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]
Choose 3 values that would make this inequality true. 12 57 +n
Answer:
8, 10, 5
Step-by-step explanation:
7+8=15, 7+10=17, 7+5=12. You’re basically substituting the numbers in for n and seeing if its greater than or equal to 12.
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!
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.
Answer:
║∦║∵·∵°∞∴·°∵Hello Person∵·°∴∵°∞°·║∦║

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.
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

Lucy cut 4 EQUIVALENT lengths of ribbon. Each was 5 eighths of a yard long. How many yards of ribbon did she cut? Express as MIXED number.
Answer:
yards.
Step-by-step explanation:
Please find the attachment.
We have been given that Marisela cut four equivalent lengths of ribbon. Each was 5 eighths of a yard long.
To find yards of ribbon cut by Marisela, we will multiply 4 by 5 eighths of a yard (5/8).
Express answer as the sum of whole number and the remaining fractional units:
Therefore, Marisela cut yards of ribbon.

i need help on the math question if it's right I'll give brain.
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]
what is 65% of 80 ??????????????
Answer:
Step-by-step explanation:
65% of 80 is
65*80/100=52
Answer:
52
Step-by-step explanation:
Calculate percentage:
'Percentage' is obtained by multiplying 80 by 65%.
65% × 80 =
(65 ÷ 100) × 80 =
(65 × 80) ÷ 100 =
5,200 ÷ 100 =
52
Checking:
How do we check the result?
If 65% × 80 = 52 =>
Divide 52 by 80...
... And see if we get as a result: 65%.
Calculate the percent value:
52 ÷ 80 =
0.65 =
0.65 × 100/100 =
(0.65 × 100)/100 =
65/100 =
65%

3x + 2y = -9
X – Y = -13
Answer:
x =-7. .y=6
Step-by-step explanation:
3x + 2y = -9
(X – Y = -13)×3
3x + 2y = -9
3x – 3y = -39
5y = 30
y=6
3x +2(6)=-9
3x=-21
x=-7
Is this a function even though there’s a -1 and a 1 in the same x column?
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.
