If i give my sister 5 dollars, then we will have the same amount of money. if instead she gives me 8 dollars, then i'll have twice as much money as she has. how much money does she
have?

The money my sister have is $34

Step-by-step explanation:

Given as :

The two statements are as

If I give my sister 5 dollars, then we will have the same amount of money  ...A

If instead she gives me 8 dollars, then I'll have twice as much money as she has.      B

Let the money I have = $x

And The money my sister have = $y

Now, From statement A

x - 5 = y + 5

or, x - y = 5 + 5

or, x - y = 10          1

Again, From statement B

2 ×(y - 8) =  (x + 8)

2 y - 16 = x + 8  

2 y - x = 24         2

Now, solving Eq 1 and 2

Put the value of x from eq 1 into eq 2

2 y - (y + 10) = 24

Or, 2 y - y = 24 + 10

Or, y = 34

So, The money my sister have = y = $34

Put the value of y into eq 1

so, x - 34 = 10  

I.e x = 10 + 34

∴ x = 44

So, The money I have = x = $44

Hence, The money my sister have is $34 Answer

i got the answer by:

24+4=28

28/4=7  

8

step-by-step explanation:

to find the amount of gift bags to use all the supplies, find the gcf or greatest common factor. this is the largest number which multiplies evenly into each term.

48 has factors: 1, 2, 3, 4, 6, 8, 12. 16, 24, 48

80 has factors: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

64 has factors: 1, 2, 4, 8, 8, 16, 32, 64

the highest number factor they all share in common is 8. this means there will be 8 bags with 6 pencils, 10 markers, and 8 stickers in each bag.
