Answer:

x = 4

Step-by-step explanation:                            

[ changing sides, changes addition to subtraction and subtraction to addition] [ multiplication changes to division and division changes to multiplication]

3x -5 =7  

3x = 7 + 5

3x = 12

x = 12/3

x = 4

Answer:

x=4

Step-by-step explanation:

3x-5 = 7

Add 5 to each side

3x-5+5 = 7+5

3x = 12

Divide each side by 3

3x/3 = 12/3

x = 4

Which transformations map the strip onto itself?
Pie

Answer:

<h2>A horizontal translation and a 180° rotation only.</h2>

Step-by-step explanation:

Notice those shapes are positioned as a reflection.

So, one way to map them onto is self is by rotating 180° and a horizontal translation. Or it could work if we translate it horizontally, the we reflect it vertically. Those transformations would map the strip onto itself.

Therefore, the second choice is the best answer.

What is the justification for each step in the solution of the equation?
otez555 [7]

23x-13=2(x+2)

First you would distribute the 2 into the parenthesis

It will look like this after: 23x-13=2x+4

Then you would subtract 2x on both sides because u have to get the x's on one side

It will look like this after:21x-13=4

Then you would add 13 to both sides

It will look like this after: 21x=17

Then you would divide 21 on both sides

Your final product is 21/17
