For anyone that cares to answer for the last time !!!?

Question

Ok i previously posted a question for the following equation :

4/3 - 1/5t = 3/4

Anyone please tell me what part of this did i go wrong :

4/3+4/3 - 1/5t =3/4 +4/3
1/5t = 3/4 + 4/3
1/5t= 9/12 + 16/12
5/1x 1/5t = 25/12 x 5/1
t= 125/2

I am doing the opposite of 4/3 - 1/5t !!!

Answer 1

Your first step. You added 4/3 to both sides. You needed to subtract.

4/3-4/3 -1/5t = 3/4-4/3
-1/5t = -7/12
-5* -1/5t = -5* -7/12
t = 35/12

Answer 2

Hi:

Has far as I can tell you didn't do signs right and you didn't Simply your improper faction and prove your answer right

So:


4/3 - 1/5t = 3/4

- 4/3+ 4/3 - 1/5t = 3/4 - 4/3

-1/5t = 3/4 - 4/3

-1/5t= 9/12-16/12

-1/5t = -7/12

-1/5t = -7 / 12

-5/1 *(-1/5)t = -5*(-7/12)

t= 35/12

t= 2 11/12


Proof:
So
4/3 - 1/5t = 3/4

4/3- 1/5*(35/12) = 3/4

4/3- 35/60 = 3/4

80/60- 35/60 = 3/4

45/60 = 3/4

3/4= 3/4

So : 35/12 or 2 11/12 is the Correct answer

P.S: Watch your signs they will mess you up every time

Answer 3

the problem is in first part
you have to eliminate the constant in the side of the equation where the variable is
so you have to add both side of the eq to its additive inverse
and the additive inverse of 4/3 is -4/3

4/3+4/3 - 1/5t =3/4 +4/3
will be 4/3 - 4/3 - 1/5t =3/4 -4/3
1/5t = 3/4 - 4/3
1/5t= 9/12 - 16/12
1/5t= -7/12
5/1x 1/5t =-7/12 x 5/1
t= 35/ 12

checking:
4/3 - 1/5t = 3/4
but t= 35/ 12
4/3 - 1/5(35/ 12) = 3/4
4/3 - 7/12 = 3/4
16/12 - 7/12 = 3/4
9/12 = 3/4
3/4 = 3/4

Answer 4

The very first line is wrong. If you want to eliminate 4/3 from the left side, which you have to, you should subtract 4/3 from both sides, not add it.

4/3 - 1/5t = 3/4
4/3 -4/3 -1/5t = 3/4 - 4/3
-1/5t = (9 - 16)/12 = - 7/12
-1/5t = -7/12
1/5t = 7/12

Now I have a question: is that 1/(5t) or (1/5)t?
if it is 1/(5t) then you get:
35t = 12 ------> t = 12/35

if it is (1/5)t then you get:
12t = 35 -------> t = 35/12

Answer 5

its 4/3-4/3-1/5t=3/4-4/3
-1/5t=3/4-4/3
1/5t=4/3-3/4
1/5t=16-9/12
t=7/12*5
t=35/12

when u substitute t in the equation. U WILL GET THE ANSWER 3/4

Answer 6

You left out the - sign from the 2nd step on.
JTRaceFan is right, too...
4/3 - 4/3 - 1/5t = 3/4 - 4/3
-1/5t = 3/4 - 4/3
-1/5t = 9/12 - 16/12
5/1x -1/5t = -7/12 x 5/1
-t = -35/12
t = 35/12

Answer 7

4/3 - 1/5t = 3/4
4/3 - 4/3 - 1/5t = 3/4 - 4/3
-1/5t = -7/12
t = 35/12

You're error is #1 adding instead of subtracting 4/3
#2 you didn't leave the - sign in front of 1/5 in your step 2.

Answer 8

first line : add 4/3 to both sides - looks alright

second line : line is erred..

you should have done:

first line: add (1/5t - 3/4) to both sides
u should get:
4/3 - 3/4 = 1/5t
16/12 - 9/12 = 1/5t
7/12 = 1/5 t
therefore multiplying both sides by 5
35/12 = t

Answer 9

I will suggest to get the demonate out by
60(4/3 - 1/5t) = (3/4)60 now u have

80 - 12t = 45

see it's easier to work with because 60 is the comman demonate for all.

subtract 80 to both sides
80 - 12t = 45
-80 -80

-12t = -35

divide by -12

-12t/-12 = -35/-12
t = 2.91 repeating
round to 3 or 2.9

Answer 10

4/3-1/5t=3/4
4/3-4/3-1/5t=3/4-4/3
-1/5t=-7/12
(-5)(-1/5t)=(-5)(-7/12)
t=35/12 or 2.91666~
