Marvin has piece of chain that is 3_5 12 feet long. he uses 2 1_3 feet of the chain for his art project. how much chain does marvin have left? a 1__1 12 feet , b 1__2 12 feet , c 2__1 12 feet , d 2__2 12 feet

The answer is A. 1 1/2

Step-by-step explanation:

You have 3 5/12  - 2 1/3

1/3 of 12 is 4.

So change 2 1/3 to 2 4/12

3 5/12 - 2 4/12 = 1 1/2

I hope this helps!

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
