Answer 1
Answer: Alright, take it step by step...in month one, they had 5 members.
if the number doubles each month, then the second month they will have a total of ten members, right? in the third they will have twice the number before, or 2 times 10, 20. if you double 20, you have the number of people in the fourth month, giving you a grand total of 40.
Answer 2
Answer: Since you know that the number of club members doubled every month , you would multiply how much members in one month by 2 
1 month= 5  members multiply by 2
2 month= 10 members multiply by 2
3 month = 20 members multiply by 2 
4 month= 40 members

So, for each moth you multiply it by 2.
After 4 months there will be 40 members

a 290 inch pipe is cut into two pieces one piece is four times the length of the other find the links of the two pieces

Answers

290=x+4x
290=5x
x=290/5
x=58 inch (the shortest piece)

290-58=232 inch (the longest piece)
I would set an equation up like this, where two pieces, one being 4 times as long as the other, are 290 inches together.

4x + x = 290

Now, simplify and solve:

5x = 290

x = 58

Now that we have x, we know the length of the smaller piece.  The other piece, however, is 4x.

4x = 4(58) = 232

The lengths of the pieces are 58 and 232.

Is this right and what's the answer for number 3?

Answers

Answer: Hello!

the problems are wrong:

in the first problem, you have 38 rocks, and you can separate them into groups of 10 or in single rocks.

You have 4 options to do it:

0 groups of 10, and 38 single rocks.

1 group of ten and (38 - 19) = 28 single rocks

(this is 10 rocks in the group of then + 28 single rocks = 38 total rocks)

2 groups of ten and (38 - 2*10) =  18 single rocks

3 groups of ten and (38 - 3*10) = 8 single rocks

and you can't form more groups of tens because you only have 8 single rocks left at this point.

in the second problem, the case is the same, now you have 30 pieces of felt and you can divide them into groups of 10 or in single pieces.

then the possible options are:

0 groups of ten and 30 single pieces

1 group of ten and (30 - 10) = 20 single pieces

2 groups of ten and (30 - 2*10) = 10 single pieces

3 groups of ten and (30 - 3*10) = 0 single pieces

in the third problem you need to write, similarly as i did, why you organized the rocks or the pieces as you did.
That looks great! But say you chose number 2. You could say you organized it by multiplying single packs by the pieces of packs.
