[tex]\sf 3x-\left(2x-1\right)=7x-\left(3\times \:5x\right)+\left(-x+24\right)[/tex]

Remove the parentheses:

[tex]\to\sf 3x-\left(2x-1\right)=7x-3\times \:5x-x+24[/tex]

Combine like terms:

[tex]\sf ^*7x-x=6x[/tex]

[tex]\to\sf 3x-\left(2x-1\right)=6x-3\times \:5x+24[/tex]

Multiply 3 and 5x = 15x:-

[tex]\to\sf 3x-\left(2x-1\right)=6x-15x+24[/tex]

Combine like terms:

[tex]\sf ^*6x-15x=-9x[/tex]

[tex]\to\sf 3x-\left(2x-1\right)=-9x+24[/tex]

Expand: 3x-(2x-1)= x+1

[tex]\to\sf x+1=-9x+24[/tex]

Subtract 1 from both sides:

[tex]\to\sf x+1-1=-9x+24-1[/tex]

[tex]\to\sf x=-9x+23[/tex]

Add 9x to both sides:

[tex]\to\sf x+9x=-9x+23+9x[/tex]

[tex]\to\sf 10x=23[/tex]

Divide both sides by 10:

[tex]\to\sf \cfrac{10x}{10}=\cfrac{23}{10}[/tex]

[tex]\to\sf x=\cfrac{23}{10}[/tex]

Given set is A = {x:x+3 = 3 and x € N }

A is an empty set .

Reason :-

Put x = 1 then x+3 = 1+3 = 4

Put x = 2 then x+3 = 2+3 = 5

If we put x = 1,2,3...

We get { 4,5,6...}

So there is no natural number for x to get x+3 = 3

So ,There is no element to write for the set A

A is an empty set .

Note :-If x€W then x+3 = 0+3 = 3 then A is not an empty set .

Answer:

533.15

Step-by-step explanation:

$15*19.85+3*5.62+7*31.22

=533.15

Make me brainliest

The best estimate in dollars for the classroom items will be equal to $533.15.

The four fundamental operations of arithmetic are addition, subtraction, multiplication, and division of two or even more items.

Included in them is the study of integers, especially the order of operations, which is important for all other areas of mathematics, notably algebra, data management, and geometry.

As per the data given in the question,

Total pencil boxes = 15

Price of each pencil box = is $19.85

Then, the price of 7 pencil boxes will be: 15 × $19.85 = $297.75

Total Erasers boxes = 3

Price of each eraser box = is $5.62

Then, the price of 3 eraser boxes will be: 3 × $5.62 = $16.86

Total dry-erase boxes = 7

Then, the price of 7 dry-erase boxes will be: 7 × $31.22 = $218.54

Then, the total price of all these items will be,

$297.75 + $16.86 + $218.54 = $533.15

The required product of the given expression is given as -2/25a³b² + 2/15ab + 7/180abcd.

Given that,
To find the products [1/5a²/b - 1/3c] × [-2/5ab - 1/6cd].

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,

Here,
Given expression,
= [1/5a²/b - 1/3c] × [-2/5ab - 1/6cd]
= 1/5a²/b[-2/5ab - 1/6cd]  - 1/3[-2/5ab - 1/6cd]
= -2/25a³b² - 1/60abcd +2/15ab + 1/18abcd
= -2/25a³b² + 2/15ab + 7/180abcd

Thus, the required product of the given expression is given as -2/25a³b² + 2/15ab + 7/180abcd.

Answer:

Step-by-step explanation:

46 feet

The New perimeter of Brandy deck is 46 feet .

The entire length of all the sides of a rectangle is called the perimeter. As a result, we can calculate the perimeter of a rectangle by adding all four sides.

Using the given information,

Width = 7 Feet

Length = 12 feet

Perimeter = 2 (Width + Length)

                 = 2(7+12)

                 =2(19)

                 =38

Perimeter when deck is 4 feet longer =  38 + 4+4=46 Feet

Hence, the  new perimeter of a deck is 46 feet.

Answer:

A - 17,400

B - 627,120

Step-by-step explanation:

A.) A house that has a value of $29,000 is being depreciated(value is being lowered) 10% each year for 4 years. So after 4 years is will be depreciated by 40%

40% of 29,000 is 11,600

29,000 - 11,600 = 17,400

B.) A house that has a value of $435,500 is being appreciated(value is being raised) by 4%. So in the next 11 years it will be appreciated by 44%.

44% of 435,500 is 191,620

435,500 + 191,620 = 627,120
