multiply or divide as indicated and reduce to lowest terms where appropriate: 2x-4/5x X 15x/x-2
@Mathematics

Answer 1

how the hell?!

Answer 2

I assume that is
\[\frac{2x-4}{5x}\frac{15x}{x-2} \]
right?

Answer 3

You can rewrite that like this...
\[\frac{2(x-2)}{5x}\frac{3(5x)}{x-2} \]
which would be six, no?

Answer 4

correct how did u write it like that? i cant write it like that in the question box

Answer 5

but i dont know how you are even re writing it

Answer 6

It's called LaTeX, don't worry about it. And just look at it, I dunno what else to tell you really. 2x-4 = 2(x-2), right?

Answer 7

yes

Answer 8

So, the (x-2)'s cancel, and the 5x's cancel, leaving you with 2*3 = 6.

Answer 9

ohhhhh okay thank you!

Answer 10

so what about -8 X n/-3msquared

Answer 11

you can cancel the negative signs.

Answer 12

this is such hard math

Answer 13

i dont know how to calculate algebraic functions

Answer 14

Such as?

Answer 15

i dont know to write it

Answer 16

(5/pqSQUARED) ( -3pCUBEDr/10q)

Answer 17

\[\frac{5}{pq^2}\frac{-3p^3r}{10q}\]
?

Answer 18

how do u do that?

Answer 19

You'll notice the "Equation" button just below the text box.

Answer 20

i see it but i havent figured out how to work it

Answer 21

It's a document typesetting language called LaTeX. If you can't work the buttons don't worry about it because what I just typed looks like this:
"\frac{5}{pq^2} \frac{-3p^3r}{10q} "

Answer 22

I understood what you meant well enough when you just typed it.

Answer 23

okie doke

Answer 24

And to answer your question, that would be
\[\frac{-15p^3r}{10pq^3} = \frac{-3p^2r}{2q^3}\]

Answer 25

can you explain how you got that?

Answer 26

I can tell you that when you multiply fractions, you multiply the numerators and denominators together, and that 15 and 10 share a common factor of 5 so that reduces to 3/2 when you cancel it, and p^3 / p = p^2, but besides that, I apologize, I do not know how to explain it further.

Answer 27

thanks i just not that good at math
