math problem people i need help somebody help me please i begging my last two and i keep getting the wrong?

Question

i would ask people in here and nobody can give me the right answers, so the computer keep giving me other problems until i get the one similar to the one i had wrong correct..helpppppppppppppppppp it only 2

type both problems in inequality form. solve the inequality for both..
5x+3 is the numerator and 6 is the deminator minus 2x-3 in the numerator and its over 5 in the denominator > and or = to 3.

next problem is..
2/5 (x+6)>1/4 ( 4x+2)

Answer 1

[(5x+3)/6] - [(2x-3)/5] >= 3

first get rid of the denominator, multiply everything by 30:

5(5x+3) - 6(2x-3) > = 3*30

25x + 15 - 12x + 18 >= 90

25x - 12x >= 90 -15 - 18 (oops i forgot that!)

13 x >= 57

x > = 57/13 (they were right on this one! :D)

2nd one...

2/5 (x+6) > 1/4 (4x + 2)

get rid of the denominator, multiply both sides by 20

8 (x+6) > 5(4x + 2)

8x + 48 > 20x + 10

38 > 12 x

38/12 > x

19/6 > x

Answer 2

Let me say first, if you don't understand your homework, and you are copying answers left and right from the net, you will (a) never learn the stuff, and (b) thus fail the class.

Get some understanding girl...math isn't complicated, but it takes quality practice.

(5x+3)/6 - (2x-3)/5 >= 3

30 is the common denominator.

Multiply the first term by 5/5, the second term by 6/6, and the right term by 30/30.

(25x+15)/30 - (12x-18)/30 >= 90/30

Since all denominators are common, multiply all terms by 30, basically killing the fractions.

(25x+15) - (12x-18) >= 90

Simplify.

13x + 33 >= 90

13x >= 57

x >= 57/13

I won't do the 2nd one. If you understand one, you should get the second.

Answer 3

First, I would multiply out all the fractions:

2/5*x + 12/5 > x + 1/2

Then solve by moving all the x's to one side and regular numbers to the other

19/10 > 3/5*x

Then solve for x

19/6 > x

You might want to double check the math, I just did all that in my head.

Answer 4

okay...dont quote me on this one..its been a while since ive done this stuff (and by that i mean september 2004 when i did grade 20 math) but i've gotten the first one down to
x > or = to 57/13
but thats as much as i remember...hope that helps you out a little bit and im still working on the second one

and for the second one i got 21/24 < x
but im not too sure about that one

Answer 5

2/5 (x+6)> 1/4(4x+2)

answer: x < -1

i think this is right
did this stuff a couple years ago
i dont really bother checking it

Answer 6

sorry 1979 ... the confusion is in the definition

Redefine the problem -
