98800. This is how much by which the car depreciates every year.

2. Now multiply 98800 by 3 (years). Now your answer would be 296400.

3. Now minus the depreciated value from the original value which is 520000-296400=223600.

Not sure about the answer but I hope this helped a bit

Answer:

$3,567.00

Step-by-step explanation:

Here is how I got it!

First, you will have to borrow the 520,000 from the word problem.

Next, multiply 520,000 with 0.19 with the power of 3

[tex]520,000*0.19^3=n[/tex]

The 3 is the number of years, n is the nearest $ answer.

--

First, do [tex]0.19^3[/tex]

[tex]0.19*0.19*0.19=0.006859[/tex]

(Again, that's a crazy number!)

--

With 0.006859, multiply it with 520,000

[tex]520,000*0.006859=3566.68[/tex]

3566.68 is technically (in money) $3,566.68 (with .68 being sixty-eight cents).

--

Finally, it states to answer to the nearest $.

Just round up the .68 to 1 dollar which will just add one more dollar to 3,566

[tex]3,566.32[/tex] ⇒ [tex]3,567.00[/tex] (since .32 is below .50, you can't round it UP)

Add you $ symbol

With the result being: $3,567.00

Answer:

A) you would divide $128 by 4, getting $32. then add that to the original price, being $160.

B) you would divide $160 by 2, getting $80, then add those two together in order to find what it was marked up to, is $240. hopeful, this helps
