Answer:
3.78
Step-by-step explanation:
How you do this problem is by simply multiplying 14% by 27. You have to remember that 14% is equivalent to 0.14, so you have to do 0.14 * 27 and you will get 3.78.
13x < 18x -24 -6
13x < 18x -30
13x - 18x < -30
-5x < -30
x = 6
Do 100-45 and you get 55. So it is 55 classrooms that are not Math and Science.
