\huge \mathscr{\blue {\underline {\red{\underline{Answer :-}}}}}

\bf \frac{5}{2} x - 7 =  \frac{3}{4} x + 14

\bf \implies \:  \frac{5}{2} x -  \frac{3}{4} x = 14 + 7

\bf \implies \:  \frac{10x - 3x}{4}  = 14 + 7

\bf \implies \:  \frac{7}{4} x = 21

\bf \implies \: 7x = 21 \times 4

\bf \implies \: x =  \frac{21 \times 4}{7}

\bf \implies \: x = 3 \times 4

\bf \implies \: x = 12

ᴏᴘᴛɪᴏɴ (ᴅ) x = 12 ɪs ʏᴏᴜʀ ᴄᴏʀʀᴇᴄᴛ ᴀɴsᴡᴇʀ

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
