Answer:
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

Answer:
(-7,4)
Step-by-step explanation:
MN is 4/9 NP so
To find the x value
-19 and 8 are 27 apart and 27(4/9)=12
so you add 12 to the x value of P so 12+-19=-7 so the x value of N is -7
so the same for the y value
12 and -6 are 18 apart
18(4/9)=8 so you subtract 8 from the y value of P
12-8=4
so the y value N is 4
so N is
(-7,4)
These 3 problem I have answered have been almost the same except the numbers do you not understand how to do these problems and if not I can help you understand for the last question?
