Is Line EC and KL the same length?
There Is No K .
Those Are Arrows.
edc is on the same lame
OK. sorry. But is the line below the same length as the one above it?
Well The Top One Says 8 . & The Bottom Says 13.
Ok. So lets assume they both are of same length. and we'll name the line below KL...just for easy referencing, okay?
Long As I Dont Get Confused Im Fine . Matter Of Fact Will A Picture Work ?
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
But you answer is correct....
is it ?
Yeah it is.. I'm guessing you need help with number 5?
ok so we could make an equation for it. You know how to do that?
Almost. you have to include the 9 also
x + 10 + 9 = 2x + 19
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?
OK so then now you can solve it?
Bring all the like terms together and remember that if a term crosses the equal sign the sign in front of it changes
Can u help with that @kalahkid
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
Do I Add 2x To Both Sides
No. What you do is take the x from the right side and bring it to the left side
Oh That Makes Sense.
OKay. Now you do the rest
Now Can I Sub . 2x
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
2x + -1x =1x 19+1x=10+9
@kalahkid Yes ?
2x + 19 = x + 10+ 9
when we move all x terms to left side and terms without x to right side we get 2x - x = 10 + 9 - 19
