Terry’s 7th grade class started out with 40 students. Over the last 4 months the class has seen a 30% decrease in students. How many students are now in Terry’s class?

28 students

Step-by-step explanation:

30% is equal to .3

40 x .3 equals 12

This means the class has lost 12 students.

40 - 12 is 28.

Another way:

Because the class has lost 30% of it's students, you know that the class is 70% of it's original capacity.

70% is equal to .7

40 x .7 is 28

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)
