a,3x+2,b form an arithmetic sequence.if the common difference is 2x - 1 , what is A equal to?​

Answers

Answer 1

Answer:

x + 3

Step-by-step explanation:

3x+2 is the 2nd term

2x-1 is the commind difference (d)

so you just need to substract it

3x+2

-(+2x-1) -------transpose -2x+1

3x+2

-2x+1

---------

x+3

Answer 2

Answer:

a is equal to x + 3

Step-by-step explanation:

Arithmetic Sequences

The arithmetic sequences are identified because any term n is obtained by adding or subtracting a fixed number to the previous term. That number is called the common difference.

We are given the sequence:

a, 3x+2, b

And the common difference is 2x-1

Subtracting the second and the first terms:

3x + 2 - a

We can find the common difference since it's given:

3x + 2 - a = 2x - 1

Solving for a:

- a = -3x - 2 + 2x - 1

- a = -x - 3

a = x + 3

a is equal to x + 3

Simplify the midpoint of PR.
Q (2b, 2c)
R (2a+2b, 2c)
Pl(0,0)
S (2a, 0)

Answers

Answer:

The midpoint of PR is;

(a + b, c)

Step-by-step explanation:

Here, we want to get the coordinates of the midpoint of PR

To get these, we make use of the midpoint formula

Mathematically, that will be;

(x,y) = (x1+y1)/2, (x2+y2)/2

(x1,y1) = (0,0)

(x2,y2) = (2a+2b, 2c)

The midpoint is thus;

(2a+2b)/2 , 2c/2

= (a + b, c )

(a+b, c)

Answer:

W = 10 cm

Step-by-step explanation:

Area of a Triangle and a Rectangle

The area of a triangle of base B and height H is:

[tex]\displaystyle A_t=\frac{BH}{2}[/tex]

The area of a rectangle of width W and length L is:

[tex]A_r=WL[/tex]

We are given the base of the triangle B=6 cm and the height H=8 cm, thus the area is:

[tex]\displaystyle A_t=\frac{6*8}{2}= 24\ cm^2[/tex]

The area of the rectangle is 5 times the area of the triangle, thus:

[tex]A_r=5*24\ cm^2=120\ cm^2[/tex]

If we know the area of the rectangle and its length, we can find the width by solving for W:

[tex]\displaystyle W=\frac{A_r}{L}[/tex]

The rectangle has a length of L=12 cm, thus:

[tex]\displaystyle W=\frac{120}{12}=10\ cm[/tex]

W = 10 cm

It rained nine days in the month of April. Based on this, what is the probability that it does not rain on the first day of May? *

Answers

Answer: 0.7

Step-by-step explanation:

April has 30 days, and we know that it rained in 9 of them.

Then the probability that there will be rain in a random day, can be estimated as the quotient between the number of days where was rain and the total number of days, this probability will be:

P = 9/30 = 0.3

And we can extrapolate this probability to May.

Then we can estimate that the first day of May, the probability of rain will be around 0.3

Then the probability that it does not rain in the first day of may will be:

1 - 0.3 = 0.7

Ifa rectangle measures 20 meters by 48 meters, what is
the length, in meters, of the diagonal of the rectangle?

Answers

Answer:

[tex]52m[/tex]

Step-by-step explanation:

We can use the Pythagorean theorem to find the length of the diagonal since drawing a diagonal across a rectangle results in two right angle triangles.

Length of diagonal [tex]= \sqrt{20^2+48^2}[/tex] (The length of the diagonal can be thought of as the hypotenuse of one of the right angle triangles)

[tex]=\sqrt{2704}[/tex]

[tex]=52 m[/tex]

Step-by-step explanation:

im not sure with A I mean, forming an equation, I guess it should be 3x+4=22 that's all as texted and for B

what I did was subtract 4 from 22 which I got 18 and then I divided 18 with 3, since the question said it was multiplied by 3.

22-4=18.

18÷3=6. 6×3=18

In the parallelogram below, x=​

Answers

Answer:

23°

Step-by-step explanation:

By interior angle sum postulate of a triangle.

x = 180° - ( 124° + 33°)

x = 180° - 157°

x = 23°

The value of x is 23°

What is the angle sum property of a triangle?

The angle sum property of a triangle states that the sum of interior angles of a triangle is 180°

Given here, in the given triangle separated by the diagonal in the parallelogram two angles are 33° and 124°

therefore by angle sum property, the value of the third angle is

is x=180°-(33°+124°)

   x= 23°

Hence, the value for x is 23°

line s has a slope of 7/4. Line t is perpendicular to s. What is the slope of line t?

Answers

Answer:

Step-by-step explanation:

The formula governing this situation is

m1 * m2 = - 1

Method One

So let m1 = 7/4

(7/4)*m2 = - 1                      Multiply by 4

7*m2 = -1*4                         Divide by 7

m2 = -4/7

Method Two

Most people teaching this try to get you to use reciprocals. If you know how to do that then the answer is much simpler.

7/4 m2 = -1                        Multiply by 4/7

4/7 * 7/4*m2 = - 1 * 4/7      

m2 = -4/7

However if you are not comfortable with reciprocals, then then the thing to do is to handle them the way I showed you in the first method.
