281.25-5.25a=2.75

step by step:

so you divide the total amount by two and you get 140.62

then you divide that by 5.25 and you get 26.78

plug that into a and you get 140.62

then you take the remainder which is 140.62 and you divide that by 2.75

which is 51.13 and that will be your number for s

and at the end you should get the remainder of 140.62

then you multiply 140.62 by 2 and you get were you started and thats how you check your answer

Answer:

All parallelograms are trapezoids.

Step-by-step explanation:

A parallelogram has two pairs of parallel sides. A trapezoid has at least one pair of parallel sides. So if all parallelograms have two pairs, they are in the same category of the trapezoids.

Final answer:

A parallelogram is considered a trapezoid because it has at least one pair of parallel sides, which fits the basic definition of a trapezoid. Parallelograms have additional properties like equal opposite sides and angles, but these do not contradict the broader trapezoid classification.

Explanation:

Why All Parallelograms Are Trapezoids

A trapezoid is defined as a quadrilateral with at least one pair of parallel sides. A parallelogram, by definition, has two pairs of parallel sides. Therefore, since a parallelogram inherently possesses at least one pair of parallel sides, it meets the minimum criterion to be considered a trapezoid. This logical inclusion is based on the definition of shapes within geometry, and thus all parallelograms can be classified as trapezoids.

Properties of Parallelograms and Trapezoids

Parallelograms have some additional properties that trapezoids don't necessarily share, such as opposite sides being equal in length and opposite angles being equal. This does not, however, preclude them from the broader categorization of trapezoids because those extra properties do not contradict the definition of a trapezoid.

Applying similar triangles and their properties, although useful for understanding relationships between different shapes, is not directly necessary for explaining why parallelograms are trapezoids. Instead, it's the fundamental definitions of these shapes that establish the relationship between parallelograms and trapezoids. The Theorem 26 states that any triangle is always of equal area to a certain parallelogram having an equal base and half the altitude. While this theorem relates parallelograms to triangles, it does not affect the classification of parallelograms as trapezoids.

Answer:

The required way is shown above.

Step-by-step explanation:

Consider the provided calculation.

304 – 81 is very close to 304 – 100,

Now subtract 100 from 304 mentally, it will gives us 204

Now add 19 as we round 81 to 100.

204 + 19 = 223

So, the answer is 223.

Now write a coherent sequence of equations that correspond to your reasoning.

304 – 81  =  304 – (100 – 19)

                = (304 – 100) + 19  

                =  204 + 19  =  223

Hence, the required way is shown above.

To subtract 81 from 304 mentally, round 81 to 80, subtract from 304 to get 224, and then add 1 to compensate for the rounding, giving a final answer of 225.

To calculate 304-81 mentally, we can use the strategy of rounding and compensating. First, we can round 81 up to a number that is easier to subtract from 304, such as 80 or 100, and then we adjust the final result to account for the rounding. Here's how to think through it:

The coherent sequence of equations that correspond to this reasoning would be:

This mental math strategy involves rounding and compensation, which allows us to handle subtraction problems quickly without having to use the standard subtraction algorithm. Checking that the answer makes sense in the context of the original problem is a good practice to ensure accuracy.

Final answer:

The degree of the polynomial 5a⁶bc²+8d⁵+7e⁶f²-10g⁴h⁷ is 11, determined by the highest sum of exponents in any term of the polynomial, which is found in the term -10g⁴h⁷.

Explanation:

The degree of a polynomial is the highest exponent of its variables when it is expressed in standard form. To find the degree of the given polynomial 5a⁶bc²+8d⁵+7e⁶f²-10g⁴h⁷, we look at each term individually and sum the exponents of the variables within that term. The terms of the polynomial are:

5a⁶bc² with a degree of 6 + 1 + 2 = 9

8d⁵ with a degree of 5

7e⁶f² with a degree of 6 + 2 = 8

-10g⁴h⁷ with a degree of 4 + 7 = 11

Comparing the sums of the exponents, we see that the term -10g⁴h⁷ has the highest sum which is 11. Therefore, the degree of the given polynomial is 11.

Answer:

The number is 4

Step-by-step explanation:

* Lets revise some words in mathematics and how change them to

 mathematical symbols

- More than ⇒ add (+)

- Less than ⇒ subtract (-)

- Twice ⇒ Multiplied by 2 (× 2)

- Opposite of a number ⇒ change its sign (additive inverse of it)

* Now lets solve the problem

- Nine more than the opposite of a number is three less than twice

 the number

- Assume that the number is x

∴ 9 more than the opposite of x

- That means find the opposite of x and add it by 9

∵ The opposite of x is -x

∴ Nine more than the opposite of a number = -x + 9

- Three less than twice the number means 3 less than twice x

∵ The number is x

∴ Twice the number = 2 × x = 2x

∵ Three less than twice x = 2x - 3

∴ Three less than twice the number = 2x - 3

- The meaning of "is" between the two the statements is "="

∴ Nine more than the opposite of a number is three less than twice

  the number is ⇒ -x + 9 = 2x - 3

* Lets solve the equation to find x

∵ -x + 9 = 2x - 3

- add x in both sides

∴ 9 = 3x - 3

- Add 3 to both sides

∴ 12 = 3x

- Divide both sides by 3

∴ x = 4

∵ x represents the number

∴ The number is 4

* Lets check the answer

9 more than opposite 4 is 3 less than twice 4

9 + (-4) = 2 × 4 - 3

9 - 4 = 8 - 3

5 = 5

The answer is right

Answer:

x=-81

Step-by-step explanation:

Multiply both sides of the equation by 3 to eliminate the fraction on the left side.

[tex]-x/3(3)=27(3)[/tex]

[tex]-x=81[/tex]

Divide both sides by -1 to isolate x on the left side of the equation

[tex]-x/-1=81/-1\\x=-81\\[/tex]

Answer:

x = - 81.

Step-by-step explanation:

Given  : [tex]\frac{-x}{3} = 27[/tex].

To find : solve the equation.

Solution: We have given

[tex]\frac{-x}{3} = 27[/tex].

On multiplying both sides by 3

-x = 27*3.

On dividing both sides by -1.

x = - 81.

Therefore, x = - 81.

Answer:Width = 15 units .

Step-by-step explanation:

Given  : The width of a rectangle is 4 more than half the length. If the perimeter of the rectangle is 74,

To find : what is the width.

Solution : We have given perimeter of the rectangle is 74,

Let the Length = x .

According to question :

The width of a rectangle is 4 more than half the length.

Width = 4 + [tex]\frac{x}{2}[/tex].

Perimeter = 2 length + 2 width .

Plugging the values,

74 = 2 ( x ) + 2 (4+[tex]\frac{x}{2}[/tex]).

74 = 2x + 8 + x .

Combine like terms

74 = 2x +x + 8.

74 = 3x +8.

On subtracting both sides by 8.

74 -8= 3x .

66 = 3x

On dividing both sides by 3

x = 22.

Width = Width = 4 + [tex]\frac{22}{2}[/tex].

Width = 4 +11.

Width = 15 units .

Therefore, Width = 15 units .

# Parenthesis

# Exponents

# Multiplication and Division which comes first from left to right

# Addition and Subtraction which comes first from left to right

- There is a word made from the first letter of each operation

  PEMDAS to remember the order of operations

* Lets solve the problem

# Expression: 1

∵ 9(2 + 7 f)

- To simplify this expression multiply the bracket by 9

∵ 9(2 + 7 f) = 9 × 2 + 7 f × 9

∵ 9 × 2 = 18

∵ 7 f × 9 = 63 f

∴ 9(2 + 7 f) = 18 + 63 f

* Expression: 1 ⇒ 18 + 63 f

# Expression: 2

∵ 6 × 7 - 3² × 9 + 4³

- At first simplify exponent

∵ 3² = 9 and 4³ = 64

∴ 6 × 7 - 3² × 9 + 4³ = 6 × 7 - 9 × 9 + 64

- Solve the multiplication first

∵ 6 × 7 = 42

∵ 9 × 9 = 81

∴ 6 × 7 - 3² × 9 + 4³ = 42 - 81 + 64

- Solve 42 - 81 first because it comes first from left to right

∵ 42 - 81 = - 39

∴ 6 × 7 - 3² × 9 + 4³ = - 39 + 64

- Add them

∵ - 39 + 64 = 25

∴ 6 × 7 - 3² × 9 + 4³ = 25

* Expression: 2 ⇒ 25

f(x) = 10x – 4  

10x = f(x)+4

x = f(x)/10 + 2/5

the inverse is y = x/10 + 2/5

The two numbers are 3 and -5. Let's start with 3. To get three, add 4 to -1. That means, going 4 to the right on a number line. When you do so, you will end up with 3. Since adding always go up.

Let's move onto -5 now. For this, go 4 to the left. Subtracting from negative numbers will be negative numbers. Since subtracting is going down, you go down on the number line.

Therefore, 3 and -5 is the answer!

Explaining channel:

Type HWsolver-Brainly. It should pop up at the bottom with a person thumbs up.

The two numbers that are 4 units away from -1 are -5 and 3.

In math, a number line can be defined as a straight line with numbers placed at equal intervals or segments along its length.

Now the given integer is, -1.

To find the numbers that are 4 units away we need to subtract and add 4 to get the required number.

So, 4 units forward from -1 is,

-1 + 4 = 3

And 4 units backward from -1 is,

-1 - 4 = -5

So the two numbers we get are 3 and -5.

Thus, the two numbers that are 4 units away from -1 are -5 and 3.

y: Represents the exponent of base 10

So, considering a system of equations we have:

[tex]x * 10 ^ y = 40,000\\\frac {x} {10 ^ y} = 0.000004[/tex]

From the first equation we have:

[tex]10 ^ y = \frac {40,000} {x}[/tex]

Substituting in the second equation:

[tex]\frac {x} {\frac {40,000} {x}} = 0.000004\\\frac {x ^ 2} {40,000} = 0.000004\\x ^ 2 = 40,000 * 0.000004\\x ^ 2 = 0.16\\x = \pm \sqrt {0.16}[/tex]

We choose the positive value:
