Which of the following is an extraneous solution of V-3x-2-X+2?
O x=-6
O x = -1
O X = 1
O x = 6

Solution: She has £36 remaining.

To solve this is fairly simple.  First we multiple 72 by .4 to get 40%.  This gives us 28.8.  

We then subtract 28.8 by 72 to get the money she has remaining after she spends 40%.  The answer to this is 43.2

Then she spends 1/6 on makeup.  So we divide 43.2 by 6 and multiply again by 5, which gives us 36.

Answer:

The number could be [tex]-7.5[/tex] or [tex]8[/tex].

Step-by-step explanation:

I'm going to assume this means "The square of a number is 60 greater than half of the number." Let the number be [tex]x[/tex]. The square of [tex]x[/tex] will be [tex]x^{2}[/tex]. "is" denotes that we use the "[tex]=[/tex]" sign, so our equation so far is [tex]x^{2} =[/tex] . Half of [tex]x[/tex] is [tex]\frac{1}{2}x[/tex], and "greater than" implies addition, so [tex]60[/tex] greater than [tex]\frac{1}{2}x[/tex] is [tex]\frac{1}{2}x+60[/tex]. Therefore, the equation is [tex]x^{2} =\frac{1}{2}x+60[/tex].

Solving for [tex]x[/tex], we get:

[tex]x^{2} =\frac{1}{2}x+60[/tex]

[tex]2x^{2} =x+120[/tex] (Multiply both sides of the equation by [tex]2[/tex] to get rid of the fraction)

[tex]2x^{2} -x-120=0[/tex] (Subtract [tex]x+120[/tex] from both sides of the equation to make it easier to solve)

[tex]2x^{2} +15x-16x-120=0[/tex] (Split [tex]-x[/tex] into [tex]15x-16x[/tex] to make the LHS easier to factor)

[tex]x(2x+15)-8(2x+15)=0[/tex] (Take a common factor out of the first two terms and the last two terms)

[tex](2x+15)(x-8)=0[/tex] (Take another common factor out)

[tex]2x+15=0,x-8=0[/tex] (Zero Product Property)

[tex]x=-7.5,8[/tex] (Solve)

Answer:

C. [tex]\sqrt{3x^2+21x}[/tex]

Step-by-step explanation:

When one multiplies two radicles, one multiplies each term in the radical by the term in the other radical, then one simplifies the result and puts the radical sign over the result. If there are any perfect squares one will take the terms out. In this scenario, such is not the case.

[tex]\sqrt{3x}*\sqrt{x+7}\\\\\sqrt{3x(x+7)}\\\\\sqrt{3x^2+21x}[/tex]

Answer: 1608.48

Step-by-step explanation:

Given:

The expression is

[tex]2\times 2\times 2\times 2\times 2[/tex]

To find:

The index notation of the given expression.

Solution:

Index: The power of a number and a variable is called its index.

Index notation: The expression which has a base and a power.

In the given expression 2 is multiplied 5 times, so by using the property of exponent we get

[tex]2\times 2\times 2\times 2\times 2=2^{1+1+1+1+1}[/tex]       [tex][\because a^ma^n=a^{m+n}][/tex]

[tex]2\times 2\times 2\times 2\times 2=2^{5}[/tex]

Therefore, the index notation of the given expression is [tex]2^5[/tex].

Answer:

Your answer is 27

I hope I helped, would appreciate brainliest! ;)

Step-by-step explanation:

'Percent (%)' means 'out of one hundred':

27% = 27 'out of one hundred',

p% is read p 'percent',

27% = 27/100 = 27 ÷ 100

Calculate percentage:

'Percentage' is obtained by multiplying 100 by 27%

27% of 100 is equivalent to multiplying them:

27% × 100 = ?

27% × 100 =

(27 ÷ 100) × 100 =

(27 × 100) ÷ 100 =

2,700 ÷ 100 =

27

Proof.

How do we check the result?

If 27% × 100 = 27 =>

Divide 27 by 100...

... And see if we get as a result: 27%

Note:

100/100 = 100 ÷ 100 = 100% = 1

Multiply a number by the fraction 100/100,

... and its value doesn't change.

n/100 = n%, any number.

Calculate the percent value:

27 ÷ 100 =

0.27 =

0.27 × 100/100 =

(0.27 × 100)/100 =

27/100 =

27%

So we have proved that the calculations are correct.

Step-by-step explanation:

to find the answer for 3y + 4 we have to find the value of y.

we can find that by using the second equation.

-2y+6=2

-2y+6-2 =0 (subtract 2 from both the sided)

4= 2y (we will bring the -2y to the other side of the equation and then subtract the 6-2 to get the 4)

4/2=y  (divide by 2 on both the sides)

∴ y=2

now we will plug in the y of value that we see as -2 into the first equation.

∴ 3y+4 will become

=  3(2)+4

=6+4

=10

Answer:

(b) Least to greatest numbers are -1.0, [tex]-\frac{1}{4}[/tex] , 0, 0.5, 1.5

(c) -1.0 <  [tex]-\frac{1}{4}[/tex]  < 0 < 0.5 < 1.5

Step-by-step explanation:

P.S - The exact question is -

Given - Kendra collected data for her science project. She surveyed

             people asking them how many hours they sleep during a

             typical night.

             The chart below shows how each person’s response compares

              to 8 hours (which is the answer she  expected most people to say).

Name                Number of Hours                       Compared to Hours

                         (usually slept each night)

Frankie                        8.5                                                    0.5

Mr. Fields                      7                                                      −1.0

Karla                             9.5                                                     1.5

Louis                             8                                                         0

Tiffany                            [tex]7\frac{3}{4}[/tex]                                                       [tex]-\frac{1}{4}[/tex]

To find - (a) Plot and label each of the numbers in the right-most column

                   of the table above on the number line below.

               (b) List the numbers from least to greatest.

                (c) Using your answer from part (b) and inequality symbols,

                     write one statement that shows the relationship  among all

                     of the numbers.

Proof -

(a)

We can see that the numbers in the right-most column are  0.5, -1.0, 1.5, 0, [tex]-\frac{1}{4}[/tex]

We can write [tex]-\frac{1}{4}[/tex] = -0.25

Now,

We have to label them in the number line

The number line is as follows :

(b)

Least to greatest numbers are -1.0, [tex]-\frac{1}{4}[/tex] , 0, 0.5, 1.5

(c)

By using inequality symbol, we get

-1.0 <  [tex]-\frac{1}{4}[/tex]  < 0 < 0.5 < 1.5

OR

1.5 > 0.5 > 0 >  [tex]-\frac{1}{4}[/tex]  > -1.0

Answer: a parallelogram

The diagram is missing, so i have attached it.

Answer:

-1000 ft

Step-by-step explanation:

From the diagram attached, we see that they went 1000 ft below the sea level.

Now an altimeter is used to measure altitude depth of an object relative to a fixed level which in this case the fixed level is the top of sea. Since the depth in this case is below sea level, it will be negative.

Thus,the altimeter will read -1000 ft

Answer:

The dolphins are shown 1,000 feet below sea level. The altimeter reading would be -1,000 feet.

In respοnse tο the questiοn, we may say that As a result, the measure οf angle 2 is 128°.

An angle is a fοrm in Euclidean geοmetry that is made up οf twο rays that meet at a pοint in the centre knοwn as the angle's vertex. Twο rays may cοmbine tο fοrm an angle in the plane where they are situated. An angle is generated by twο planes clash. They are referred tο as dihedral angles. An angle in plane geοmetry is a pοtential cοnfiguratiοn οf twο radiatiοns οr lines that represent a terminatiοn. The wοrd "angle" cοmes frοm the Latin wοrd "angulus," which meaning "hοrn." The vertex is the place where the twο rays, alsο knοwn as the angle's sides, meet.

Vertical angles are generated by twο crοssing lines that fοrm pairs οf οppοsing angles. Vertical angles are cοngruent, which means they have the same dimensiοn.

Because 1 and 2 are vertical angles, they have the same length.

Knowing that m1 = 128°, we may deduce that m2 = 128°, as they are both vertical angles.

As a result, the measure of 2 is 128°.

multiply both sides by 3 to get rid of the fraction

75.36 = 12.56h

divide both sides by 12.56

h = 6

Answer:

h = 6

Step-by-step explanation:

25.12=12.56/3 h

Answer:

17/10000

Step-by-step explanation:

not completely sure

The fraction is 17/10000.

A fraction is shown as a numerical value that describes a portion of a larger whole. A fraction can be a portion or section of any quantity taken from a total, where the total can be any number, a particular value, or an object.

Given ratio 0.034 yards to 60 feet

and to convert it in simplest form

we know 1 yard = 3 feet

and 0.034 yard can be written as 34/1000

so 34 yards = 3 x 34 feet

34 yards = 102 feet

34/1000 yards = 102/1000 feet = 51/500 feet

and ratio = 0.034 yards/60 feet = (51/500)/60

= 51/30000

17/10000

Hence the ration in fraction is 17/10000.

Answer:

Slope = -3, Y-intercept = -2, y = -3x -2

Step-by-step explanation:

There are multiple points plotted on the graph, but right now, we only need to focus on two.

(-2, 4) (-1, 1)

Using the ordered pairs, do delta y/ delta x to get the slope

(1-4)/(-1-(-2)

(-3)/(-1+2)

(-3)/(1)

Slope = -3

y = -3x + b

As shown on the graph, the y-intercept is -2. It is when x = 0

So, for the equation, substitute the found values.

y = -3x -2
