Answer:

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

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.

Step-by-step explanation:

tn=3n+8

t1=3*1+8

=3+8

=11

t7=3*7+8

=21+8

=29

t14=3*14+8

=42+8

=50

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:

answers below

Step-by-step explanation:

1.  21.50n (Print it)

2. 70+18n (Top Print)

3. This one is more complicated. First, you find out the cost from each store, by inserting 30 in place of n. (1. =645), (2.=610). Then, you subtract 610 from 645, which gets your difference to 35$.

4. There is an error in the wording, but the answer should be something along the lines of this. "Bill would need to buy 2 fewer shirts from Print It than from Top Print for Print it to be cheaper."

Answer:

Step-by-step explanation:

The daily tips were 743.36

8 people divided the money

Tips = 743.36 / 8 = 92.92

I can't explain how the others were obtained. The answer is A

Answer:

0.575 ounce

Step-by-step explanation:

Total paint

= Green paint + white paint

= 1.6 ounces + 1.85 ounces

= 3.45 ounces

Paint in each part if divided into 6 parts equally

= 3.45 ounces/6

= 345 ounces/600

= 23/40

= 0.575 ounce

The amount of green and white paint in each part is 0.27 ounces and 0.31 ounces respectively.

The ratio is the division of the two numbers.

Proportion is the relation of a variable with another. It could be direct or inverse.

Given that,

Amount of green paint = 1.6 ounces

Amount of white paint = 1.85 ounces

Total paint = 1.6 + 1.85 = 3.45

The ratio of green paint to total paint = 1.6/3.45 = 0.46

Now, this ratio must be maintained in each part after dividing it into 6 equal parts.

Total paint in each section after dividing = (1.6 + 1.85)/6 = 0.58

With the same ratio,

Green paint / Total paint = 0.46

Green paint / 0.58 = 0.46

Green paint  = 0.27 ounces

White paint = total paint - green paint

White paint = 0.58 - 0.27 = 0.31 ounces

Hence "The amount of green and white paint in each part is 0.27 ounces and 0.31 ounces respectively".

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

-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

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]

Answer:

-3

Step-by-step explanation:

A postive and a negative becomes a negative.

So -3 + - 6 becomes

-3 - 6

= -9

The -9 is over 3, which is 9/3 negated, so 3 negated which is -3.

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! : )

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
