what is the correct answer​

Answer:

45231 = [tex]4 \times 10000 + 5\times 1000 +2 \times 100 + 3\times 10 +1 \times 1[/tex]

Step-by-step explanation:

Given the number:

45,231

We have To write the given number in the expanded form.

Solution:

First of all, let us write the different digits of the number:

Unit's digit = 1

Ten's digit = 3

Hundred's digit = 2

Thousand's digit = 5

Ten thousand's digit = 4

Unit's digit has to be multiplied with 1.

Ten's digit has to be multiplied with 10.

Hundred's digit has to be multiplied with 100.

Thousand's digit has to be multiplied with 1000.

Ten Thousand's digit has to be multiplied with 10000.

And then they have to be added so that the number gets formed.

45231 = [tex]4 \times 10000 + 5\times 1000 +2 \times 100 + 3\times 10 +1 \times 1[/tex]

Answer:

Option (2)

Step-by-step explanation:

If m(x) and n(x) are the functions inverse of each other,

Then the following condition should be fulfilled,

m[n(x)] = n[m(x)] = x

Here, m(x) = [tex]\frac{3x}{x+7}[/tex] and n(x) = [tex]\frac{7x}{3-x}[/tex]

m[n(x)] = [tex]\frac{3(\frac{7x}{3-x})}{(\frac{7x}{3-x})+7}[/tex]

          = [tex]\frac{21x}{7x+21-7x}[/tex]

          = x

n[m(x)] = [tex]\frac{7(\frac{3x}{x+7})}{3-\frac{3x}{x+7}}[/tex]

           = [tex]\frac{21x}{3x+21-3x}[/tex]

           = x

Therefore, [tex]\frac{3(\frac{7x}{3-x})}{(\frac{7x}{3-x})+7}=\frac{7(\frac{3x}{x+7})}{3-\frac{3x}{x+7}}=x[/tex] will be the correct option.

Option (2) will be the answer.

Answer:

Explained below.

Step-by-step explanation:

The value of different types of coins are as follows:

1 penny (p) = 1 cent

1 nickel (n) = 5 cents

1 dime (d) = 10 cents

1 quarter (q) = 25 cents

It is provided that Taylor has 18 cents in dimes and nickels in her pocket.

This is not possible.

Because the sum of any number of dime and nickel coins will always be a multiple of 5.

a·d + b·n = 10a + 5b = 5 (2a + b)

The value 18 cents can be formed as follows:

8p + d = 18 cents

3p + n + d = 18 cents

3n + 3p = 18 cents

Step-by-step explanation:

Graph the systems of equations. Then analyze the graph for the intersection. The point of intersection will be your solution set.

Answer:

[tex]x = -2\\y = -4[/tex]

Step-by-step explanation:

Question

[tex]\left \{ {{-2x + 2y = -4} \atop {3x + 3y = -18}} \right.[/tex]

Multiply throughout the equation to eliminate a variable:

[tex]-2x + 2y = -4[/tex] becomes [tex]-6x + 6y = -12[/tex] when multiplied by 3

[tex]3x + 3y = -18[/tex] becomes [tex]6x + 6y = -36[/tex] when multiplied by 2

Then add the values of the variables together:

[tex]-6x + 6x = 0\\6y + 6y = 12y \\-12 - 36 = -48[/tex]

And a new equation forms:

[tex]0 + 12y = -48[/tex]

[tex]y = -4[/tex]

Plug in [tex]y[/tex] to any of the previous equations to solve for [tex]x[/tex] :

[tex]-2x + 2y = -4[/tex]

[tex]-2x + 2(-4) = -4[/tex]

[tex]-2x - 8 = -4[/tex]

[tex]-2x = 4[/tex]

[tex]x = -2[/tex]

You can use the commutative property to rearrange the problem like this, 18 + 28 * 28 * 28 * 28 = 130

Basically, you can use the properties of operations to solve 18 + 4(28) in various ways. Though whichever operation you apply must give you the same result. The result of 18 + 4(28) is 130.

   The four basic types of properties of operations are commutative, associative, distributive and identity. These properties only apply to the operations of addition and multiplication.

   According to the purplemath site, "The word 'commutative' comes from 'commute' or 'move around', so the Commutative Property is the one that refers to moving stuff around. For addition, the rule is 'a + b = b + a'; in numbers, this means 2 + 3 = 3 + 2. For multiplication, the rule is 'ab = ba'; in numbers, this means 2×3 = 3×2."

   According to the splashlearn site, "the associative property of addition, the sum of three or more numbers remains the same regardless of how the numbers are grouped. Here's an example of how the sum does NOT change irrespective of how the addends are grouped. Here's another example. ( 75 + 81 ) + 34."

   According to the mathwarehouse site, "In general, this term refers to the distributive property of multiplication which states that the. Definition: The distributive property lets you multiply a sum by multiplying each addend separately and then add the products."

   According to the math site, "Identity property. The identity property for addition tells us that zero added to any number is the number itself. Zero is called the 'additive identity.' The identity property for multiplication tells us that the number 1 multiplied times any number gives the number itself."

Answer:

Sample response: Use the distributive property and expand 28, then distribute the 4 to 20 and the 4 to 8. Then you have 18 + 80 + 32. Use commutative property to reverse the order of 32 and 80 so that 18 and 32 are friendly numbers to add.

Step-by-step explanationWhich reasons did you include in your response? Check all that apply.

The distributive property can be applied to multiply 4(28) mentally.

The number 28 can be expanded to 20 + 8.

The commutative property can be applied to reverse the order of numbers.:

Answer:

m = 3/40

Step-by-step explanation:

4 = 3/4m - 6

m*4 = m(3/4m -6)

4m = m*3/4m + m*-6

4m = 3/4 - 6m

6m + 4m = 3/4

10m = 3/4

m = (3/4)/10

m = 3/40

check:

4 = 3/(4*3/40) - 6

4 = 3/(12/40) - 6

4 = (3*40)/12 - 6

4 = 120/12 - 6

4 = 10 - 6

Answer:

45

Step-by-step explanation:

So we have the expression:

[tex]ab^2-d[/tex]

And we want to evaluate it for a=3/4, =-8, and d=3.

Thus, substitute in these values:

[tex]=(\frac{3}{4})(-8)^2-3[/tex]

Do the exponent first. -8 squared is positive 64:

[tex]=(\frac{3}{4})(64)-3[/tex]

And 3/4 times 64 is 48:

[tex]=(48)-3[/tex]

Subtract:

[tex]=45[/tex]

Answer:

5y = -5

Step-by-step explanation:

-2(3y+5)= -4

Divide each side by -2

-2/ -2  (3y+5)= -4/-2

3y+5 = 2

Subtract 5 from each side

3y +5 -5 = 2-5

3y = -3

Divide by 3

3y/3 = -3/3

y = -1

5y = 5*-1 = -5

Answer:

Step-by-step explanation:

Perimeter of a rectangle = 2l + 2w

where

l is the length

w is the width

From the question

Perimeter = 578 yds

The statement

The length is one more than three times the width is written as

l = 1 + 3w

Substitute the expression into the above formula and solve for the width

That's

578 = 2(1 + 3w) + 2w

578 = 2 + 6w + 2w

8w = 576

Divide both sides by 8

w = 72

Substitute w = 72 into l = 1 + 3w

That's

l = 1 + 3(72)

l = 216 + 1

l = 217

Therefore the dimensions are

length = 217 yd

width = 72 yd

Hope this helps you

Answer:

Step-by-step explanation:

Let a, b, c represent the amounts received by the first, second, and third person, respectively.

  2a-1 = b

  c = b+11

  a + b + c = 224

Substituting for c, we have ...

  a + b + b+11 = 224

  a +2b = 213

Substituting for b, we have ...

  a +2(2a -1) = 213

  a +4a -2 = 213 . . . . . eliminate parentheses

  5a = 215 . . . . . . . . . . add 2

Step-by-step explanation:

Sharonda is plotting quadrilateral PQRS on the graph below She will plot the fourth and final vertex, S, at (9, 5), the length of side PS will be 11 units.

A quadrilateral is a four-sided polygon. The sum of the interior angles of a quadrilateral is always equal to 360 degrees. There are several types of quadrilaterals, including: Square, rectangle, parallelogram, rhombus, trapezoid, and kite.

Length of side PS can be calculated using the distance formula,

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Where,

P(-2, 5) = ([tex]x_1,y_1[/tex]) (the coordinate of P is gotten from the graph).

Given that,

S(9, 5) = ([tex]x_2,y_2[/tex])

PS = [tex]\sqrt{(9-(-2))^2+(5-5)^2}[/tex]

PS = [tex]\sqrt{11^2+0^2}[/tex]

PS = [tex]\sqrt{121}[/tex]

PS = 11units.

Thus, the answer is 11 units.

Answer:

When factorizing one number, what you get are other numbers that, when they get multiplied, the result of the product is the first number.

In our case, the pair of 3, 12 and the pair of 4, 9 are factors of 36, as it's the number we get when multiplying them:

We can factroize 36 like this: 2*2*3*3, and:

The factor pairs belong to the number 36.

The breaking or decomposition of an entity (such as a number, a matrix, or a polynomial) into a product of another entity, or factors, whose multiplication results in the original number, matrix, etc., is known as factorization or factoring in mathematics.

As per the given data:

The factor pairs are as follows:

3, 12

4, 9

We have to find out that of which number these factor pair belongs.

When the factors of any number are multiplied with each other, we get that number.

For finding out the number, we need to multiply the factor pairs:

3 × 12 = 36

4 × 9 = 36

The factor pairs belong to the number 36.

Hence, The factor pairs belong to the number 36.
