Multiply the equation (x-2y=10) by -1
-x+2y=-10
x+3y=5
The x’s cancel out
2y=-10
3y=5
Combine
5y=-5
Divide both sides by 5
y=-1
Plug in y to either original equation
x-2(-1)=10
x+2=10
Subtract 2 from both sides
x=8, y=-1
The fraction of the furniture sold that are tables is given by 1/2y / (1/3x + 1/3y)
<h3>Equation</h3>
Let
- number of chairs = x
- Number of tables = y
Number of tables and chairs sold = 1/2(x + y)
= 1/2x + 1/2y
- Fraction of chairs sold = 1/2x
- Fraction of tables sold = 1/2y
Furniture remaining = 1/3(x + y)
Fraction of tables sold = 1/2y ÷ 1/3(x + y)
= 1/2y ÷ 1/3x + 1/3y
= 1/2y × 1 / (1/3x + 1/3y)
= 1/2y / (1/3x + 1/3y)
Therefore, the fraction of the furniture sold that are tables is given by 1/2y / (1/3x + 1/3y)

Answer:
i dont know just study hard bro
Step-by-step explanation:
The answer for this question is 100
Given:
A prism has a base area of 
square units and a volume of 
cubic units.
To find:
The volume of the cylinder if the cylinder has the same base area and height.
Solution:
Volume of a prism is:
Where, B is the base area and h is the height of the prism.
The volume of cylinder is:
Where, r is the radius, h is the height of the cylinder and 
is the base area.
Since base area and height of the cylinder are same as the prism, therefore, there volumes are equal.
Hence the volume of the cylinder is cubic units.
