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.

The complete question is
"Lisa has $150 at most to spend on clothes. She wants to buy a pair of jeans for $58 and will spend the rest on t-shirts that cost $14 each.
Explain what your solution means using complete sentences. How many t-shirts can she buy? Focus your answer on the difference between an equation and an inequality."
The expression that represents the number of t-shirts that Lisa can purchase is 14x + 58 = 150. The number of shirts that can be bought is 6.
<h3>What is a system of equations?</h3>
A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
Lisa has $150 at most to spend on clothes. She wants to buy a pair of jeans for $58 and will spend the rest on t-shirts that cost $14 each.
Let the number of shirts be x. The expression will be:
= (14 × x) + 58 = 150
14x + 58 = 150
Solving the expression will be:
14x + 58 = 150
14x = 150 - 58
14x = 92
x = 92/14
x = 6.5
The number of shirts that can be bought is 6.
