7) -6x + 6y=6 -6x + 3y=-12

Answer:

(5,6)

Step-by-step explanation:

-6x+6y=6

-6x + 3y =-12

Multiply the first equation by -1

6x-6y=-6

Add this to the second equation

6x-6y=-6

-6x + 3y =-12

---------------------

-3y = -18

Divide each side by -3

-3y/-3 = -18/-3

y =6

Now we need to find x

6x - 6y = -6

6x -6(6) = -6

6x -36 = -6

Add 36 to each side

6x-36+36 = -6+36

6x = 30

Divide each side by 6

6x/6 = 30/6

x =5

What is the volume of this cone?

Romashka-Z-Leto [24]

Answer:

3537.73 cubic in

Step-by-step explanation:

Given,

Diameter of the cone = 26 in

Radius of the cone = 26in ÷ 2 = 13 in

Height of the cone = 20 in

Therefore, volume of the cone

$= \frac{1}{3} \pi {r}^{2} h$

$= \frac{1}{3} \times 3.14 \times 13 \times 13 \times 20$

$= 3,537.7333333333 \: {in}^{3}$

<u>Approx. 3537 . 73 cubic in (Ans)</u>
