Answer:
40 rows will hamsters fill
Step-by-step explanation:
As per the statement:
There are 486 hamsters at a private showing of a new documentary about humans.
⇒Total number of hamsters = 486
It is also given that there are 12 seats in each row.
then;
They will fill = 
Therefore, the best estimate the rows will hamsters fill is 40 rows.
C
6x^2-13X-5=0
(3X+1)(2X-5)
3x-1=0
X=1/3. 2x-5=0. X= 5/2
1. Multiply the second line by 4: 4x+4y=16. They are the same line so there are infinitely many solutions.
2. Substitute for y.
x+(2x+10)=-2
3x+10=-2
3x=-12
x=-4
Plug x in
-4+y=-2
y=2
Final answer: (-4,2)
3. The answer is the first one because the solution is always where two lines intersect. The crossing of the x axis, y axis, and origin are irrelevant.
4. 2x+4=3x+1. This is because both equations define the value of y and therefore must be equivalent.
5. Infinitely many solutions. If you multiply the second equation by -3, you can tell it's coinciding or the same line.
Answer:
