The following are the ages (years) of 5 people in a room:
25, 22, 13, 14, 21
A person enters the room.
The mean age of the 6 people is now 22.
What is the age of the person who entered the room?
I
years

Answers

Answer 1

Answer:

Step-by-step explanation:

First add all of the numbers together

25+22+13+14+21=82

Now add a variable like X since we don't know the age of the sixth, and divide it by 6 since there are 6 people in the class.

82+X/6=22

(22 is the mean age)

Now solve for the equation

82+X=132

so X =50

The circunference is represented by the equation is [tex]x^{2}+y^{2}-6\cdot x +4\cdot y +9=0[/tex].

The graph of this function is presented in the attachment.

Step-by-step explanation:

The general equation of the circunferece is defined by the following formula:

[tex]x^{2}+y^{2}+A\cdot x + B\cdot y + C = 0[/tex] (1)

We can determine the value of the coefficients by knowing three distinct points: [tex](x_{1}, y_{1}) = (3,0)[/tex], [tex](x_{2},y_{2}) = (5,-2)[/tex], [tex](x_{3},y_{3}) = (1, -2)[/tex]

The system of linear equations is:

[tex]3\cdot A + C = -9[/tex] (2)

[tex]5\cdot A -2\cdot B + C = -29[/tex] (3)

[tex]A -2\cdot B + C = -5[/tex] (4)

The solution of this system is: [tex]A = -6[/tex], [tex]B = 4[/tex], [tex]C = 9[/tex].

The circunference is represented by the equation is [tex]x^{2}+y^{2}-6\cdot x +4\cdot y +9=0[/tex].

This is the exterior angle theorem, so

2x=78

x=39

sooooooooooooo

39+22=61 degrees

61 degrees

Answer:

21

Step-by-step explanation:

First set up the equation

130 + x + 30 + x + 22 = 180  (triangle angles always add up to 180)

then start to solve to find x

130 +2x + 30 + 22 = 180

182 + 2x = 180

-182          -182

2x = -2

/2     /2

x = -1

Then just plug it back into the equation

Answer:

x=3

y=1

Step-by-step explanation:

-2x - 7y = -13

3x + 6y = 15

3(-2x - 7y = -13) = -6x - 21y = -39

2(3x + 6y = 15) = 6x + 12y = 30

-6x - 21y = -39

----------------------  The -6x and 6x cancel out, 12 - 21 is equal to 9, 30 - 39 = -9

6x + 12y = 30

Therefore, you can say that -9y = -9 so y = 1

FInally, plug that back into either one of the original equations:

Step-by-step explanation:

The given equation of a line : [tex]y+3= -5(x-1)[/tex]

The equation of a line in slope -intercept form: y=mx+c, where m= slope , c=y-intercept.

We first use distributive property(a(b+c)=ab+ac) to simplify the given equation, we get

[tex]y+3=-5x+5[/tex]

Subtract 3 from both sides, we get
