determine if (-3/10,-2 is a solution to 10x,-9 =15
What you wrote makes no sense to me. Where is y in you equation? What is the comma about? Where is the right parenthesis?
i guess i need to know what solution that i will need out of this equation will add up to the solution
In the lab, Jessica has two solutions that contain alcohol and is mixing them with each other. She uses times as much Solution A as Solution B. Solution A is alcohol and Solution B is alcohol. How many milliliters of Solution B does she use, if the resulting mixture has milliliters of pure alcohol?
