I only need the awnser for questions 4 and 2 because i dont get them

2) 20 students

4) 28 students

Question 2 is 25% - but it's asking how many. If you know the total number of students multiply that times .25 and that number is your answer. So .25 x 80 = 20

Question 4 is 35% also multiplied times the total number of students. So it would be the total number of students multiplied times .35.

So .35 x 80 = 28

Both of these questions want the number of students, not the percent.

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17

hope this

a28=58

step-by-step explanation:

a1=a1+(n-1)d

a28= 4+ (28-1)2

a28=4+(27)(2)

a28=4+54

a28=58
