Answer:

8w² < 4w(150-w)

Step-by-step explanation:

Square area of living : w · w = w²

Money spent : 8 · w²

Square area of artichokes : (150 - w) · w

Money earned : 4 · w · (150 - w)

Julia manages to save some money every week. That means that the money earned is bigger than the money spent ( the money spent is less than the money earned)

8 · w² < 4 · w · (150 - w)

Step-by-step explanation:

The ratio of long side to hypotenuse is the same for all of the triangles in the figure.

AD/AB = AB/AC

AB^2 = AD·AC = 30·36

AB = 6√30 ≈ 32.863

Solve the system by substitution.<br> 4y =<br> 5x -10y =-50

Trava [24]

Answer:

$x = -20 ; y =-5$

Step-by-step explanation:

Eqn. 1 ----> 4y = x

Eqn. 2 ----> 5x-10y = -50

(Simplifying eqn.2 further)

$=>5(x-2y)=-50$

$=>x-2y=\frac{-50}{5} =-10$

(Substituting the value of x from eqn. 1)

$=>4y-2y=-10$

$=>2y=-10$

$=>y =\frac{-10}{2} =-5$

Now, substituting the value of y in eqn. 1 ,

$x = 4*(-5)=-20$
