The greater of two consecutive integers is nine more than twice the lesser integer. what are the two integers?

-7 and -8

Step-by-step explanation:

Generally with this kind of problem it is helpful to construct equations representing the words.

Let's let:

Lesser integer = X

Greater integer = Y

The integers are consecutive, meaning that they are only one integer (number) apart. So,

Y = X+1

From the problem, we know that

Y = 9 + 2X

Now, we can sub in the equation from above.

(X + 1) = 9 + 2X

We now solve for X:

1 - 9 = 2X - X

-8 = X

Y = -8 + 1

Y = -7

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 !
