The value of cement mixer after t year is
Given to us
The value of cement mixer when bought, = $ 54,205
the value of cement mixer after 1 year, = $ 47,158. 35
the value of cement mixer after 2 year,= $ 41,027. 76
To find out depreciation we can use the formula for depreciation,
By putting the value, in the formula we get,
Therefore, putting the value of and
in depreciation formula for
years we get,
Hence, the value of cement mixer after t year is .

Answer:
<h2>If we placed the number 10 in the box, we obtain a system of equations with infinitely many solutions.</h2>Step-by-step explanation:
The given system is
<em>It's important to know that a system with infinitely many solutions, it's a system that has the same equation</em>, that is, both equation represent the same line, or as some textbooks say, one line is on the other one, so they have inifinitely common solutions.
Having said that, the first thing we should do here is reorder the system
This way, you can compare better both equations. If you look closer, observe that the second equation is double, that is, it can be obtained by multiplying a factor of 2 to the first one, that is
So, by multiplying such factor, we obtaine the second equation. Observe that must be equal to 10, that way the system would have infinitely solutions.
Therefore, the answer is 10.
