pls answer fast

Answer 1

Answer:

Given that :

1) 4.5 grams of alloy gives 3.5 grams of copper.

Then,

2) Let 18.9 grams of alloy gives y grams of copper.

Let, required weight beY.

Y = (18.9×3.5)÷(4.5)

Y = 14.7 grams....

So,

Required weight of copper is 14.7 grams.

Step-by-step explanation:

I hope it is helpful for you.

Answer 2

Let the amount of zinc and copper in the alloy be 3x and 4x.
Total weight of the alloy=35g
According to the question,
3x+4x=35
7x=35
x=35/7=5
Weight of copper in the alloy of weight 35g is 4x=4*5=20g
