Answer:

All steps are correct

Step-by-step explanation:

|2x − 5| − 2 = 3

Step 1

|2x − 5| = 3 + 2  (adding 2 on both sides)

Step 2

|2x − 5| = 5  

Step 3

2x − 5 = 5 or 2x − 5 = −5   (on opening the modulus, we get 2 cases)

Step 4

2x = 10 or 2x = 0   (adding 5 on both sides)

Step 5

x = 5 or x = 0   (dividing by 2 on both sides)

Hence, each step was correct

|2x - 5|  - 2 = 3    |add 2 to both sides

|2x - 5| = 5

2x - 5 = 5 or 2x - 5 = -5    |add 5 to both sides

2x = 10 or 2x = 0    |divide both sides by 2

x = 5 or x = 0

All steps are correct.

Not sure how to do this. (I'm aware this is wrong lol)
Bezzdna [24]
I think the answer is 80 degrees. Think about it like you're moving the chunk with 100 degrees already filled in, to the space where you're trying to find the amount since they're the same. Vertical angles are supplementary and are equal to 180. So, 100+x = 180. x would equal 80 degrees.

Use factoring to simplify the expression x^2-x-6/x-3 assume that x does not equal 3
Gre4nikov [31]
This works out beautifully.  You COULD use long division here, but since your numerator is a quadratic, your first instinct should be to try and factor it.  If you factor it, it works out to be (x - 3)(x + 2).  Now it just so happens that when you do that, the (x - 3) in the numerator will cancel with the (x - 3) in the denominator leaving you with one sad and lonely (x + 2) as your answer.
