What problem led to playgrounds becoming more common in America cities

<h2>Answer:</h2>

$x = \frac{22}{3}$

<h3>alternative form:</h3>

$x = 7 \frac{1}{3} \: or \: x = 7.33333333333$

<h2>Step-by-step explanation:</h2>

$2(3x + 1) = 17 - 3( x - 17) \\ distribute \\ \\ 6x + 2 = 17 - 3x + 51 \\ add \: 3x \: from \: both \: sides \\ \\ 9x + 2 = 17 + 51 \\ add \: 17 \: to \: 51 \\ \\ 9x + 2 = 68 \\ subtract \: 2 \: from \: both \: sides \\ \\ 9x = 66 \\ divide \: both \: sides \: by \: 9 \\ \\ x = \frac{22}{3}$

A line segment has endpoints at 3,2 and 2,-3 which reflection will produce an image with endpoints at 3,-2 and 2,3

xenn [34]

Answer:

The reflection is across the x-axis

Step-by-step explanation:

* Lets revise the reflection

- If point (x , y) reflected across the x-axis

∴ Its image is (x , -y)

- If point (x , y) reflected across the y-axis

∴ Its image is (-x , y)

- If point (x , y) reflected across the line y = x

∴ Its image is (y , x)

- If point (x , y) reflected across the line y = -x

∴ Its image is (-y , -x)

* Now lets solve the problem

∵ The endpoints of a line segment are (3 , 2) and (2 , -3)

∵ The image of the endpoints after the reflection are (3 , -2) and (2 , 3)

* Lets study the change

# The x-coordinates of the points are 3 and 2

# The x-coordinates of the images are 3 and 2

# The y-coordinates of the points are 2 and -3

# The y-coordinates of the images are -2 and 3

- The change is in the signs of the y-coordinates

∴ The reflection is across the x-axis

Solve the two-step equation. -9x + 0.4 = 4 Which operation must be performed to move all the constants to the right side of the

Alexandra [31]

Answer:

x = -0.4

Step-by-step explanation:

We have the equation:

-9x + 0.4 = 4

First, the operation to move all the constants to the right side is subtraction since we would have to subtract 0.4 from each side, let's see this:

$-9x+0.4=4\\-9x+0.4-0.4=4-0.4\\-9x=3.6$

Now, we have all the constants on the right side of the equation.

Now, the operation we need to perform to isolate the variable is division (since the x has a -9 that is being multiplied by x) we need to do the opposite operation:

$-9x=3.6\\\frac{-9x}{-9} =\frac{3.6}{-9} \\x=-0.4$

<h3>Thus, the answer to this equation is x= -0.4</h3>
