The mean of five numbers is 4.
The five numbers are 1, 3,5,2 and x.
Find x.

Answers

Answer:

Step-by-step explanation:

In Order to gain the mean you would follow the formula:

Total Sum of all Numbers added together / Amount of integers.

In this case, you have 5 numbers 1, 3 , 5 , 2 , x .

I know that the overall sum of all your integers added together must equal 20, as 20 / 5 = 4.

1 + 3 + 5 + 2 = 11.

Therefore x must be 9.

1 + 3 + 5 + 2 + 9 = 20

20 / 5 = 4.

Just do 2/5 multiplied by 325 to get 130!! :)

Answer: Well if you do 325 ÷ 2/5 = 130. If you try process of elimination with the numbers you’d get the right answer! Like there’s no way you could do 325 - 2/5 cause you’d get 324.6, and adding it you’d get 325.4 so your only thing left to do is multiply :)

Angle 1=112 degrees

Step-by-step explanation:

Aight so we know angle 1 nd 2 equals 180 degrees, and because of some theorem with lines, angles 2 and 4 are both alternate exterior angles which means they are the same.

So if angle 4=5x+13

and angle 1=10x+2

and together they make 180, this should be your equation:

5x+15=180

simplify to get x=11

then since 1 =10x+2

multiply 11 by 10 then add 2

and your final answer should be 112 degrees

hope this helps

What is the solution to the system of equations graphed below?

y = 4x + 11

y = -2x - 1

Answers

Answer:

Step-by-step explanation:

y = 4x + 11, and y = -2x - 1, so

4x + 11 = -2x - 1

6x + 11 = -1

6x = -12

x = -2

y = 4x+11 = 3

y = 4x + 11

y = -2x - 1

4x + 11 = -2x - 1

4x + 2x = -1 - 11

6x = -12

x = -12/6

x = -2

y = 4x + 11

y = 4(-2) + 11

y = -8 + 11

y=3

Answer is (-2,3).

What integers could be represented by point Y?

please help asap

Answers

Answer:

[tex]y = 3[/tex] or [tex]y =-3[/tex]

Step-by-step explanation:

Given

x = midpoint of -5 and 11

y = absolute value of x

Required

Determine the value of y

First, calculate x.

[tex]x = \frac{1}{2}(-5 + 11)[/tex]

[tex]x = \frac{1}{2}(6)[/tex]

[tex]x = 3[/tex]

y can then be represented as:

[tex]|y| = x[/tex]

[tex]|y| = 3[/tex]

Split:

[tex]y = 3[/tex] or [tex]-y = 3[/tex]

[tex]y = 3[/tex] or [tex]y =-3[/tex]
