Math question, can someone help please?

Question

Please help, i don't understand.

1) 5/6 / 4/5 + 5/6 x 5/7

~5 over 6 divide 4 over 5 plus 5 over 6 multiply 5 over 7~ #1-detail

2) 6-2x=5x-9x+10

Answer 1

2) take the similar functions (5x,9x,2x) and deal with them first so 5x-9x= -4x then take that -4x and add it over to -2x making it positive 2x. then subtract the 6 over to the 10 on the right side of the equation to get 2x=4 which simplifies to x=2.

Answer 2

1.) 5/6 is a fraction, as is 4/5. You need to do divide two fractions. To do this you multiply the reciprocal of the other number.

Example

5/6 / 4/5 = 5/6 * 5/4 = 25/24

To do 5/6 * 5/4 you just take 5 * 5 and put that over 6 * 4.

2.) This is a more difficult algebra problem. To do these problems you want to solve to get X on one side and by itself. To do this I would put all like terms on one side.

Example:

6-2x=5x-9x+10

= -2x = 5x - 9x + 4  >>> I subtracted 6 from both sides

= -4 = -9x + 5x + 2x  >>> I subtracted 4 from both sides and added 2x

Now add like terms

-4 = -9x + 5x + 2x

= -4 = -2x

And Solve from there.

Good luck!

Answer 3

1.)try same change flip for the first problem then multiply so it would be

(5/6) times (4/5) plus (5/6) times (5/7) which gives you

(24/25)plus (42/25) which equals

66/25

the problem takes a bunch of basic fraction principles and runs them togeather if you just divide the problem up and work on it piece by piece it will become alot easier

2.)6-2x=5x-9x+10

  -6                 -6

     -2x=5x-9x+4

    -2x=-4x+4

   +4x  +4x

     2x=4

divide both sides by two and you get the answer x=2
