Answer:

1/6

Step-by-step explanation:

Step 1: Subtract 9x from both sides.

3x+4−9x=9x+3−9x

−6x+4=3

Step 2: Subtract 4 from both sides.

−6x+4−4=3−4

−6x=−1

Step 3: Divide both sides by -6.

−6x                  -1

-------      =     ----------

-6                    -6

Answer:

                  x = 1/6 =0.167

Step-by-step explanation:

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    3*x+4-(9*x+3)=0  

Step by step solution :

Step  1  :

Solving a Single Variable Equation :

1.1      Solve  :    -6x+1 = 0  

Subtract  1  from both sides of the equation :  

                     -6x = -1

Multiply both sides of the equation by (-1) :  6x = 1

Divide both sides of the equation by 6:

                    x = 1/6 = 0.167

One solution :

                  x = 1/6 = 0.167

A square has a perimeter of 12x + 52 units. Which expression represents the side length of the square in units?
Yuki888 [10]
The perimeter of a square is the sum of its sides.
 Then the perimeter is
 P = 4L
 Clearing the side we have:
 L = (P / 4)
 L = (12x + 52) / 4
 L = 3x + 13
 answer:
 The side length of the square is 3x + 13 units

Answer:

See below.

Step-by-step explanation:

<u>Question 1</u>

a = -2 and x = -6

| a + x | / 2 - | a - x | / 2

| -2 + -6 | / 2 - | -2 + 6 | / 2

| -8 | / 2 - | 4 | / 2

8/2 - 4/2

= 4/2

= <u>2</u>

<u></u>

<u>Question 2</u>

a = -5, b = 4, c = 1, d = -3

| a - b | - | c + d |

| -5 - 4 | - | 1 - 3 |

| -9 | - | -2 |

= 9 - 2

= <u>7</u>

Solve for the mean and median of the following data: 20, 10, 15, 18, 12, 17
loris [4]
<h2><u>Mean and Median</u></h2>

<h3>solve for the mean and median of the following data: 20, 10, 15, 18, 12, 17</h3>

<h3><u>Mean</u></h3>

To find the mean of a data set, use the formula:

<u>mean</u> = <u>sum of the data points</u>/<u>number of the data points</u>

We will determine the sum of the data points.

  • 20 + 10 + 15 + 18 + 12 + 17 = 92

Since the number of data points is 6, we will divide the sum and the number of data points as shown in the formula above.

  • 92/6
  • 15.3

<u>Answer:</u>

  • The mean of the data set is <u>15.3</u>.

<h3><u>Median</u></h3>

To find the median of the data set, arrange the data set into ascending order and the value in the middle is the median. The median should be an even number.

  • 20, 10, 15, 18, 12, 17
  • 10, 12, 15, 17, 18, 20

The middle value is 15 and 17. Find out their sum and divide it into 2.

  • 15 + 17/2
  • 32/2
  • 16

<u>Answer:</u>

  • The median of the data set is <u>16</u>.

olga nikolaevna [1]

Answer:

10 ft

Step-by-step explanation:

perpendicular (p)= 6 ft

base(b) =8 ft

hypotenuse (h) = ?

we know by using Pythagoras theorem

h = \sqrt{p^{2}+b^{2} }

= \sqrt{6^{2}+8^{2}  }

= 10 ft

hope it helps :)
