Let the total number of teachers be x
Given:
The ratio of the number between male and female teachers is 5:9
Then the number of female teachers is 81
So 9/14*x=81
or, x=81/9*14
or, x=9*14
Therefore x=126
So the total number of teachers is 126.
Hence the number of male teachers =
5/14*126
=5*9
=45
Hence, the number of male teachers is 45.

Answer:
x^3+6x^2+9x
if you are trying to find the original function
if not, and you are trying to find the zeros is
x=-3
x=0
Step-by-step explanation:
multiply x(x+3)
x^2+3x
then multiply that by x+3 and that should give you the answer
Answer:
Reduce the greatest common factor on both sides of the equation: (2x+y=12
(x-3y=27
Rearrange like terms to the same side of the equation: (2x+y= 12
(x=27+3y
Substitute into one of the equations: 2(27+3y)+y=12
Apply Multiplicative Distribution Law: 54+6y +y=12
Rearrange unknown terms to the left side of the equation: 6y+y=12-54
Combine like terms: 7y=12-54
Calculate the sum or difference: 7y=-42
Divide both sides of the equation by the coefficient of variable: y= -42÷7
Calculate the product or quotient: y= -6
Substitute into one of the equations: x=27+3×( -6)
Remove the parentheses: x=27-3×6
Calculate the product or quotient: x=27-18
Calculate the sum or difference: x=9
The solution of the system is: x=9
y=-6
Answer:
x=9
y=-6
