Answers

Answer 1

Answer:

the answer is x8

Step-by-step explanation:

the answer is x8

Answer 2

Answer:

y = -2x

Step-by-step explanation:

The appropriate "direct variation" rule (formula) is y = kx.

Since y = 4 when x = -2, 4 = k(-2), or k = -2

Then the specific formula relating x and y is y = -2x

The numbers 541A3, 541B3, and 541C3 are all different multiples of 3. The letters A, B, and C represent digits within the number. What is the product A times B times C?

Answers

Answer:

80

Step-by-step explanation:

541A3 is a multiple of 3 when the sum of the digit is a multiple of 3 so the sum of the 4 given number is 5+4+1+3=13. but we need it to be a multiple of 3 so we add 2 so A is 2. Using similar logic B=5 and C=8 so the product of A B and C is 2*5*8=80

What are arithmetic Operations?

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

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 .

brandy has a rectangular wooden deck that measures 7 feet by 12 feet. She build an addition to the deck that is 4 feet longer. What is the Perimeter of her deck now

Answers

Answer:

Step-by-step explanation:

46 feet

The New perimeter of Brandy deck is 46 feet .

Perimeter of a rectangle

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.

How can we find new perimeter of a deck?

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.

PLEASEE SOMEONE ANSWER THIS PLSSSSSS

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

Answers

Answer:

x = 3/4

Step-by-step explanation:

1. Rearrange terms

2x - 1 = 5 - 6x

2x - 1 = -6x + 5

2. Add 1 to both sides of the equation. We want to get rid of -1.

2x -1 = -6x + 5

    +1            +1

-------------------------

2x = -6x + 6

3. Simplify.

2x + 6x = 6

8x = 6

6/8 = 3/4

Then, the answer is 3/4.
