My answer: 9
3. 5 + a = 19
My answer:24
4. x + 1/3 = 5/6
My answer: NEED HELP WITH THIS ONE
5. 54 = 6y
My answer: 9
6. a/3 = 11
My answer: 33
7.19.5 = 39.5 + f
My answer: 20
8.p  1/3 = 2/7
My answer: 2/7
9. x/11 = 6.1
My answer: I NEED HELP WITH THIS ONE
10. 9 = t/2
My answer: I NEED HELP WITH THIS ONE
11. 13.7  x = 56.9
My answer: I NEED HELP WITH THIS ONE
12. 43 = 21  m
My answer: I NEED HELP WITH THIS ONE

Please rethink 7 and 8. The other answers are correct.
4.
x + 1/3 = 5/6
x = 5/6  1/3
x = 5/6  2/6
x = ?
9.
x/11 = 6.1
x = 6.1 * 11
x = 67.1
10.
9 = t/2
18 = t
18 = t
Please try 11 and 12 yourself. 
so does #4 equal 5/6? That's what i got.
I actually don't get number 11. or 12., how are you suppose to set it up? 
No.
x = 5/6  2/6
x = ?
Do 11 and 12 the same way I showed you on the other problems. 
but on 11 and 12 you have to add the opposite to m. i don't get how to do that
is #4 one half? 
Yes. 4 is 3/6 = 1/2
11.
13.7  x = 56.9
x = 13.7 + (56.9)
x = 70.6
x = 70.6 
i figured the rest out! thank you so much! I love jiskha!
P.S Ms.Sue, i really thank you, you volunteer and help so many students, including me. Sorry for asking so much! i just got in high school, and really need the help daily. Are you the owner of Jiskha? :) thanks, love bryce
