How do I find x In these two problems?

How Do I Find X In These Two Problems?

Answers

Answer 1

Answer:

#1: 146 degrees #2: 111 degrees

Step-by-step explanation:

The angles of a heptagon (a shape with 7 sides) are supposed to add up to 900 degrees, so just add up all the sides that you know and subtract it from 900 and you will have x! Do the same thing with the second one, except is is a hexagon and all the angles should add up to 720 degrees. (Don't forget to add the right angle, which is 90 degrees) So add up all the sides you know and subtract from 720 to get x.

P.S. If correct, please give Brainliest?

Answer 2

Answer:

N = number of sides

The sum of the interior angles of a polygon is equal to (N x 180)-360.

The first problem has 7 sides so the interior angle total = 900 degrees.

Add up all the known interior angles:

96+105+161+123+155+114+x = 900

x = 900-754 = 146 degrees

The second problem has 6 sides so the interior angle total = 720 degrees.

Add up all the known interior angles:

127+40+202+90+150+x = 720

x = 720-609 = 111 degrees

Answers

Answer: 25

Step-by-step explanation:

6 x 2 = 12

8 + 4 = 12

therefore, (2 x 6) + (8 + 4) + 1 = 12 + 12 + 1

which gives 25

You first have to follow PEMDAS
Start with parenthesis, (2x6) and (8+4)
Solve 2x6 and 8+4
Add 12+12+1
Which gives you 25

how do you simplify 1 1/8 x 3 2/3 someone please help me!

Answers

Answer:

4 1/8

Step-by-step explanation:

1 1/8 x 3 2/3 = ?

9/8 x 11/3 = 99/24

99/24 = 4 1/8

Answer:

1. find the least common denominator for the left-hand side fraction. This brings you to 8/8x + 3x/8x = 1/2

2. Add the numerator on the left-hand side of this equation, (8+3x)/8x = 1/2

3. Multiply both sides by 2, that will lead you to (8+3x)/4x =1/1

4. Multiply both sides by 4x, we get 8+3x=4x

5. Finally, subtracting 3x from both sides simplifies the equation to x=8. Note that this is as simple as this expression can get so you can not go any further, therefore 1/x+3/8=1/2 simplifies to x=8.

If M (4.2) is the midpoint of AB and A (-5, -3), find the coordinates of B.

Answers

Given:

M(4,2) is the midpoint of AB and A(-5, -3).

To find:

The coordinates of B.

Solution:

Let the coordinates of point B are (a,b).

Midpoint formula:

[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]

M(4,2) is the midpoint of AB and A(-5, -3).

[tex]M=\left(\dfrac{-5+a}{2},\dfrac{-3+b}{2}\right)[/tex]

[tex](4,2)=\left(\dfrac{-5+a}{2},\dfrac{-3+b}{2}\right)[/tex]

On comparing both sides, we get

[tex]4=\dfrac{-5+a}{2}[/tex]

[tex]8=-5+a[/tex]

[tex]8+5=a[/tex]

[tex]13=a[/tex]

And,

[tex]2=\dfrac{-3+b}{2}[/tex]

[tex]4=-3+b[/tex]

[tex]4+3=b[/tex]

[tex]7=b[/tex]

Therefore, the coordinates of point B are (13,7).

Answer: Choice B) Investment decreases by 3% each month

=====================================================

Explanation:

We won't use the value 2500 at all.

The base of the exponential is 0.97

Set this equal to 1+r and solve for r

1+r = 0.97

r = 0.97-1

r = -0.03

The negative r value indicates we have exponential decay, so the value of the investment decreases by 3% each month.

Let's say you had $100 to start off. This would mean the investment would be worth $97 after one month is up.

a/b = -15/-5

a/b = 15/3

a/b = 5/5 * 3

a/b = 1*3

a/b = 3
