Answer:

Step-by-step explanation:

first lets find the total # of portions:

3+4+13=16+4=20

To make 4kg of this alloy you have to use:

nickel: (4/20)*3=12/20=6/10=0.6 kg

zinc: (4/20)*4=16/20=8/10=0.8 kg

copper: (4/20)*13=52/20=26/10=2.6 kg

If you multiply 35 times 50 you will get the total area after land. That is 1750. 1750-1600 is 150

1/3y+1/4=5/12 i need 20 character
lys-0071 [83]
Y/3 + 1/4 = 5/12
4y/12 + 3/12 = 5/12
           4y/12 = 2/12
                4y = 2
                /4     /4
                  y = 1/2

Therefore y = 1/2
