Answer:

Step-by-step explanation:

1).  91 + 41 + 53 + 54 {Simplify}

2).  138 + 53 + 54 {Simplify}

3).  191 + 54 {Simplify}

4).  245 {Add}

9514 1404 393

Answer:

  495

Step-by-step explanation:

There are several ways to figure this:

1) Multiply the average value by the number of numbers. The average number in an arithmetic sequence is the average of the first and last numbers in the sequence.

  average = (54+45)/2 = 49.5

  number of numbers = 54 -45 +1 = 10

  Total = 49.5 · 10 = 495

__

2) Add the numbers pairwise. It works best to work toward the middle from the ends:

  45 +54 = 99

  46 +53 = 99

  47 +52 = 99

  48 +51 = 99

  49 +50 = 99

  Total = 5 · 99 = 495

__

3) Subtract the sum of numbers to 44 from the sum of numbers to 54.

The sum of numbers 1 to n is (n)(n+1)/2.

  (54)(55)/2 -(44)(45)/2 = (27)(55) -(22)(45) = 1485 -990 = 495

__

4) Use a spreadsheet or calculator to add them. (see attached)

Answer: 16 feet is the width and 25 is length

Step-by-step explanation:

x*(2x-7)=400

Word problem written in numerical form^^^^

Solve for x to get 16

length = 2(16)-7= 25

Check our work

16*25=400 yay

hence, the common ratio of the given G.P. is 3 or −3.

Answer:

common ratio is -3 or 3

Step-by-step explanation:

[tex]u_1=1\\\\u_3=u_1*r^2=r^2\\\\u_5=u_1*r^4=r^4\\\\r^2+r^4=90\\\\r^4+r^2-90=0\\\Delta=1+4*90=361=19^2\\\\r^2=\dfrac{-1-19}{2} =-10 (exclude\ a\ square\ is\ positive)\\or\\r^2=\dfrac{-1+19}{2}=9\\r^2-9=0\\(r-3)(r+3)=0\\So\ r=-3\ or\ r=3\\[/tex]

Answer:

78

Step-by-step explanation:

26 + 26 + 26 = 78

Step-by-step explanation:

numbers

first = X

second = (x-10)

Third = 4(x-10)

x + (x-10) + 4(x-10) = 124

2x -10 + 4x-40 =124

6x - 50 = 124

6x = 124 + 50

6x = 174

x= 29

therefore the ;

first number = 29

second = (x-10) = 29-10 = 19

third= 4(x-10) = 4(29-10)= 76

Answer:

yes, you are telling right.

Answer: 4x² + 4xy - 3y²

Concept:

When encountering questions that ask for simplifying algebraic expressions, using the FOIL method would be easier:

Solve:

Given

(2x - y) (2x + 3y)

Expand parentheses and apply the FOIL method

=4x² + 6xy - 2xy - 3y²

Combine like terms

=4x² + (6xy - 2xy) - 3y²

=[tex]\boxed{4x^2+4xy-3y^2}[/tex]

Hope this helps!! :)

Please let me know if you have any questions

the answer is 47yd²

hope it help n please give me brain.. thanks

Answer:

Ok, so:

-The number of people who like tea are represented in the first column.

-The number of people who dislike tea are represented in the second column.

-The number of people who like coffee are represented in the first row.  

-The number of people who dislike coffee are represented in the second row.

This works like a multiplication chart:

People who like tea and coffee are represented in the top left square. People who dislike tea and coffee are represented in the box that coordinates to T' and C' (If you find T' and C' and run your fingers along the column/row until they run into each other, you'll find it.) The same is true for other combinations.

At the bottom of the first column is the total number of people who like tea. At the right-most part of the first row, is the total number of people who like coffee.

(52 people like tea, 80 people were surveyed)

I hope this helps you understand, please ask any clarifying questions you need! : )

Commutative Property of Addition

Step-by-step explanation:

3(x − 4) + 5x = 9x − 36

3x − 12 + 5x = 9x − 36  Distribute

3x + 5x − 12 = 9x − 36 Commutative Property of Addition

Step-by-step explanation:

-8

-9

-10

-11

just subtituted the remaining values of x.

Answer:

x= -1 —> y= –8

x=0 —> y= –9

x=1—> y= –10

x=2—>y= —11

Step-by-step explanation:

x= -1 —>y= -(-1)-9= +1-9 = –8

x=0 —> y= -(0)-9= –9

x=1—> y= -(1)-9= -1-9= –10

x=2—>y= -(2)-9 = —11

Step-by-step explanation:

add all number and simply divide it by 2

Answer:

13, 24, and 34

Step-by-step explanation:

0, 1, 1, 2, 3, 5, 8, 13, 24, 34, . . .

0+ 1 = 1

1+ 1 = 2

2+ 1 = 3

3+ 2 = 5

5+ 3 = 8

8+ 5 = 13

13+ 8 = 24

24+ 13 = 34

start at 1, then add the number behind it to move forward one space. repeat process.

Answer:

3.71 = (3.7 × 10)(1 × 10) = 3710.

Step-by-step explanation:

This fraction is alread reduced, We can't reduce it any further). As the numerator is greater than the denominator, we have an IMPROPER fraction, so we can also express it as a MIXED NUMBER, thus 3710 is also equal to 3710 when expressed as a mixed number.

Answer:

-1/2 , -1, -3/2

Step-by-step explanation:

1.)log base 16 1/4

log base 16 [tex]4 ^{-1 }[/tex] =x

[tex]16 ^{x} = 1/4[/tex]

x = -1/2

2.)log base 7 ¹/7

log base 7  [tex]7^{-1}[/tex] = x

7^x = 7^-1

x = -1

3.)log base 4 ⅛

4^x = 1/8

[tex]2^{2x} = 2^{-3}[/tex]

2x = -3

x = -3/2

Answer:

Step-by-step explanation:

1. Let a = log16 0.25, then:

0.25 = 16 ^ a = 16^-0.5

So the answer is -0.5.

2. log7 1/7

1/7 = 7^-1

Answer is -1.

3.  log4 1/8

1/8 = 4^(-1.5)

Answer is -1.5

Answer:

h=4.5

Step-by-step explanation:

15-2h=6   Get rid of any constants of the side of the variable.

-15    -15

-2h=-9      Divide -2 from both sides to isolate h.

/-2  /-2

h=4.5

Hope this helped you out! Have a wonderful day :)
