find the sum of an arithmetic sequence 9, 15, 21, 27,…,183?

Answer:

y=30

x=60

Step-by-step explanation:

The triangle has all sides equal therefore all the angles are equal.

For all the angles to be equal and add up to 180 (sum of angles in a triangle is 180), each angle has to be 60.

Therefore y=90-60

=30

x=180-(30+90)

=60

none cuz Travis don't sell papers

Step-by-step explanation:

I'm kidding so 38 ÷ 2 = 19 so 38 + 19 or 19 × 3 = 57

Answer:

The answer is B, $0.26

Step-by-step explanation:

$48 * 12 =$576

- 12 months in a year

$223,050 / $100 =$2230.50

$576 / $2230.50 =$0.26

Answer:

X=6

Step-by-step explanation:

Hope this helps.

Answer:

x = K

Step-by-step explanation:

If,

x = 6

and 6 = k

=> x = 6 = k

=> x = k

The Transitive Property of Equality states the same fact as:

"If two units are equal to each other and the second unit is equal to a third unit, then the first unit is also equal to the third unit."

Answer:

6/20. (simplified is 3/10)

Step-by-step explanation:

Answer:

Y = -44 (hope this helps :)

Step-by-step explanation:

=2Y+88

We move all terms to the left:

-(2Y+88)=0

We get rid of parentheses

-2Y-88=0

We move all terms containing Y to the left, all other terms to the right

-2Y=88

Y=88/-2

Y=-44

Answer:

its D

Step-by-step explanation:

I got this correct in schoology

Explanation:

This is a 30-60-90 triangle as shown by the angles. These types of triangles have their shortest leg opposite the smallest angle, and the connection between the short and long legs is

long = short*sqrt(3)

We see that the long leg is 16*sqrt(3) units long, which must mean the short leg is 16 units. This doubles to 32 when we go from short leg to hypotenuse

hypotenuse = short*2

Answer:

x=[tex]\frac{1}{12}[/tex]

Step-by-step explanation:

1/2x - 5 = 10 - 3/4x

4x/2x - 5 × 4x = 10 × 4x - [tex]\frac{3 x 4x}{4x}[/tex]

2 -5 × 4x = 10 × 4 - 3

2 - 20x = 40x - 3

-20x - 40x = -3 - 2

-60x = -3 - 2

-60x = -5

x = [tex]\frac{-5}{-60}[/tex]

x = [tex]\frac{1}{12}[/tex]

Answer:

Step-by-step explanation:

im not a genius at math, but i will give it a shot

scenario 3:

let m= cost per minute for WDE, let b= flat fee for WDE

42.5=50m+b

65=100m+b

subtract the two equations

65-42.5=50m

m= .45 (this is the cost per minute on WDE wireless)

plug in m=.45 into the first equation

42.5=50(.45)+b

b= 20 (this is the fixed monthly fee for WDE wireless)

HTR offers .25 per minute, whereas WDE offers .45 a minute which means that HTR has the cheaper per minute rate

htr has the equation .25x+30

WDE has the equation .45x+30

set them equal to each other and solve for x .25x+30=.45x+20

x= 50 minutes

Scenario 4:

Same deal as last question, let m=cost/movie, b=flat fee

41.25=5m+b

57.5=10m+b

subtract the two equations and solve for m

57.5-41.25=10m-5m+b-b

m= 3.25 (slope)

b=25  (y intercept)

y=3.25x+25

y=3.25(125)+25  = 431.25

3.25x+25=2.75x+35

.5x= 10

x= 20

Answer:

Graphs shown below.

4.) x-intercept: (3,0)  y-intercept: (0,-2)  slope: 2/3

5.) x-intercept: none  y-intercept: (0,4.5)  slope:0

6.) x-intercept: (3,0) and (-1,0)  y-intercept: (0,-1)   slope: none

Step-by-step explanation:

look at the attached image

Answer:

1400

Step-by-step explanation:

2/5×1000=400

1000+400=1400

Step-by-step explanation:

Let the new quantity be x.

x:1000=2:5

x/1000=2/5

(multiply both side by 1000)

[tex]1000 \times \frac{x}{1000} = 1000 \times \frac{2}{5} [/tex]

[tex]x = 400[/tex]
