The alloy consists of 19 parts aluminum 2 parts magnesium (by weight).

The alloy consists of 19 parts aluminum 2 parts magnesium (by weight). What is the mass of an alloy if it contains 34 kg less magnesium than aluminum?

To complete this task, you need to create an equation. Let one part be equal to x kg, then in the aluminum alloy 19x, and magnesium 2x. Knowing that magnesium in the alloy is 34 kilograms less than aluminum, let’s make an equation.

19x – 2x = 34;

17x = 34;

x = 34/17;

x = 2.

Let’s calculate what the mass of the alloy is, knowing that one part weighs 2 kilograms.

19x + 2x = 21x = 21 * 2 = 42 kilograms.

Answer: 42 kilograms.
