Step-by-step explanation:
The two like fractions can be set as x and y (just to use two variables).
One of them is 
, though, so we can set one of the variables equal to that value (I'm just going to make 
, it doesn't matter which variable you use).
We also know that adding the two variables gives us 
so now we can make an equation.

i took the quiz
It looks as if it has to be the first choice. Because its asking for you to find "X" which is greater than 2. Good luck!
Answer:
20 children.
Step-by-step explanation:
We can solve this using an equation or simple mental math:
The equation: x=children x+20=adults
x + (x+20) = 60
2x + 20 = 60
2x = 40
x = 20
Mental Math: 40 plus 20 is 60 and 40 is 20 more than 20 so there are 40 adults and 20 children.
A= 9000m squared and A= base(width)*hight or A=b*h so divide 9000m by 60m
9000/60=(1050) 60 120 180 240 300 360 420 480 and so on
1 2 3 4 5 6 7 8
