2x+x=36
Kim's Sister age

2x+x=36 Add "x and 2x"
3x=36 Divide both sides by 3
÷3 ÷3
x=12
Kim's sister is 12 years old
Soo....
Multiply that by two to get Kim's age

12•2=24 Kim is 24 years old.

Why did the math teacher open a window company?

umka2103 [35]

A math teacher opened a window company because he loves seeing shapes or geometrical polygons such as rectagles, squares or quadrilaterals in general as well as triangles in his works. Of course, the math teacher is already familiar with these shapes and how to calculate the angles in between.
