<u><em>Answer:</em></u>
Open
<u><em>Explanation:</em></u>
An open equation is an equation that has variables and CAN be solved
<u>Example</u>: 2x = 4 ......> can be solved giving ......> x = 2
A false equation is one where both sides can NEVER be equal
<u>Example:</u> 15 = 2(3) + 1 ..........> 15 can never be equal to 7
A true equation is one having no variables and both sides are ALWAYS equal
<u>Example:</u> 2(3) + 1 = 2(2) + 3 ........> 7 will always be equal to 7
Now, the given equation is:
4y + 8 = 6y + 3
Let's try to solve is:
4y + 8 = 6y + 3
6y - 4y = 8 - 3
2y = 5
y = 2.5
Therefore, the given equation contains a variable and can be solved which means that it is an open equation

Step-by-step explanation:
Answer:
C. 134.04 
Step-by-step explanation:
The formula to calculate the volume of the cone is:
+) <em>Volume of a cone = 1/3 x Area of base x Height</em>
<em />
The base of the cone is a circle, so that the formula to calculate the are of the base is: <em>Area of base = </em>
x
The radius of the base is 4cm
=> <em>Area of base = </em>
x 4^2 = 3.14 x 16 = 16

The height of the cone is given equal to 8 cm
So the volume of the cone is:
+) <em>Volume of a cone = 1/3 x Area of base x Height = 1/3 x 16</em>
<em> x 8 = 134.04 </em>
<em />
<em />
So the answer is C
Those are adjacent angles. They will equal 180 degrees since they both ly on the same straight line. Straight line= 180 degrees.
10x-20+6x+8=180
Add 20 to both sides.
10x+6x+8= 200
Combine like terms.
16x=192
Divide both sides by 16.
x=12
I hope this helps!
