Metal alloy

What is the metal ratio in the alloy in the 50 tonnes of steel to 30 kg nickel?

Correct answer:

x =  0.06 %
y =  99.94 %
p =  0.0006004

Step-by-step explanation:


x = 100-y
x = 30/(50·1000)·100
p = 30/(50·1000-30)

x+y = 100
x = 0.06
p = 0.0006

Pivot: Row 1 ↔ Row 3
p = 0.001
x = 0.06
x+y = 100

Row 3 - Row 2 → Row 3
p = 0.001
x = 0.06
y = 99.94


y = 99.94/1 = 99.94
x = 0.06/1 = 0.06
p = 0.00060036/1 = 0.00060036

p = 3/4997 ≈ 0.0006
x = 3/50 = 0.06
y = 4997/50 = 99.94

Our linear equations calculator calculates it.
p=m(Fe)m(Ni)=5010003030=49973=0.0006004
