Answer:

(-1, -2)

Step-by-step explanation:

-2x + y = 0

y = 2x

5x + 3y = -11

5x + 3(2x) = -11 => 5x + 6x = -11

11x = -11

x = -1

-2(-1) + y= 0

2 + y = 0 => y = -2

5(x + 6) – 2x = 3(x + 10)

Maslowich

Answer:

x = 0

Step-by-step explanation:

We know: 5(x + 6) – 2x = 3(x + 10)

Distribute: 5x + 30 - 2x = 3x + 30

Rearrange equation: 5x - 2x - 2x = 30 - 30

Combine like terms: 1x = 0

Divide: x = 0

Darla has four buckets shaped like cylinders she is filling the buckets with water by using a scoop shaped like a cone if the co

padilas [110]

Answer:

12 Scoops

Step-by-step explanation:

Darla has 4 Cylinder Shaped Buckets

Volume of the Cylinders $=4*\pi r^2h$

The scoop is cone shaped and:

Volume of the Cone Scoop $=\frac{1}{3} \pi r^2h$

Since the radius and height of the cone scoop and cylindrical buckets are the same,

The number of Cone Scoops it will take to fill the buckets is:

Total Volume of Buckets/Volume of Cone Scoops

$=\dfrac{4*\pi r^2h}{\frac{1}{3} \pi r^2h} \\=4 \div \frac{1}{3}\\=12$

It will take 12 Scoops to fill the 4 buckets.
