The steepest part of any walking trail in Craters of the Moon National Monument rises 9 yards vertically for every 50 yards traveled horizontally. If one particular part of the trail covers a horizontal distance of 25 yards, how much of a vertical rise is covered? BRAINLIEST! PLS SOLVE ASAP

Colby and jaquan are growing bacteria in an experiment in a laboratory. colby starts with 50 bacteria in his culture and the number of bacteria doubles every 2 hours. jaquan starts with 80 of a different type of bacteria that doubles every 3 hours. let x equal number of days. colbys experiment follows the model: a.) y=50*2^x b.) y=50*2^8x c.) y=50*2^12x jaquans experiment follows the model: a.)80*2^x b.)80*2^8x c.)80*2^12x

What is the solution to this system of equations? y= 2x - 3.5 x - 2y = -14

What is the value of x in the equation 1.5x+4-3=4.5(x-2)?
