What is the 23th term of the sequence
{20, 16, 12.8, ... }

Answers

Answer 1

Step-by-step explanation:

[tex]an = a1 + (n - 1)d \\ d = a2 - a1 \\ a1 = 20 \\ a2 = 16 \\ d = - 4 \\ an = 20 + (n - 1) \times - 4 \\ an = 20 - 4n + 4 \\ an = 24 - 4n \\ a23 = 24 - 4 \times 23 \\ a23 = - 68[/tex]

Determine if 2 is a solution to the equation 4 = 8 - 6x

Answers

Answer:

No

Step-by-step explanation:

No, 2 is not the solution to the equation above. Because, if you multiplied 6 and 2 together, (also known as x) it will become 12. Then, you would have to subtract 8 by 12, which would make -4. That would end up looking something like this: 4 = -4. And 4 does not equal -4, so 2 would not be a/the solution. Hope this helps!

i need help on the math question if it's right I'll give brain.​

Answers

Answer:  \frac{2}{5}  ; or, write in decimal form:  0.4 .

Step-by-step explanation:

Rewrite as:

_______________________

    [tex]\frac{4x}{7} = \frac{8}{35}[/tex] ;

________________________

Now, "Cross-factor multiply":

that is:

_____________________

 → Given:   [tex]\frac{a}{b} =\frac{c}{d}[/tex]  ;

    → ad = bc ;  (b≠0 ; d≠0) ;

_____________________

As such:

 4x * 35 = 7 * 8 ;

_______________________

We can divide one side of the equatiuon by "4" ; and one side by "7" :

  [tex]\frac{4x*35}{4*7} = \frac{7*8}{4*7}[/tex] ;

_______________________

We can simplify the "left-hand side":

 "4/4 = 1 " ; and "35/7 = 5 " ; & we are left with "x * 5" ; or "5x " .

________________________

We can simplify the "right-hand side":

 "7/7 = 1 " ; and: "8/4 =2 " ; to get: "2/1" ; which equals "2".

_________________________

So; we have:  " 5x = 2 " ; Solve for "x" ;

__________________________

  Divide each side of the equation by "5" ; to isolate "x" on one ide of the equation; & to solve for: "x" ;

__________________________

  " 5x/5 = 2/5 " ;  We cancel out the "5x/5" to "1x"; which equals "x":

    → x = [tex]\frac{2}{5}[/tex]  ;  or, write in decimal format:  "x = 0.4" ;

___________________________

\frac{2}{5}

Answer:

[tex]x = 0.4[/tex]

Step-by-step explanation:

[tex]\frac{7}{4} x \frac{4}{7} = \frac{7}{4} x \frac{8}{35}[/tex]

Reduce the number with the greatest common factor 7

[tex]\frac{1}{4} x 4x= \frac{7}{4}x\frac{8}{35}[/tex]

[tex]x=\frac{7}{4}x\frac{8}{35}[/tex]

[tex]x=7x\frac{2}{35}[/tex]

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

1. The perimeter of a piece of paper is 18 cm.
a. List three different possible sets of dimensions for the paper, as well as the resulting areas.

Answers

Answer:

a) length = 3 and width = 6

Area of the rectangle = 3 × 6 = 18 cm²

b)  length = 7 and width = 2

Area of the rectangle = 7 × 2 = 14 cm²

c)  length = 5 and width = 4

Area of the rectangle = 5× 4 = 20 cm²

Step-by-step explanation:

Step(i):-

Given perimeter of the paper = 18 cm

we know that the paper has a rectangle shape

The perimeter of the rectangle = 18 cm

 2( l + w ) = 18

a)

we choose length = 3 and width = 6

The perimeter of the rectangle = 2( 3+6) = 18 cm

Area of the rectangle = 3 × 6 = 18 cm²

b)

we choose length = 7 and width = 2

The perimeter of the rectangle = 2( 7+2) = 18 cm

Area of the rectangle = 7 × 2 = 14 cm²

c)

we choose length = 5 and width = 4

The perimeter of the rectangle = 2( 5+4) = 18 cm

Area of the rectangle = 5× 4 = 20 cm²

Answers

answer:

yes, because they have a common difference and it makes sense. in order to determine if this is a function, you would have to find their difference for each column. the x column has a difference of 2 for all. similarily, the y column has a difference of 2 for all. therefore, it is a function.

Two trains, Train A and Train B, weigh a total of 381 tons. Train A is heavier than Train B.
The difference of their weights is 193 tons. What is the weight of each train?
I need this answer quick!

Answers

Answer:

Train A is 287 tons

Train B is 94 tons

Step-by-step explanation:

My method of solving it may have been a bit different from how you were taught. I divided 381 by 2 to give both trains an equal weight of 190.5 tons. I then divided the difference, 193, by 2 to get 96.5 tons. I subtracted the new difference from the weight of Train B and added it to train A. To double check, you can grab a calculator and see that their weights are equal to 381.

Steve is writing about this excerpt from The Jungle Book.

Akela raised his old head wearily:—

"Free People, and ye too, jackals of Shere Khan, for twelve seasons I have led ye to and from the kill, and in all that time not one has been trapped or maimed. Now I have missed my kill. Ye know how that plot was made. Ye know how ye brought me up to an untried buck to make my weakness known. It was cleverly done. Your right is to kill me here on the Council Rock now. Therefore I ask, 'Who comes to make an end of the Lone Wolf?' For it is my right, by the Law of the Jungle, that ye come one by one."

There was a long hush, for no single wolf cared to fight Akela to the death. Then Shere Khan roared: "Bah! What have we to do with this toothless fool? He is doomed to die! It is the man-cub who has lived too long. Free People, he was my meat from the first. Give him to me. I am weary of this man-wolf folly. He has troubled the jungle for ten seasons. Give me the man-cub, or I will hunt here always, and not give you one bone! He is a man—a man's child, and from the marrow of my bones I hate him!"



Steve makes the claim "Akela is willing to give his life for the Law of the Jungle.”

Which evidence from the text best supports this claim?

Akela is willing to die because he missed the kill.
Akela is willing to die because he is old and toothless.
Akela is willing to die because Shere Khan makes a better leader
Akela is willing to die because he was tricked.
