i used a calculator

Answer: X = 1/7

Step-by-step explanation:

37x = 9x + 4

subtract 9x to both sides

28x = 4

now divide by 28

x = 4/28

simplified its

x = 1/7

Answer:

28x=4

x=1/7

Step-by-step explanation:

First you would make simplyfiy the expression so that you would have x on one  side, when you do that you will get 28x=4. When simplyfied you will get 1/7.

Given:

An hour before showtime only 105 people have arrived for a concert.

According to sales 95% of the people have yet to arrive.

To find:

The total number of tickets sold.

Solution:

Let x be the total number of tickets sold.

According to sales 95% of the people have yet to arrive.

[tex]100\%-95\%=5\%[/tex]

It means, only 5% people have arrived.

[tex]\dfrac{5}{100}x=105[/tex]

[tex]\dfrac{1}{20}x=105[/tex]

[tex]x=105\times 20[/tex]

[tex]x=2100[/tex]

Therefore, the total 2100 tickets were sold.

Answer:

16

Explanation:

First you convert  

80

%

into a decimal which is  

.80

then you multiply it by  

20

.

.80

×

20

=

16

We multiply it by  

20

because that's our total and by  

.80

because that's the amount that we got correct. Had it been  

100

%

then that would mean we got every question right.

Step-by-step explanation:

pythagorean theorem

take the sum of the square of each leg and set it equal to the square of the hypotenuse

8² + 6² = x²

64 + 36 = x²

x² = 100

x = [tex]\sqrt{100}[/tex] or 10

Answer:

B.10 units

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem which states that a^2+b^2=c^2

Plug in what we know....

8^2+6^2=c^2

64+36=c^2

c=sqrt(100)

c=10 units or B

Answer:

m EAD = 56

m EDA = 35

x = 4

Step-by-step explanation:

In a parallelogram, the diagonals bisect each other. This means that AE and EC are equal. To find x, simply set 2x + 3 = 11, and solve.

2x + 3 = 11

2x = 8

x = 4

Additionally, since the sides of a parallelogram are parallel, BC + AD are parallel, as are AB + DC. This make ECB + EAD and EBC + EDA opposite interior angles (have same measure). Thus, since we know ECB = 56 and EBC = 35, EAD also = 65 and EAD also = 35

Answer:

Rotations, Reflections

Step-by-step explanation:

This is going to be our answer because we know that a figure has some kind of rotation.

A rotation is when a shape can be rotated in some way. A reflection is a transformation representing a flip of a figure. Figures may be reflected in a point, a line, or a plane. When reflecting a figure in a line or in a point, the image is congruent to the preimage. A reflection map every point of a figure to an image across a fixed-line.

So our answer would be Rotations, Reflections!

35

Step-by-step explanation:

Please look at the attachment down below.

Hope this helped! :)

The  sum of three number is 35.

A square number is the result when a number has been multiplied by itself.

For example, 25 is a square number because it's 5 lots of 5, or 5 x 5.

Given:

if the number given is 9

9² - (9 - 1)² = 9² - 8²

                 = 81-64

                  = 17.

if the number given is 6.

6² - (6 - 1)² = 6² - 5²

                 = 36-25

                 = 11.

if the number given is 4.

4² - (4 - 1)²= 4² - 3²

                = 16-9

                = 7.

Thus, the sum of three number is

=17 + 11 + 7

= 35

Step-by-step explanation:

Decreasing: A function is decreasing, if as x increases (reading from left to right), y decreases. In plain English, as you look at the graph, from left to right, the graph goes down-hill. The graph has a negative slope

So in given graph ,

Decreasing interval are ,

Answer:

b = 6

Step-by-step explanation:

Let's solve for b.

(3x−1)2=9x2−bx+1

Step 1: Flip the equation.

−bx+9x2+1=9x2−6x+1

Step 2: Add -9x^2 to both sides.

−bx+9x2+1+−9x2=9x2−6x+1+−9x2

−bx+1=−6x+1

Step 3: Add -1 to both sides.

−bx+1+−1=−6x+1+−1

−bx=−6x

Step 4: Divide both sides by -x.

b = 6
