the answer is B these are the steps of getting your answer
No, it is not a solution.
Let's plug 5 into the equation where p is.
10(5) - 2 > 97
50 - 2 > 97
48 > 97
This is false, 48 is less than 97.
You see what the average is in each class. (Divid students and classes) and add them together and divid by four. You should get 18 if you round to the whole number.
Answer:
n = 3.8
Step-by-step explanation:
0.3(n - 5) = 0.4 - 0.2n
Distribute
.3n - 1.5 = .4 - .2n
Add .2n to each side
.3n +.2n -1.5 = .4 -.2 +.2n
.5n -1.5 = .4
Add 1.5 to each side
.5n -1.5 +1.5 = .4+1.5
.5n = 1.9
Divide each side by .5
.5n/.5 = 1.9/.5
n =3.8
