3(2y + 3) + y

Answers

Answer:

 7y + 9

   

Step-by-step explanation:

Given expression:

     3(2y + 3) + y;

  To solve this problem, apply PEMDAS;

P   = parentheses

E    = exponent

M   = multiplication

D    = division

A     = addition

S      = subtraction

   3(2y + 3) + y;

 Start solving from the parentheses by applying the distributive property;

  6y + 9 + y

  =  7y + 9

Step 2: Collect any like terms on both sides of the equation. (2 points)


Step 3: Bring all variable terms to one side of the equation. (Hint: Add x to both sides.) (2 points)

Answers

Answer:

x=-3

Step-by-step explanation:

5(x - 4) + 3x - 9x = 6 - (2x + 5) + 8x

(remove parentheses)

5x-20+3x-9x=6-2x-5+8x

(collect like terms and calculate)

-x-20=1+6x

(move the terms)

-x-6x=1+20

(collect like terms and calculate)

-7x=21

(divide both sides)

x=-3

Find the perimeter of the figure.
7 mi
7 mi

Answers

Answer:

28mi

Step-by-step explanation:

The perimeter of a figure is the total length of its outline, so a sum of all its lengths.

In the diagram we are given two of them, both 7, but not the other two.

Luckily these can be easily worked out.

Since this is a square figure (all angles 90-degrees), all parallel sides will be exactly equal in length. This means both of the unknown sides are 7mi long as well. This means the total perimeter is the sum of all four sides, each of which are 7mi.

7+7+7+7 (OR 4x7) = 28 mi

Hope this helped!

Answer:

The perimeter of the figure is 28 mi

Step-by-step explanation:

Perimeter of a Square

Given a square shape of side length A, the perimeter can be found using the expression below:

P = 4*A

Recall the perimeter is the sum of all the side lengths.

Since the figure shows a square with side length A=7 mi, the perimeter is:

P = 4 * 7 mi = 28 mi

The perimeter of the figure is 28 mi

5) Kareem Abdul-Jabbar holds the NBA record for the most points scored in a
career, 38,387. In the first 280games of his career, LeBron James has scored 7446
points. At this rate, how many more games willLeBron James need to play to
break Abdul-Jabbar's career record?

Answers

Answer:

Step-by-step explanation:

LeBron James need to play to 1444 games to break Abdul-Jabbar's career record.

What is rate of change?

A rate of change is a rate that describes how one quantity changes in relation to other.

Given world record Kareem Abdul-Jabbar = 38,387 points.

Games played by LeBron = 280 games

Score of LeBron = 7446 points

Hence for each point LeBron has to play = 280/7446 games

Therefore to break the world record number of games required

                                       = (280*38,387)/7446

number of games required = 1443.5

or, number of games required = 1444

Hence,at this rate LeBron James need to play to 1444 games to break Abdul-Jabbar's career record.

Tabithas living room is rectangle that measures 19 3/4ft by 12ft find the perimeter and the area of the room

Answers

Answer:

237ft²

63.5ft

Step-by-step explanation:

Given parameters:

  Length  = 19[tex]\frac{3}{4}[/tex] ft

   Width  = 12ft

Unknown:

Area of rectangle  = ?

Perimeter of rectangle  = ?

Solution:

Area of rectangle  = length x width

                              = 19[tex]\frac{3}{4}[/tex] x 12

                               = [tex]\frac{79}{4}[/tex] x 12

                               = 79 x 3

                              = 237ft²

Perimeter of rectangle  = 2(length + width)

                                      = 2 (19.75 + 12 )

                                     = 63.5ft

how to factor g2 − 32g + 256

Answers

Answer:

Using the snowflake method, you have to find the factors of 256 that add up to get 32.

The result will look like this:

(g-16)(g-16)

Answer:

[tex](g-16)^2[/tex]

Step-by-step explanation:

[tex]g^2-32g + 256[/tex]

To factor it you should remember that

[tex](a-b)^2 = a^2 -2ab+b^2[/tex]

It is easy to seee that

[tex]32 = 2 \cdot 16[/tex]

and

[tex]256 = 16^2[/tex]

Therefore

[tex]g^2-32g + 256 = g^2 - (2\cdot 16)g+ 16^2 = (g-16)^2[/tex]

Step-by-step explanation:

an inspector tested the first 125 radios that came off the production line today and found only 60% acceptable. After the inspector tested 25 more radios, the overall percentage of acceptable radios rose to 62%. The number of these 25 radios that were rejected is???

Answers

Answer: 7 radios

Step-by-step explanation:

The following can be deduced from the question:

Number of radios tested = 125 radios

Percentage acceptable = 60%

Numbers acceptable:

= 60% × 125

= 0.6 × 125

= 75 radios

Numbers rejected = 125 - 75 = 50 radio

We are further told that the inspector tested 25 more radios, this will be:

Number of radios tested

= 125 + 25 = 150 radios

Percentage acceptable = 62%

Numbers acceptable

= 62% × 150

= 0.62 × 150

= 93 radios

Numbers rejected= 150 - 93 = 57 radios

The number of these 25 radios that were rejected will be:

= 57 - 50

= 7 radios
