Question 1181290
<font face="Times New Roman" size="+2">


Let *[tex \Large x] represent the number of 2-point questions, *[tex \Large y] represent the number of 5-point questions, and *[tex \Large z] represent the number of 10-point questions.


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ x\ +\ y\ +\ z\ =\ 50]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ x\ =\ 3z]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ y\ =\ 2x\ -\ 10]


Solve the 3X3 system for *[tex \Large x], *[tex \Large y], and *[tex \Large z]


Then calculate


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 2x\ +\ 5y\ +\ 10z]

My calculator said it, I believe it, that settles it
