Answer:
There are 150 blue marbles in Alex's bag.
Step-by-step explanation:
Let
,
,
be the quantities of red, blue and yellow marbles, respectively. From statement we derive three rational equations for initial and final ratios:
Initial ratio
(1)
(2)
Final ratio
(3)
After some algebraic handling we get the following system of linear equations:
(1)
(2)


(3)
The solution of the system of linear equations is:

There are 150 blue marbles in Alex's bag.
The length would be 22 ft.
The width would be 7 ft.
A=lw
A=22(7)
A=154 ft^2
Y=-1/2+2
The y intercept is clearly 2 and you're going down 2 over two every time so your slope is -1/2.
