Answer:

x = 3

y = 0

Step-by-step explanation:

The method of substitution is when one solves an equation for one of the variables, and then substitutes the expression into the other equation. After doing so, one will solve the other equation for the remaining variable and then backsolve for the first variable.

4x + 2y = 12

x = y + 3

The second equation is already sovled for parameter (x), subttiute this into the other equation,

4(y + 3) + 2y = 12

Distribute,

4y + 12 + 2y = 12

Simplify,

6y + 12 = 12

Inverse operations,

6y + 12 = 12

-12

6y = 0

/6

y = 0

Backsolve for (x), substitute the value of (y) into the equation for (x) and solve,

x = y + 3

x = 0 + 3

x = 3

The figure below has a height of 18 inches and a volume of 864 cubic inches. What is the area of the base of the figure?
kodGreya [7K]

Answer:

48 sq. in.

Step-by-step explanation:

Different figures (rectangular prisms, cylinders, triangular prisms etc.) have different volume formula. But what formula of "volume" do they come from??

It is:

Volume = Area of Base * Height

<u>Note:</u> we didn't specify any Area of Base formula because it depends. If base is circle, the area is different than if base was suppose a square. But this is the general formula of volume.

Now,

Given

Height = 18 inch

Volume = 864 cubic inch

We can write:

Volume = Area of Base * Height

864 = Area of Base * 18

Thus,

Area of Base = 864/18 = <u>48 sq. in.</u>

<u>This is what we are wanting, "area of base" (irrespective of the shape).</u>
