Can you please correct/check my MATH homework, Thanks!?

Question

PLEASE CORRECT THEM IF THEY'RE WRONG, THANKS!

1. 14 + t/11= 17
t = -33
2. 3/8m + 9= 18
m = 4
3. 1/9e - 8= 30
e = -8
4. 105/5= 3(4 - 2b)
18= b
5. 13 + f - 8f= 25 x 5
f= 13
6. 3x= -x + 2
8= -x
7. 3x + 4= 2x - 6
-9 = x
8. -7r - 8= -5r = 3
r = -13
9. 34= 3(t + 6) -8
16 = t
10. 15 - 6(x + 2) = 1
x = 6
11. 26= -5(4 + 8y) -6
44 = y
12. 26= -5(4 + 8y) -6
-56= y
13. 0.3(p + 4)= 2.7p
22 = p
14. 4q +19= 5/6q
24= q
15. 2/3a = -15 - a
a = 45

NOT all of the are RIGHT, so please just make sure that they are all right PLEASE, thanks!

Answer 1

1. close, but wrong.
2. wrong.
3. wrong.
4. wrong.
5. wrong.
6. wrong.
7. close, but wrong.

Sorry, I'd be willing to help you with some of them if you showed some work, but I'm thinking maybe you're just guessing on these.

Here's the first one:

14 + t/11 -14 = 17 - 14
t/11 = 3
t = 33

Here's the last one:
2/3a = -15 - a
Multiply both sides by 3
2a = 3(-15 - a) = -45 - 3a
Add 3a to both sides
2a + 3a = 5a = -45 - 3a + 3a = -45
Divide both sides by 5
a = -9

You do the rest.

Answer 2

most of your answers are wrong.

for question 1,

14+t/11=17
154/11+t/11=17
154+t=187
t=187-154
t=33.

2)3/8m+9=18
3/8m+72m/8m=18
3+72m=144m
3=144m-72m
3=72m
3/72=m

3)1/9e-8=30
1/9e-72e/9e=30
1-72e=270e
1=342e
1/342=e

4)105/5=3(4-2b)
105/5=12-6b
105/5-12=-6b
9=-6b
-9/6=b
-3/2=b

you do the rest.just follow the step i've shown.....

Answer 3

What grade is this? This is simple! That actually would take a while but use a calculator, I think they are all right if you really know fractions, Discuribtive Property, and simple Elementary school math.

Answer 4

1250-70t=distance maggie has left to school 800-40t=distance ming has left to school 1250-70t=800-40t 450=30t t=15 at 15 minutes maggie will catch ming maggie is behing ming when t<15 minutes

Answer 5

NO: I'll not do your homework. I believe that your first answer was not negative, on #2: 3/8m=9
3m=72
m=24
.... and now it is your turn. THINK and TRY Damnit. (If you ARE thinking and trying and I can help...contact me.)

Answer 6

I just checked a random sampling: You did not have one correct answer. It will be easier to address the problem if you show your work.

Answer 7

man i wish i had this type of math but they all look right
