Solve for X - ln (2x-15) = - 3

The variable z is directly proportional to x, and inversely proportional to y. when x is 4 and y is 13, z has the value 1.2307692307692. what is the value of z when x= 9, and y= 20

2x - 20 = 32 20 - 3x = 8 6x - 8 = 16 -13 - 3x = -10

The ratio of men to women working for a company is 4 to 5 . if there are 90 women working for the company, what is the total number of employees?
