Answer:
54
Step-by-step explanation:
First, take the number 200. we can remove 20, because they didn't go to the exams.
Secondly, we have to find 70% of 180. This can be done by doing some math.
Let's do this by using fractions. 70/100 * 180 = 126.
Third, we find the other 30% by doing the same equation.
30/100 * 180 = 54
(This is the part where you thank me, and give your opinions, and maybe "brainliest" answer. :D)

Answer: 1.29n + 0.79w + 3.39b is the expression.
The total cost is $12.91
Step-by-step explanation: Substitute the number of pounds for each given supply. Multiply to get the individual amounts, then add all of those amounts to find the total cost.
1.29(2) + 0.79(4) + 2.39(3) = total
2.58 + 3.16 + 7.17 = 12.91
Step-by-step explanation:
Let a be the total score of Div. A
Let b be the total score of Div. B
given,
as equation 1.
and
as equation 2.
Now multiply equation 2 by 1/20 to eliminate b to solve for a.
take this new equation as equation 3.
now we will use equation 1 + equation 3 to eliminate b to solve for a.
Div.A total score = 600
Average Score = Total Score / Number of students.
