Answer:
the correct answer is x=5
When solving for a variable, you want to get it isolated (i.e. alone). Here are the steps to do this equation...
1. Given: kx-3=5
2. Add three to both sides to remove the -3, and this gives you kx=8
3. Since the x is being multiplied by k, you want to do the inverse and divide both sides by k, and this gives you x=8/k
So this means that your answer is D

Hello! And thank you for your question!
First we are going to redo the equation:
<span><span><span>y<span><span>^3</span><span></span></span></span>−3<span>y^<span><span>2</span><span></span></span></span>(3)+3(y)×<span>3<span><span>^2</span><span></span></span></span>−<span>3<span><span>^3</span><span></span></span></span>=0
Then we are going to use Cube of Difference:
0 = (y - 3)^3
That take cube root of both sides:
0 = y - 3
Finally add 3 to both sides:
3 = y
Final Answer:
y = 3</span></span>
The volume of pyramid is 4000 inch³.
<h3>What is Volume?</h3>
Volume is a mathematical term that describes how much three-dimensional space an object or closed surface occupies. Volume is measured in cubic units like m³, cm³, in³, etc. Volume is sometimes referred to as capacity.
The capacity of an object is measured by its volume. For instance, a cup's capacity is stated to be 100 ml if it can hold 100 ml of water in its brim. The quantity of space occupied by a three-dimensional object can also be used to describe volume.
Given:
base = 20 inches
height = 30 inches
Now, volume of pyramid
Volume = a²h/3
Volume = 20 x 20 x 30 /3
Volume = 400 x 10
Volume = 4000 inch³
Hence, the volume of pyramid is 4000 inch³.
