The distance from -21 to 18 would be 39 units ( -21 to 0 is 21 and from 0 to 18 is 18 , 21 +18 = 39)
To find the midpoint distance, divide the total distance by 2:
x = 39/2
x = 19.5
Now to find the midpoint, either add 19.5 to -21 or subtract 19.5 from 18.
Midpoint = -1.5
Answer:
x = 12

Answer:
60
Step-by-step explanation:
There are 2+5 = 7 ratio units of students. If we multiply the numbers by 5, we can have a total of 35 ratio units of students: 10 : 25.
Now, we can substitute this into the ratio of teachers to students:
teachers : students = 3 : 35
teachers : (male students : female students) = 3 : (10 : 25)
Then the number of teachers is seen to be 3/25 of the number of female students:
(3/25)(500) = 60 . . . teachers
here it is :)
