Question

(k-10) ÷ (2k-20)

Answer 1

This is easier to see in a fraction:
\[\frac{k-10}{2k-20}\]If you factored a 2 out of the bottom, what would it become?

Answer 2

Another way is to substitute (k-10) for x.

Answer 3

-1/2?

Answer 4

Not quite
\[\frac{k-10}{2(k-10)}\] Then they cancel so:
\[\frac{1}{2}\]

Answer 5

well isn't it that the 2k is negative and the 20 is positive?

Answer 6

oh wait sorry the problem i wrote was different from the one in my book

Answer 7

the -10 is negative. OH! that would make a differenc.

Answer 8

you're correct though, thank you so much!

Answer 9

Well lets see the one in your book! If you still need help with it.

Answer 10

problem was originally k-10/20k -2k. being an 8th grader in algebra I is hard :/

Answer 11

We were all there once.
Hmmm.... that one has more to it.
\[\frac{k-10}{20k -2k}\]

Answer 12

If no mistyping this time... it is just some subtraction.
\[\frac{k-10}{18k}\]

Answer 13

I am in Algebra I in school but doing harder math at home.

Answer 14

About precalc to easy calc level

Answer 15

We all do different subjects at different speeds. There are some people that go through all this reall fast, and other that need more time. That is one problem with school, they expect everybody to learn everything at the same speed. I was good in math and decent in history, but had problems elsewhere.

Answer 16

I have problems in History :( I am horrible at history am afraid of test coming up :( OH NO FORGOT TO STUDY

Answer 17

Perhaps you need less time in the extra math and more in the history! LOL. Well, that one depends a lot on the teacher and how they test. I hate it when they want names and dates. I like it when they just want the important stuff, like the whys and the whats. But when and who kill me.

Answer 18

k-10/2(k-10),cancel out the k-10=1/2

Answer 19

@dwelsher It was the wrong problem, by we got the process worked out and he got it already. Hehe
