edc is on the same lame
anonymous
  • anonymous
OK. sorry. But is the line below the same length as the one above it?
anonymous
  • anonymous
Well The Top One Says 8 . & The Bottom Says 13.
anonymous
  • anonymous
Ok. So lets assume they both are of same length. and we'll name the line below KL...just for easy referencing, okay?

And that D is the midpoint..

Yeah sure :)

OK so both lines KL and EC are of same length 13 and ED is 8. But we need to find DC
anonymous

k
anonymous
  • anonymous
But you answer is correct....
anonymous
  • anonymous
is it ?
anonymous
  • anonymous
Yeah it is.. I'm guessing you need help with number 5?
anonymous
  • anonymous
yes lol
anonymous
  • anonymous
ok so we could make an equation for it. You know how to do that?
anonymous
  • anonymous
x+10=2x+19
anonymous
  • anonymous
Almost. you have to include the 9 also
anonymous
  • anonymous
how ?
anonymous
  • anonymous
x + 10 + 9 = 2x + 19
anonymous
  • anonymous
Although you don't need the length of VU you still have to include in order to make the line VUT= to the line below it. Make sense?
anonymous
  • anonymous
yes
anonymous
  • anonymous
OK so then now you can solve it?
anonymous
  • anonymous
Bring all the like terms together and remember that if a term crosses the equal sign the sign in front of it changes
anonymous
  • anonymous
Can u help with that @kalahkid
anonymous
  • anonymous
Sure. So the equation is 2x + 19 = x + 10 +9. we want to move all the x terms to the left side and all the terms without x to the right side
anonymous
  • anonymous
Ok.
anonymous
  • anonymous
Do I Add 2x To Both Sides
anonymous
  • anonymous
No. What you do is take the x from the right side and bring it to the left side
anonymous

  • anonymous
Oh That Makes Sense.
anonymous
  • anonymous
OKay. Now you do the rest
anonymous
  • anonymous
Now Can I Sub . 2x
anonymous
  • anonymous
No you're not subtracting anything. Just moving from one side to the other and changing the sign. The 19 on the left side has to move to the right side. Try that
anonymous
  • anonymous
2x + -1x =1x 19+1x=10+9
anonymous
  • anonymous
@kalahkid Yes ?
anonymous
  • anonymous
2x + 19 = x + 10+ 9
anonymous
  • anonymous
when we move all x terms to left side and terms without x to right side we get 2x - x = 10 + 9 - 19
anonymous
  • anonymous
Understand?
