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.

#SPJ2

Find the area of a triangle with a base length of 3 units and a height of 4 units.

Group of answer choices

3 units

6 units

7 units

8 units

Answers

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!

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

How to find mode:

To find mode what you do is find the number that is the most common in the number group. In this case, there was one 3, three 7's, one 2, one 4, one 5, one 1, and two 8's. And since there was the highest amount of 7's, 7 was the mode.

How to find median:

To find the median, you line the numbers up from smallest to greatest and find the middle number, since this was a even number, there were two center numbers which were 5 and 7, after finding those, you add 5 and 7 together and divide that by two. So the equation would be (5+7)÷2=6

How to find mean:

To find the mean, you add all of the numbers together then divide it by the amount of numbers there are. The equation would be: (3+7+2+4+7+5+7+1+8+8)÷10=5.2

How to find range:

To find the range you do the largest number minus the smallest number. In this case it would be 8-1=7.
