At a certain university the student to teacher ratio is 16: 1. if there are 2,000 students and rolled how many teachers must be employee to maintain this ratio

Essentially, the equation is 2000/x = 16/1

We can use cross multiplication to show that 2000 = 16x

x = 125

There are 125 teachers.

yeah and the opposite of cheating is studying ( you should try it some time)

step-by-step explanation:

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
