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.

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:

the volume of this pyramid is 4,480ft³

Step-by-step explanation:

The formula for a rectangular pyramid is V = 1/3 (lw)(h) you can also think about it like this V = 1/3 (l)(w)(h)

V= (l)(w)(h)

1. multiply 17.5, 32, and 24.

17.5 × 32 × 24 = 13,440

2. after you multiply divide the answer by three

13,440 ÷ 3 = 4,480

If you are not sure you divided correctly you can always multipy and 4,480 × 3 = 13,440.

So this pyramid is 4,480ft³.

I also want to add that sorry that people were mean to you, and also I will write the formulas to find volume for the rectangular pyramid and triangular pyramid below, so you cab have them, hope this helps and I hope you are feeling better.

Rectangular Pyramid Formula:

V = 1/3 (lw)(h) or V = 1/3 (l)(w)(h)

V= (l)(w)(h)

Triangular Pyramid Formula:

when you get a Triangular pyramid you should get two numbers at the base and when you do, you have to multiply them and if you want divide the answer by 2. Then, you multiply what you divided by height and once you get your answer divide by three. This is the complicated way to do it.you can also do it by multiplying the two numbers at the bases and the height and after you multiply the three answers you divide by 6.

V = 1/3 (1/2 bh)h

You can divide by 6 after mtuplying the 2 numbers at the base and the height because 2 times 3 equals 6.

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

[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!
