3x - x + 3 + x - 5 - x = x + 10

Answer:

A

Step-by-step explanation:

You can write an expression to represent the total cost of a pair of shoes. The price of the shoes is the variable r. The shoes are marked down 20% or 0.2r. So the new price of the shoes will be r - 0.2r. You will also have to pay a tax of 5% or 0.05 of the new price. This is written as 1.05(r - 0.2r). You can simplify it by doing whats in the parenthesis.

1.05(r - 0.2r) = 1.05r(0.8r) = 0.84r

Answer: $682.50

Step-by-step explanation:

The cost for Stefan’s insurance is determined by the row of data for a 36 year old male. A 10-year policy has a cost of $4.55 per thousand dollars of coverage. In order to determine the total cost you need to determine the amount of thousands of coverage, which is $150,000/1,000 = 150. The total annual cost is 150 x $4.55 = $682.50.

Answer:

The length of the rectangle is [tex]9\ cm[/tex]

Step-by-step explanation:

we know that

The area of rectangle is equal to

[tex]A=LW[/tex]

In this problem we have

[tex]A=27\ cm^{2}[/tex]

so

[tex]27=LW[/tex] ------> equation A

and

[tex]A=2w^{2}+3w[/tex]

so

[tex]27=2w^{2}+3w[/tex]

[tex]2w^{2}+3w-27=0[/tex]

The formula to solve a quadratic equation of the form [tex]ax^{2} +bx+c=0[/tex] is equal to

[tex]x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}[/tex]

in this problem we have

[tex]2w^{2}+3w-27=0[/tex]

so

[tex]a=2\\b=3\\c=-27[/tex]

substitute in the formula

[tex]w=\frac{-3(+/-)\sqrt{3^{2}-4(2)(-27)}} {2(2)}[/tex]

[tex]w=\frac{-3(+/-)\sqrt{225}} {4}[/tex]

[tex]w=\frac{-3(+/-)15} {4}[/tex]

[tex]w=\frac{-3(+)15} {4}=3[/tex]

[tex]w=\frac{-3(-)15} {4}=-4.5[/tex]

The solution of the quadratic equation is

[tex]w= 3\ cm[/tex]

Find the value of L

[tex]27=L(3)[/tex]

[tex]L=27/3=9\ cm[/tex]

Answer:

x-value is 4

Step-by-step explanation:

2x-3y=-1

3x+4y=24

We can solve the equation by eliminating y

We multiply the first equation by 4 and the second by 3

4(2x-3y=-1 )

3(3x+4y=24)

8x -12y = -4

9x +12y = 72

Then we add the two equations;

8x -12y = -4

9x +12y = 72

17x = 68

  x = 4

Thus the x-value is 4

Answer:

I wanna say that the answer is D p(x) = 8x + 20

Step-by-step explanation:

Answer; Carlos would be 72 inches tall

Step-by-step explanation:

because 1 foot = 12 inches . and he is 6 feet tall so 12 x 6 = 72 !

Hey there!

All we need to do is multiply 6 by 12

6 * 12 = 72

Therefore, Carlos is 72 inches tall

Step-by-step explanation:

Create an equation such that x equals the decimal number.

Count the number of decimal places, y. Create a second equation multiplying both sides of the first equation by 10y.

Subtract the second equation from the first equation.

Solve for x.

Reduce the fraction.

answer B. ( -infinity, +infinity)

Answer:

The correct answer option is B.

Step-by-step explanation:

We are to determine whether which of the given data sets in the answer options are continuous.

For this, we need to know what a continuous data set is.

A data set which have no definite end to its value but keep on continuing.

Here, the data sets given in A, C, D and E have definite starting and ending points.

While B is a continuous set as its values are continuing to infinity.

Answer:

A=4, B=3/4

Step-by-step explanation:

it says that she has four suit jackets, and since there are 16 possibilities(4 x 4)

and 4 of them have the same colors, we do 16-4/16, which is 12/16, and we simplify that to 3/4

Final answer:

Adrell has 16 different jacket/shirt outfits and there is a 75% probability that the jacket and shirt will not be the same color.

Explanation:

Adrell has four suit jackets (white, blue, green, and tan) and four dress shirts in the same colors. To find the number of different jacket/shirt outfits, we multiply the number of options for the jacket by the number of options for the shirt. Since there are 4 options for the jacket and 4 options for the shirt, there are a total of 16 different jacket/shirt outfits.

If Adrell grabs a suit jacket and a dress shirt without looking, the probability that they will not be the same color can be found by calculating the number of favorable outcomes (jacket and shirt of different colors) divided by the total number of possible outcomes. Since there are 4 jackets and 4 shirts, the total number of possible outcomes is 4 * 4 = 16. The number of favorable outcomes is when the jacket and shirt are of different colors, which is 4 * 3 = 12. Therefore, the probability that the jacket and shirt will not be the same color is 12/16 = 3/4 or 75%.

Answer:

The two types of income are - salary and commission.

Step-by-step explanation:

The two types of income that someone in a full-time sales job usually receives is a salary and commission.

The salary is the base pay that one receives regardless of the sales target they have.

The commission is that extra money that is also called incentive. This is based on the number of items you sell.

The commission can be overall increase in the pay or per item sales based.

Therefore, these two things generate the total income paid to a sales person.

Answer: square root of 3/2 seconds

Step-by-step explanation:

h=-16x²+24

Set the height to be 0

0=-16x²+24

-24=-16x²

24=16x²

24/16=x²

x²=3/2

x= square root of 3/2

you have to set the equation equal to 0 to represent when it hits the ground

0=-16x²+24

-24=-16x²

-24/16=x² --> -3/2=x²

x=-1.22474

The Answer is A. 3y=2

Step-by-step explanation:

1) combine like terms

7y + 7 = 9 + 2y + 2y

7y +7 = 9 + 4y

Subtract 4y on both sides

3y +7 = 9

Subtract 7 on both sides

3y = 2 because 9 - 7 = 2

Answer:

Polygon q’s area is one fourth of polygon p’s area

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its areas is equal to the scale factor squared

Let

z-----> the scale factor

x-----> polygon q’s area

y-----> polygon p’s area

so

[tex]z^{2} =\frac{x}{y}[/tex]

In this problem we have

[tex]z=\frac{1}{2}[/tex]

substitute

[tex](\frac{1}{2})^{2} =\frac{x}{y}[/tex]

[tex](\frac{1}{4}) =\frac{x}{y}[/tex]

[tex]x=\frac{1}{4}y[/tex]

therefore

Polygon q’s area is one fourth of polygon p’s area

Answer:

1/4 the area

commutative prop of multiplication

The equation 6*1=6 is an illustration of the Identity Property of Multiplication which states that any number multiplied by 1 yields the original number.

The question is asking about the mathematical property illustrated by the equation 6*1=6. In this case, the answer is the Identity Property of Multiplication. The Identity Property of Multiplication states that any number multiplied by 1 will result in the original number. In other words, 1 is the identity for multiplication because multiplying any number by 1 does not change the number's value. Hence, 6*1 still yields 6, validating this property.

Answer:

x=3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

2(2x−17)+4=−3(3+x)

4x+−34+4=−9+−3x  {distribute}

4x+−30=−3x−9   {combine like terms}

Step 2: Add 3x to both sides.

4x−30+3x=−3x−9+3x

7x−30=−9

Step 3: Add 30 to both sides.

7x−30+30=−9+30

7x=21

Step 4: Divide both sides by 7.

7x/7=21/7

x=3

4x - 3x = -9 + 30 2 (2x - 17) + 4 = -3 (3 + x)

So, we are going to DISTRIBUTE

Lets work on the left side of the equation first

Multiply 2 on the out side of the parenthesis by what is on the inside

2 x  2x = 4x

2 x  -17 = -34

So on the left side we now have

4x - 34 + 4

add 4

4x - 30

Let's do the same thing on the other side

-3  x  3 = -9

-3 x  X = 3x

Now let's put everything together

4x - 30 = -9 + 3x

COMBINE LIKE TERMS

x = 21
