How do i solve for m
k=am+3mx

In the lab, I conducted tests and observed the physical properties of minerals. I combined my observations to identify the mineral samples based on their hardness, streak, color, and luster, and on how they break. I also identified rock samples based on their physical properties, such as grain size and foliation. I learned that the properties that are used to classify or group minerals and rocks can also be used to identify them. I also learned that the physical properties of rocks can tell us how they were formed.

explination: i took the test
