Is this two segments of the same line? Are these line segments congruent or is there a total length for the line?

Then you also need to know the distance of KM or the ratio of KL to LM. Either way, more information is required.

set up a system of equations

It just says find the value and it gives you what i drew..

Can you provide a picture?

I just did, did you not get it?

these should be inequalities not = signs

Thats what it says :/

I meant a photograph of the original question. Something is missing or not written accurately. @timo86m may be right about the inequality.

I don't have to do 11, but i have to do 10 and 12.

use proportions :)
anonymous
  • anonymous
It doesn't state it, but it looks like the two line segments are equal.
anonymous
  • anonymous
So set both equation equal to each other and solve for x.
anonymous
  • anonymous
How do i use proportions? I'm so so but im quite confused.
anonymous
  • anonymous
sorry*
anonymous
  • anonymous
oh they 1 to 1 so as gypsy said let them equal each other :)
anonymous
  • anonymous
how would i do that?
anonymous

3x + 2 = 5x - 10
anonymous
  • anonymous
Put on expression on one side of the equal sign and put the other on the other side of the equal sign as Timo just demonstrated.
anonymous
  • anonymous
Can you give me an example?
anonymous
  • anonymous
Tim just did.
anonymous
  • anonymous
:D i sure did
anonymous
  • anonymous
but i dont understand what i would do after that.

Combine like terms.
anonymous
  • anonymous
Use inverse operations - if a term is positive, subtract it from both sides.
anonymous
  • anonymous
Get all the x terms on one side and the constant terms (numbers without variables) on the other side.

From the graph on your paper we can tell kl=lm there fore 3x + 2 = 5x - 10 3x+2-2=5x-10-2 subtract 2 from both sides. 3x+ 0 =5x-12 3x=5x-12 3x-5x=5x-5x-12 subttract 5x from both sides -2x=0-12 -2x=-12 (-2x)/-2=-12/-2 divide both sides by -2. 1x= 6 -12/-2=6 and of course the -2 and -2 cancel on left side leaving 1x. x=6

Thank you so much now I can do the next one! :) I REALLY appreciate it.
