I need to check my homework so can you just give me answers to these problems?
1. b/3 + 8 = -7
2 m - 3m + 3= 11
3. -3 (k-4) = -6
4. .5k - 3.4 = 0.1
5. .7x + 6 - .3 = 6.8
6. 2/3x - 5 = 17
7. 3/5y = 1/5 = 2
8. 4 (y-9)= 3 ( 2y - 8)
9 x + 7x + 15x = 29x + 18
10. 7x + 9 = 4x

Here you go:
1. b = - 45
2. m = - 4
3. k = 6
4. k = 0.7
5. x = 1.1/0.7
6. x = 33
7. You made a typo right there.
8. y = - 6
9. x = - 3
10. x = - 3
Hopefully I got those right, and hopefully you get an A!
Don't listen to the other people on Y! A, they can get REALLY MEAN sometimes.

Here are the answers you were looking for when you posted to Yahoo! Homework Help looking for help...not ridicule.
1. b/3 + 8 = -7
b/3 = -15
b = -45
2 m - 3m + 3= 11
-m = -8
m = 8
3. -3 (k-4) = -6
-3k +12 = -6
-3k = -18
k = 6
4. .5k - 3.4 = 0.1
.5 k = 3.3
k = 6.6
5. .7x + 6 - .3 = 6.8
.7x = 1.1
x = 1.57
6. 2/3x - 5 = 17
2/3x = 22
2 = 66x
1/33 = x
7. 3/5y = 1/5 = 2
Typo...
8. 4 (y-9)= 3 ( 2y - 8)
4y-36 = 6y-24
-2y = 8
y = -4
9 x + 7x + 15x = 29x + 18
23x= 29x +18
-18 = 6x
-3 = x
10. 7x + 9 = 4x
9 = -3x
-3 = x

1. b/3+8=-7
b/3+8-8=-7-8
b/3=-15
multiply by 3
b=-45
2.m-3m+3=11
-2m+3=11
-2m+3-3=11-3
-2m=8
-2m/2=8/-2
m=-4
3. -3(k-4)=-6
-3k+12=-6
-3k+12-12=-6-12
-3k=-18
-3k/-3=-18/-3
k=6
4..5k-3.4=0.1
.5k-3.4+3.4=0.1+3.4
.5k=3.5
multiply by 2 both sides
1/2 k(2)=3.5(2)
k=7
5 .7x+6-.3=6.8
.7x+5.7=6.8
.7x+5.7-5.7=6.8-5.7
.7x=1.1
multiply both sides by 10/7
x=1.1=11/10 *10/7=11/7
x=11/7
6. 2/3x-5=17
2/3x-5+5=17+5
2/3x=22
2/3x(3/2)=22*3/2=66/2
x=33
7. 3/5y +1/5=2
Multiply all by 5
3y+1=10
3y+1-1=10-1
3y=9
y=3
8. 4(y-9)=3(2y-8)
4y-36=6y-24
4y-4y-36=6y-4y-24
-36=2y-24
-36+24=2y-24+24
-12=2y
-6=y
9. x+7x+15x=29x+18
23x =29x+18
23x-29x=29x-29x+18
-6x=18
-6x/-6=18/-6
x=-3
10. 7x+9=4x
7x+9-9=4x-9
7x=4x-9
7x-4x=4x-4x-9
3x=-9
x=-3
