I really need your help please !?

Question

do you understand this? well what does the lines mean that are with the 15? by the way its pre-algebra and I'm confused. i asked my mom but she doesn't know either . thanks

equation is...

|15| _15 ( we have to tell if its <,>, or =. but i cant figure out what the lines mean! ps the blank is the space to put the <,>,= incase that confuses you.

thanks soo much

Answer 1

The number inside the lines is the number of spaces away from zero.  It&#039;s called absolute value.  Ignore any positive or negative symbols, and just pay attention to the number itself.  The answer is = because 15 is the same distance away from 0 as 15 because they are the same.  

Answer 2

Hi,

It is very simple.

You may have known that the below mentioned equation.

|a| = a

|-a| = a

So, there will be always 15 = |15|

So, your answer is

|15| = 15

Answer 4

The bars mean Absolute value.

|12| is 12, as is |-12| It would still be 12.

So |15|=15 because the absolute value of 15 is 15. Even if it was |-15| it would still be an equal sign, because the absoulte value of -15 is 15.

Hope this helped. Good Luck!!

Answer 5

=

the bars mean that anything inside of them is positive

Ex: |2-7|=5  ----- on problems like this 1... it is more like |(2-7)|

|-4|=4
