Answer:
Step-by-step explanation:
Hello there! The value of y is -5/4.
So, basically look at it like an ordered pair, (x, y). When we have (5, y), we have a value of x and are looking for a value of y. To do this, plug the value for x (5) into the equation and solve for y.
5x+4y-20=0
5(5)+4y-20=0
Now that you have the value for x, solve for y.
5(5)+4y-20=0 - Start by multiplying out the parenthesis.
25 + 4y - 20 = 0 - Next, combine like terms.
25 - 20 + 4y = 0
5 + 4y = 0 - Now, subtract 5 from both sides.
4y = -5 - Lastly, divide both sides by 4.
y = -5/4.
This is your final answer. I hope this helps and have a great day! :)

Answer:
40 students
Step-by-step explanation:
We do not count the counselors or the principal because they are not students, so we do 83 - 3 = 80, now it is just simple division, for every student there is a parent, so we divide 80 in half, 80 / 2 = 40 students :D
the answer is 640.
if you take 640 and multiply it by .23 (because of 23%), you get 147.2 which is exactly what you are looking for.
Hope this helps! :)
