X = -15 because first u move the ax’s to one side so it would be 3x-5x=25+5 then u calculate each side 3x-5x= -2x and 25+5=30 so -2x=30 and then u divide both sides by -2 and -2/-2 cancels out and 30/-2 equals -15 (I hope his helps) :))

An alloy consists of nickel, zinc, and copper in the ratio 2:7:9.
Alexus [3.1K]

Answer:

0.4kg, 1.4kg and 1.8kg

Step-by-step explanation:

Given parameters:

         Mass of alloy = 3.6kg

         Ratio of elements in the alloy = 2:7:9

Unknown:

Mass of each element in the alloy = ?

Solution:

To find the mass of each element in the alloy, first find the sum of the ratio;

              2+7+9 = 18

Mass of nickel  = \frac{2}{18} x 3.6 = 0.4kg

Mass of zinc = \frac{7}{18} x 3.6 = 1.4kg

Mass of copper = \frac{9}{18} x 3.6 = 1.8kg

The mass of each metal is 0.4kg, 1.4kg and 1.8kg
