HELP! can you check and help me with some of these?
1. y + 8 = -15

2.3x = 27

3. 5 + a = -19

4. x + 1/3 = 5/6
My answer: NEED HELP WITH THIS ONE

5. -54 = -6y

6. a/3 = -11

7.19.5 = -39.5 + f

8.p - 1/3 = 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

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?

• Math - ,

No.
x = 5/6 - 2/6
x = ?

Do 11 and 12 the same way I showed you on the other problems.

• Math - ,

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?

• Math - ,

Yes. 4 is 3/6 = 1/2

11.

13.7 - x = -56.9
-x = -13.7 + (-56.9)
-x = -70.6
x = 70.6
