12y-6= -30
12y-6+6= -30+6
12y= -24
12y -24
—— = ——-
12 12
Y= -2

Answer Bank: Addition Property of Equality, Subtraction Property of Equality, Multiplication Property of Equality, Division Property of Equality, Simplifying, Distributive Property

The required reasons are Distributive Property, Addition Property of Equality, Simplifying, Division Property of Equality, Simplifying respectively.

Given:

The given equation is:

Several steps of solving the above equation are given.

To find:

The reasons for each step.

Explanation:

We have,

Using distributive property, we get

Add 6 on both sides.

Divide both sides by 12.

Therefore the steps and reasons are shown below:

Step-by-step explanation:

3(4y-2)= -30  

12y-6= -30  Distributive Property

12y-6+6= -30+6   Addition Property of Equality   (the 6 on each side)

12y= -24    Simplifying  

12y -24

—— = ——-           Division Property of Equality    (divide by 12 on each side)      

12          12

Y= -2                Simplifying,  

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.
