Answer:
2^8 2x2x2x2x2x2x2x2=256
Step-by-step explanation:
C 4and 12 are the factors of 48
Let x be your first alloy
2/5x+7/10(30-x)=1/2(30)
4x+210-7x=150
3x=60
x=20
So, you need 20 lbs of the first alloy, and 10 parts of the second to make 30 lbs of half iron and half silver alloy!
2 to 6 is one because angles can have different types
