A. x = 9, y = 14; 11, 20

B. x = 14, y = 9; 11, 11

C. x = 14, y = 9; 6, 16

D. x = 9, y = 14; 6, 16

Answers

Answer:

So, the correct option is A. x = 9, y = 14 , Sides are 11 and 20

Step-by-step explanation:

P.S - the exact question is -

As given in the question ,

Side AB = Side AD

⇒y - 3 = x + 2

⇒y - x = 2 + 3 = 5

⇒y - x = 5                        .........(1)

Also, given

Side BC = Side CD

⇒2x + 2 = x + 11

⇒2x - x = 11 - 2

⇒x = 9

∴ equation (1) becomes

y - 9 = 5

⇒y = 5 + 9 = 14

⇒y = 14

∴ we get

x = 9, y = 14

Now,

as given ,

Side AB = y - 3

⇒ AB = 14 - 3 = 11

Side BC = 2x + 2

⇒ BC = 2(9) + 2 = 18 + 2 = 20

Side CD = x + 11

⇒ CD = 9 + 11 = 20

Side DA = x + 2

⇒DA = 9 + 2 = 11

∴ we get

The sides are 11 and 20

So,

The correct option is A. x = 9, y = 14 , Sides are 11 and 20

An investor has an account with stock from two different companies. Last year, his stock in Company A was worth $3820 and his stock in Company B was worth $2960. The stock in Company A has increased 15% since last year and the stock in Company B has increased 5%. What was the total percentage increase in the investor's stock account? Round your answer to the nearest tenth (if necessary).

Answers

Answer:

10.6%

Step-by-step explanation: Find new values:

3820(1+0.15)=\color{green}{4393}

3820(1+0.15)=4393

2960(1+0.05)=\color{blue}{3108}

2960(1+0.05)=3108

Last Year This Year

Stock A 3820 4393

Stock B 2960 3108

Total 6780 7501

\text{Find overall increase:}

Find overall increase:

6780(1+r)=7501

6780(1+r)=7501

\frac{6780(1+r)}{6780}=\frac{7501}{6780}

6780

6780(1+r)

​

=

6780

7501

Which of the following equations is equivalent to 2/3a - 7 = 1/3

Answers

Answer:

a = 11

Step-by-step explanation:

Given the equation 2/3a - 7 = 1/3

We are to find the value of a that satisfies the equation

2/3 a = 1/3 + 7

2/3 a = (1+21)/3

2/3 a = 22/3

2a = 22

a = 22/2

a = 11

Hence the value of a that satisfies the equation is 11
