2x - y = 8<br>x + 2y = 4<br>For the system of equations above, what is the value<br>of x + y​
slava [35]

Answer:

x + y = 4

Step-by-step explanation:

2x - y = 8 | ×1 |

x + 2y = 4 | ×2 |

2x - y = 8

2x + 4y = 8

__________--

-5y = 0

y = 0/-5

y = 0

2x - y = 8

2x - 0 = 8

2x = 8

x = 8/2

x = 4

x + y

= 4 + 0

= 4

​Anzio, Inc., has two classes of shares. Class B has 10 times the voting rights as Class A. If you own 10 % of the Class A share
Neko [114]

Answer:

19.1\%

Step-by-step explanation:

Let x represent voting rights of class A.

We have been given that class B has 10 times the voting rights as Class A. So voting rights of class B would be 10x.

We have been given that you own 10% of the Class A shares, that will be equal to 10% of x as:

10\%\text{ of }x=\frac{10}{100}x=0.10x

We are also told that you own 20% of the Class B​ shares, that will be equal to 20% of 10x as:

20\%\text{ of }10x=\frac{20}{100}\cdot 10x=2x

Sum of percentage of both class voting rights would be 0.10x+2x=2.10x.

Total voting rights of both classes would be x+10x=11x.

Now we need to find 2.10x is what percent of 11x.

\text{Percentage of the total voting rights that you hold}=\frac{2.10x}{11x}\times 100\%

\text{Percentage of the total voting rights that you hold}=\frac{2.10}{11}\times 100\%

\text{Percentage of the total voting rights that you hold}=0.19090909\times 100\%

\text{Percentage of the total voting rights that you hold}=19.090909\%

\text{Percentage of the total voting rights that you hold}\approx 19.1\%

Therefore, you hold approximately 19.1\% of the total voting rights.

Tata Darka ma 20 m siatki ogrodzeniowej.Jakie wymiary w metrach,wyra¿one liczbami naturalnymi,powinien mieæ prostok¹tny warzywni
grin007 [14]

Answer:

Hence the dimensions are 5×5 i.e. 5 meters and 5 meters such that its field would be as large as possible.

Step-by-step explanation:

Darek's dad has a 20 m fencing mesh.

Since we have to make a rectangular garden with he help of fencing the garden using this mesh, that means perimeter of this garden is 20 m.

i.e. 2( l+b)=20

also we have to fenced in such a way that its field would be as large as possible.

ie. it has the largest Area.

Now we will start from the dimensions possible as:

9×1 whose area will 9 m^2 (since Area=l×b)

Next dimension will be:

8×2 whose area will be 16 m^2

Next will be:

7×3 whose area will be 21 m^2

Next will be:

6×4 whose area will be 24 m^2

Next will be:

5×5 whose area will be 25 m^2

Next will be:

4×6 whose area will be same as of 6×4.

Hence, we get the maximum area to be 25 m^2 which is obtained when the dimensions are 5×5.
