2 answers:
Answer:
Let X be the amount of each metal needed to make 35 Kg of this alloy.
We know that an alloy is composed of nickel, zinc and copper in a proportion
4:1:2. Therefore, we have:



Kg
Therefore, there are
kg of nickel,
kg of zinc, and
kg of copper needed to make 35 kg of this alloy
Answer:
Step-by-step explanation:
The ration of weight of nickel, zinc, and copper in an alloy is 4:1:2
The weight of alloy can be written as
4x + x + 2x = 35 Kg
7 x = 35 Kg
X = 35 Kg/7
X = 5kg
The weight of nickel the alloy = 4 x 5 = 20 Kg
The weight of zinc in the alloy= 1 x 5 = 5kg
The weight of copper in the alloy = 2 x 5 = 10 kg

Answer:
12a^3-6a^2+2a+9
Step-by-step explanation:
12a^3-6a^2-2a+7+4a+2
12a^3-6a^2+2a+7+2
12a^3-6a^2+2a+9
Let unknown number be x.
Given,
7x - 8 = 3x + 4
4x = 12
x = 3
Hence, the number is 3.
