Answer:
Bag 1: 20
Bag 2: 40
Step-by-step explanation:
Let x be the amount taken out of bag 2
Then the amount left in each bag can be written as:
Bag 1: 50-3x
Bag 2: 50-x
Since we know that half of bag 2 is bag 1, that gives us:
50-3x = 1/2(50-x)
-> 50-3x = 25-x/2
Now lets isolate x and solve:
25 = 5x/2
-> 50 = 5x
-> x = 10
So plug x bag in for the original equations:
Bag 1: 50-3x = 50-3(10) = 20
Bag 2: 50-x = 50-10 = 40

Answer:
ans = 4
Step-by-step explanation:
he has 2 1\2 and 4 1\4
to find the ans, we must firstly find out his total amount of fabric, so we add the available fabric
first we add whole numbers
2 + 4 = 6
then we add fractions
1 1
--- + ---
2 4
2 + 1 3
------------- = ---
4 4
after we add the whole no and fraction
6 + 3\4 = 6 3\4
note 10 1\2 is greater than 6 3\4
so to find the part left, we
have
10 1\2 - 6 3\4
as our answer
