Answer:
The Amin's score in math was 46.
Step-by-step explanation:
The question is:
The average math score for Amin, azman and aziz is 73. Azman marks 35 more than Amin while aziz is twice that of Amun. What is Amin's sign?
Solution:
Let us denote that:
<em>x</em> = Amin's score in math
<em>y</em> = Azman's score in math
<em>z</em> = Aziz's score in math.
The average of <em>x</em>, <em>y</em> and <em>z</em> is, 73.
That is:
![\frac{x+y+z}{3}=73\\\\\Rightarrow x+y+z = 219](https://tex.z-dn.net/?f=%5Cfrac%7Bx%2By%2Bz%7D%7B3%7D%3D73%5C%5C%5C%5C%5CRightarrow%20x%2By%2Bz%20%3D%20219)
Now it is provided that:
![y=x+35...(i)\\z=2x...(ii)](https://tex.z-dn.net/?f=y%3Dx%2B35...%28i%29%5C%5Cz%3D2x...%28ii%29)
Use the equations (i) and (ii) to determine the value of <em>x</em> as follows:
![x+y+z=219\\\\x+x+35+2x=219\\\\4x=184\\\\x=46](https://tex.z-dn.net/?f=x%2By%2Bz%3D219%5C%5C%5C%5Cx%2Bx%2B35%2B2x%3D219%5C%5C%5C%5C4x%3D184%5C%5C%5C%5Cx%3D46)
Thus, the Amin's score in math was 46.
Answer:
Once upon a time i was on brainly. I was asked to make a story and solve 15 divided by 1/9 so thats what this is :D Obviously I would do better stories on topics not math related but I thought it would do. I Used 15x1/9 to solve the equation and my helpful calculator UvU Thats when I got the ugly number of 1.66666667 as my answer I was annoyed but it would have to do. I finished typing these last words and submitted Hoping that i would get brainliest and give it away UvU
