7th grade math!!?

Question

okay...im still having a lot of trouble on this my mom wont help me so i cant really get the rest of these answers......
[[Simplify]]

1.) -7(w - 4) + 3w - 27

2.) 1 - s + 2 +2s - 3s +1

3.) -11f + 6 - f + 4 + 13f -9

4.)1 - g + 5 - 2g + 3(g - 2)

5.)-12 + 7(d - 1) + 14 - d

2.)27.) -11f +6-f + 4 + 13f - 9

Answer 1

I wont give you all the answers. I will tell you this. For example: the last one. Solve the ones with the "f" first. So, 11f+13f-f= 23f. Then solve the ones without the f. 6+4-9= 1. Your answer should be 23f + 1.

Answer 2

I'll do the first 2 step by step... but u should learn how to do them on ur own or ask ur teacher for help if ur really struggling.. okay..

1. -7(w-4)+3w-27

Distribute the -7 into (w-4)= -7w+28+3w-27
Comine the -7w and the +3w = -4w+28-27
Comine the + 28 and the -27= -4w+1
The answer: -4w+1

2. 1 - s+ 2 + 2s - 3s + 1

Combine the first 2 s's = 1 + s + 2 - 3s + 1
Combine the other 2 s's = 1 + -2s + 2 + 1
Combine the 1, the +2, and the +1= 4+-2s
Simplify: 4 - 2s
Put your variable in front (thought not neccessary)= -2s+4
Answer: -2s + 4

Hope this helps.. I know math can be challenging. And use those steps and apply them to those other problems. And like I said, still struggling; ask your teacher or ask ur mom for a tutor.. Good luck, hun.

Answer 3

Hmm, I have a feeling that your mom thinks you should be doing your homework yourself. Which part is confusing for you?
tips: Do everything in paretheses first. Do anything with multiplication and division. Next add and subract like terms.
Example:
-7(w-4)+3w-27
Mutiply terms in () by -7
-7w +28 ( remember two negatives make a positive when Multiplying)
so now the problem is :
-7w + 28 +3w-27
Now add and subtract similar terms:
-7w+3w +28-27
Ta da, the final answer is ....
-4w+1
Problem 2 Rewrite all the whole numbers grouped together and all the "s" terms grouped together. Add and subtract.
Problem 3 is also just a matter of grouping whole numbers together then group "f" factors. Add and subtract.
Problem 4
Do the 3(g-2) first:
3g-6
Then group whole numbers and g factors. Add and subtract.
Problem 5
Do 7(d-1) first
7d-7
Then group whole numbers and d factors. Add and subtract.
The last problem is confusing to me. What is the 7th problem? If the problem begins with -11f then you can simply group the whole numbers together and the f factors togetehr. Add and subtract.

I hope this helps you. We do want to help, but we also know how important it is for you to learn how to do this yourself. I hope I gave enough information to get you back on track. You may want to go to your teacher before school, during a break or after a school for a little extra help. Some schools even have a tutoring program, especially for math.
I am also including one link that has free math help in a variety of math topics. That way you don't have to wait for someone to help you at Yahoo answers. Good luck.

Answer 4

-7w +28 + 3w - 27
therefore...-4w +1
do u get it...cuz i wont do it all for you....cuz i want u to pay attention in class and try
what ur doing is adding up like terms
numbers go together
variables go together
soo
2) 1- s +2 +2s -3s +1 can be re written as 2s -s -3s +1 +2 +1
right...so number 2 should be 4 - 2s...obviously all these can be moved around if it helps...because it doesnt change the values or signs(neg/pos)
3)can be re written as -11f +13f -f +6 +4 -9
so its 1+f
u should be able to do the rest :)

Answer 5

multiply out any brackets and gather together the letters and the pure numbers

-7(w - 4) + 3w -27
=-7w + 28 + 3w -27
= 28 - 27 -7w + 3w
= 1 - 4w

1 - s + 2 +2s - 3s +1
= 1 + 2 + 1 -s + 2s - 3s
= 4 - 2s

try the rest yourself

Answer 6

wow, easyyy
what school do u go to?
Well i think i know the answers, i'm in 7th too
1.)-7w+28+3w-27= -4w+1
2.) -2s+4
3.) f+1
4.) 1-g+5-2g + 3g-6 = 0
5.)-12+7d-7 +14 - d = -5+6d
6.) f +1 (by the way thats the same problem as number 3)
I hope this helped, it was way simple. If you want me to explain you can just post another question, =P good luck

Answer 7

1.) Distribute the -7 to (w-4)
-7(w) -7(-4)
The negatives turn into a positive making the equation

-7w+28+3w-27
Combine like terms

-4w+1

2.)Combine like terms
-s+2s-3s+4
Combine like terms again
-2s+4

3.)Combine like terms
-11f-f+13f+1
Agian
f+1

4.)Distribute 3(g-2)
1-g+5-2g+3g-2
Combine like terms
-g-2g+3g-1
Combine like terms
-3g+3g-1
They cancel out
-1

5.)Distribute
-12+7d-7+14-d
Combine like terms
7d-d-5
Combine like terms
6d-5

2.)27.)Combine like terms
-11f-f+13f+1
Combine again
f+1

Answer 8

1) -7(w-4)+3w-27
-7w+28 +3w-27
-4w+1

This is the example on number one. For the others, combine like terms, so like on number 2, combine all the numbers with S's, and then combine just the plain numbers.

Answer 9

I will only do one..
-7(w - 4) + 3w - 27
-7w+28+3w-27
-7w+3w+28-27
-4w+1
First multiply, then combine like terms, oh don't forget to put the # with the variable first..like shown..

Answer 10

it is not obtrusive to evaluate 3/8 and 2/3, yet seem at it this way: could you quite slice a pie into 3 products and take 2 (2/3 of a pie), or slice it into 8 products and take 3 (3/8 of a pie)? in case you like pie, you will probable make the 1st decision, and that's using fact 2/3 is larger than 3/8. hence 3/8 < 2/3. the mathematics thank you to do it is to multiply the left facets by way of 3/3 and the superb area by way of 8/8 (the two are fancy methods of writing a million). then you particularly've 9/24 on the left area and sixteen/24 on the superb area. Now the huge type on the backside is the same and that could be a lot much less confusing to evaluate; of course 9/24 < sixteen/24. In different words, you're cutting the pie into 24 products; 3/8 of the pie is comparable to taking 9 products, and 2/3 of the pie is comparable to taking sixteen products.
