They each have 30 kids per class, How many classes are they teaching a day?
Because we are looking at money and amount there will be 2 sepret equations that can be solved using the Elimination or Substitution method.
$4,800=x18+y33 would be the first one that is dealing with money.
200=x+y
I personally find the substitution method easier but whatever you like could work. First things first, get Y alone in ONE equation, you can choose whatever one you want but I am going to use the bottom one cause it is the easiest.
200=x+y
-x -x subtract x from both sides
200-x=y. y is now alone making it easy to switch the equation
y=200-x this equation is the value of y
Now plug in the value of y in the top equation,
4,800=x18+33(200-x) now solve this equation
4,800=x18+6600-33x
4,800=-15x+6600
-6600. -6600
-2200=-15x. divide by -15
x=146.67
now since we have the x value we can plug it in to the bottom equation.
200=146.67+y
-146.67
y=53.33
these coordinates are the intersection point so it'll give ya the number.
hope this helped a little
The area is 140.

The formula for density is:
Mass/Volume, or in other terms, mass divided by volume.
So, lets look at our numbers:
We know our mass is 84 grams, and our volume is 12 cc. So, all we need to do is divide 84 by 12, which is 7.
So, the density is 7.
