-6x+6y=6
-6x + 3y=-12
???

x=5 y=6

Step-by-step explanation:

Need to get rid of one variable to find one first. So I multiplied the second equation by -2 to get rid of y. So second equation becomes 12x-6y=24. add that to the first equation.

6x+6y=6

12x-6y=24

6x=30      then divide

x=5

then plug x into the original equation to get y.

-6(5) +6y=6

-30+6y=6    add 30 to both sides

6y=36       then divide

y=6

then put both into the original to make sure it makes sense

-6(5) +6(6)=6

-30+36=6

6=6

correct

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
