What is the solution to the system of equations?

2x+y=11
1/2x-5y=8

please help!!!

Answers

Answer: ( x,y ) = ( 96/43, 152/43 )

Step-by-step explanation:

Answer: ( x,y ) = ( 96/43, 152/43 )

Step-by-step explanation:

rewrite the expression

2x + y=8

11 1/2 x X - 5y=8

mixed fraction btw.

simplify

2x + y =8

23x - 10y = 16

multiply both sides

20x + 10y = 80

23x - 10y = 16

eliminate one variable by adding the equations

43x =96

divide both sides

x = 96/43

substitute the value of x

2 x 96/43 + y = 8

solve the equation

y = 152/43

a possible solution is

( x,y ) = ( 96/43, 152/43 )

check solution

simplify

8 = 8 = 8

the ordered paired is a solution!

final answer: ( x,y ) = ( 96/43, 152/43 )

rewrite the first equation as y = -2x+11
plug in this equation into the second equation
solve for x
x=6

plug x=6 into the first equation
solve for y
y=-1

THE ANSWER IS (6,-1)

Answers

Answer:

5 points for 5 sentences?! not being greedy but like...

Step-by-step explanation:

Yes, they are. Congruence are two objects, doesnt matter if its two dimensional or three dimensional. They are all identical in size and shape. In geometry, congruent figures have three properties: 1. The same size. 2. Same shape. 3. Parts that are corresponding are congruent. One example are ches peices, A knight is on a high shelf, the other a low shelf, Just because they are in different planes of three dimensions does NOT mean it rules out their congruence.

Answer:

[tex]6[/tex] square units

Step-by-step explanation:

The area of a triangle can be calculated by multiplying the triangle's base by its height, and then dividing the result by [tex]2[/tex]. As an algebraic expression, this would be [tex]\frac{bh}{2}[/tex], where [tex]b[/tex] is the triangle's base and [tex]h[/tex] is the triangle's height. In this case, we know that [tex]b=3[/tex] and [tex]h=4[/tex]. Therefore, the area of this triangle is [tex]\frac{3*4}{2} =\frac{12}{2} =6[/tex] square units. Hope this helps!

the area is 6 units.

the area of the parallelogram shown is 9 square inches set up and solve an equation to find the value of

Answers

ANSWER: X = 45
First, you have to set up the equation.
If the area of the square is 9, and one side is 3 square units, then the other side must also be 3 units because 3X3=9.
When finding the value of a variable, you ALWAYS want to get the variable alone on one side.
So now, you take the equation, 1/9x-2 and make is equivalent to 3.
1/9x-2=3
Now, to simplify, you add to to undo the -2, and add 2 to the 3
1/9x-2(+2)=3+2
So now the equation is 1/9x=5
To undo a fraction, think of it as a division problem. To undo a division problem, you must multiply the fraction by the denominator.
1/9x(9)=5(9)
5X9 is 45
So the answer is X=45
And is you want to check it:
1/9(45)-2=3
1/9X45 is 45/9 or 5
5-2=3
3=3
The answer is X=45

If the area of the parallelogram shown is 9 square inches. The value of x will be 45.

What is parallelogram?

In two-dimensional geometry, it is a plane shape having four sides, in which two pairs of sides are parallel to each other and equal in length. The sum of all angles in a parallelogram is 360°. Similar to how the area of a rectangle is calculated, the formula for calculating the area of a parallelogram is base times height.

It is given that the sides of the parallelogram are (1/9x-2) and 3 and the area is 9 square inches.

The area of the parallelogram will be the product of their sides as,

Area = Side A × Side B

A =  (1/9x-2) 3

9 = 1/3x-6

Simplify the equation to find the value of x,

9+6 = 1/3x

15=1/3x

x=45

Thus, if the area of the parallelogram shown is 9 square inches. The value of x will be 45.

A jar contains n nickels and d dimes. There are 20 coins in the jar, and the total value of the coins is $1.50. How many nickels and how many dimes are in the jar?

The jar contains ___ nickels and ___ dimes.

Answers

Answer:

The jar contains 10 nickels and 10 dimes. Another answer is that the jar contains 4 nickels and 13 dimes.

Step-by-step explanation:

1 nickels = 5 cents

1 dime = 10 cents

1st answer

10 nickels = $0.50

10 dimes = $1.00

So 10 nickels + 10 dimes = $1.50

2nd answer

13 dimes = $1.30  

4 nickels = $0.20

So 13 dimes + 4 nickels = $1.50

10 nickels and 10 dimes

Step-by-step explanation:

The blue portion of the American flag is known as the union. Using the measurements in the diagram, determine if the rectangle enclosing the union is similar to the rectangle enclosing the entire flag.

Answers

They are not similar.

The dimensions of the Union are 3'x5'.

The dimensions of the overall flag are 9-1/2'x5'.

Hope this helps ^^

The rectangle enclosing the union is not similar to the rectangle enclosing the entire flag.

Given that the flag's union portion has dimensions = 18.24 in and 13 in, whereas the entire flag has the dimension = 3.8 ft and 2 ft,

We need to check if the rectangle enclosing the union is similar to the rectangle enclosing the entire flag.

To determine if the rectangle enclosing the union portion of the flag is similar to the rectangle enclosing the entire flag, we can compare their aspect ratios.

The aspect ratio of a rectangle is calculated by dividing its longer side by its shorter side.

In this case, for the union portion of the flag, the longer side is 18.24 inches, and the shorter side is 13 inches.

Thus, the aspect ratio of the union rectangle is:

Aspect ratio of union rectangle = 18.24 in / 13 in ≈ 1.403

For the entire flag, the longer side is 3.8 feet (which is equivalent to 45.6 inches) and the shorter side is 2 feet (which is equivalent to 24 inches). Therefore, the aspect ratio of the rectangle enclosing the entire flag is:

Aspect ratio of entire flag rectangle = 45.6 in / 24 in ≈ 1.9

Since the aspect ratios of the two rectangles are different (1.403 vs. 1.9), we can conclude that the rectangle enclosing the union portion of the flag is not similar to the rectangle enclosing the entire flag.
