help with math?

Question

8(k+3)=12k-4

-3(5-9v)=25+7v

6x+4=5(3x+8)

5-11t=7(5-2t)

2(4a-12)+3a=6a+1

9(2+w)-4w=3w-10

10u+7=8(2u-4)-9

3(4d+1)-9d=6(2-d)

6(1+3m)negative8(negative2m+5)-4

-14+3(x+10)=7(2x+4)+x

6p-(5p+5)=negative8-2(p+12)

Answer 1

Hi,

I'll help with the first one, the rest are similar so this should help:

8(k+3)=12k-4

8*k +8*3 = 12k - 4

8k + 24 = 12k - 4

8k + 28 = 12k

28 = 4k

k = 28/4 =7

Good Luck!
Matt

P.S. I think it's ironic that someone who misspells 2/3 of the words in her post is calling someone else retarded. Seriously, is her time that valuable that she needs to abbreviate the word 'your'?

Answer 2

it's easy to get answer here.. but if you don't know how to do it, how are you going to do it on test? Test is usually worth more than the homework...

I will do a couple you do the rest
1) 8(K+3)=12k-4
8k+8*3 = 12k -4
8k +24 = 12k -4
8k -12k = -4 -24
-4k = -28
-k =-7
k=7


last quest
6p-(5p+5) = -8 -2(p+12)
6p-5p-5=-8-2*p-2*12
p-5= -8-2p-24
p+2p=-8-24+5
3p=-27
p=-9

Answer 3

will show you how to do one
...but not do your homework for you
cause then I will still know how to do it
....and you still wont

8(k+3) = 12k - 4 first simplify
8k + 24 = 12k -4 subtract 8k from both sides
8k-8k+24=12k-8k-4
24=4k-4 add 4 to both sides
24+4 = 4k-4+4
28=4k divide both sides by 4
7=k

Answer 4

What is this? I think you need to ask your teacher for extra help instead of having everyone else do your homework for you. Did you list out your entire assignment? Geez.

Answer 5

None of these are difficult. I think you're just trying to get someone to do your homework.

we'd help you if you post one or two problems
