Answer:

x = -9

Step-by-step explanation:

To solve these types of questions,

a). If both the sides of the equation are different,

    2x + 3 = 3x - 6

   There will be exactly one solution.

b). If the coefficient of variable 'x' is same in both the sides of the equation,

    x - 3 = x - 6

    Solution set will be 'none'.

c). If both the sides of the equation are exactly same then equation will have infinite solutions.

   2x + 3 = x + x + 3

In the given equation,

6x - (5x + 5) = -8 - 2(x + 12)

Further simplify the equation,

(6x - 5x) - 5 = - 8 - 2x - 24

x - 5 = -2x - 32

x + 2x = 5 - 32

3x = -27

x = -9

Answer:

Step-by-step explanation:

Represent the equation as follows:

[tex]a * b = c[/tex]

Where a,b and c are decimal numbers

To solve further, we make use of trial by error method

Let

[tex]a = 2.52[/tex]

[tex]b = 0.6[/tex]

Such that

[tex]2.5 * 0.6 = c[/tex]

[tex]1.512 = c[/tex]

[tex]c = 1.512[/tex]

This set of digits do not follow the rule in the question

Let

[tex]a = 2.55[/tex]

[tex]b = 1.6[/tex]

[tex]2.55 * 1.6 = c[/tex]

[tex]4.08 = c[/tex]

[tex]c = 4.08[/tex]

The result has only 2 non zeros (4 and 8)

Hence

[tex]2.55 * 1.6 = 4.08[/tex] answers the question.

However, there are other set of numbers that can be used too

One of the equation which illustrates and meets the conditions given is :

First number, x = 1.25

First number, x = 1.25 Second number, y = 0.2

Result = first Number × second number

Result = 1.25 × 0.2

Result = 1.25 × 0.2 Result = 0.25

Evaluating the result : 0.25

Number of digits = 3

Non - zero digits = 2

There are several values of x and y which will satisfy the 3 conditions given.

Therefore, the product of the values 1.25 and 0.2 gives the required output.

Answer:

Difference = 3x² + 3x + 1

See Explanation

Step-by-step explanation:

Required: How changes in sides of a cube affects its volume.

Take for instance the side of the cube is x.

The initial volume would be:

Volume = x * x * x

Volume = x³

When then dimension is increased by 1 unit, the new volume would be

Volume = (x + 1) * (x + 1) * (x + 1)

Expand the brackets

New Volume = (x² + 2x + 1)(x + 1)

New Volume = x³ + 3x² + 3x + 1

[Calculate the difference between both volumes]

Difference = New Volume - Initial Volume

Difference = x³ + 3x² + 3x + 1 - x³

[Collect like terms]

Difference = x³ - x³ + 3x² + 3x + 1

Difference = 3x² + 3x + 1

So, there will be a difference of 3x² + 3x + 1 when the dimension is increased from x to x + 1

Take for instance: a dimension of 2 units is increased to 3 units

Initial Volume = 2³ = 8

New Volume = 3³ = 27

Difference = 27 - 8

Difference = 19

Using the derived formula (x = 2)

Difference = 3x² + 3x + 1

Substitute 2 for x

Difference = 3 * 2² + 3 * 2 + 1

Difference = 3 * 4 + 6 + 1

Difference = 12 + 6 + 1

Difference = 19

Answer:

Options (C), Option (D), Option (E), Option (F).

Step-by-step explanation:

It's given in the question,

ΔTUV ≅ ΔWXY

Therefore, corresponding sides and angles will be congruent.

∠T ≅ ∠W

∠U ≅ ∠X

∠V ≅ ∠Y

TV ≅ WY

UV ≅ XY

TU ≅ WX

By these properties, following options will be the correct options.

Option (C). ∠V ≅ ∠Y

Option (D). TV ≅ WY

Option (E). UV ≅ XY

Option (F). ∠X ≅ ∠U

Answer:

C,D,E, and F are correct

Step-by-step explanation:

In order to solve problems like this, you need to see which angles and segment correspond. Also, you would need to make sure that the order is the same on both sides of the equal side. For example, the first angle on one side of the equal sign will be congruent to the FIRST angle on the other side of the equal side.

Taking any number x, and adding on its opposite -x, leads to x+(-x) = x-x = 0

This is the inverse property of addition.

A numeric example would be 7 + (-7) = 7-7 = 0

Going back to x-x = 0, we can replace x with any expression (whether simple or complicated) we want.

So in this case, we replace each 'x' with 'x+3' to get (x+3)-(x+3) = 0

The equation (x+3)-(x+3) = 0 has infinitely many solutions. The solution set is the set of all real numbers. We can replace x with any number and the original equation will simplify to a true statement.

Answer: 7+0.7+0.05

Since 7 is in the ones place it goes in front of the decimal. .7 is in the tenth place because it's behind the decimal. .05 is also behind the decimal so it's in the hundredths place.

Answer:

[tex]x=6[/tex]

Step-by-step explanation:

So we have the equation:

[tex]3(x+1)=9+2x[/tex]

Distribute the left side:

[tex]3x+3=9+2x[/tex]

Subtract 2x from both sides. The right side cancels:

[tex](3x+3)-2x=(9+2x)-2x\\x+3=9[/tex]

Subtract 3 from both sides:

[tex](x+3)-3=(9)-3\\x=6[/tex]

So, x is 6.

4 × 8 = 32

if the value of width/length can be repeated, 6 total different values.

1 × 32 = 32

2 × 16 = 32

4 × 8 = 32

32 × 1 = 32

16 × 2= 32

8 × 4= 32

you can easily find all factors using online factor calculator

first lets collect the x's so -12x + x is -11x (think about a number line if you are not sure) then we minus 3x so we get  -14x

-9 + 5 is -4 then if we minus 1 we get -5 so

- 14x - 5

Answer: Combine each like term. Any number in this expression with the variable x is a like term. -12x+1x-3x=-14x. The numbers with no variable are like terms. -9+5-1=-5. The simplified expression is -14x-5.

Then, convert miles to feet. And hours to minute.

To do this simultaneously,

Convert miles to feet and hours to minutes.

There should be 3 "fractions" to multiply.

The first should be the original problem:

3miles/1 hour. (3 miles per hour).

The second should be 1 hour/60min. (1 hour per 60 min).

The third should be 5280 ft/1 mile. (5280 feet per mile).

The second and the third fractions are to convert miles to feet and the hours to minutes.

The statement which is true about the slope of the given graphed line is that the slope is positive.

Slope is the proportion of decrease or increase in variable y due to increase and decrease in variable x. The formula of calculating slope is as under:

Dance instructor can chose 4 students out of 10 if order doesn't matter in 210 ways

A combination is a selection of all or part of a set of objects, without regard to the order in which objects are selected.

For example, suppose we have a set of three letters: A, B, and C. We might ask how many ways we can select 2 letters from that set. Each possible selection would be an example of a combination.

Formula of combination:

[tex]C_{n} ^{r} = \frac{n!}{r! (n-r)!}[/tex]

Where

nCr is   the selection of objects from a group of objects where order of objects does not matter.

n is the total number of objects

r is the number of selected objects.

According to the question

A dance instructor chose four of his 10 students to be on stage for a performance and order does not matter .

i.e,

if we have to chose and order does not matter that means we have to use combination .

[tex]C_{n} ^{r} = \frac{n!}{r! (n-r)!}[/tex]

Total number of students (n)= 10

Number of selected students (r) = 4

[tex]C_{n} ^{r} = \frac{n!}{r! (n-r)!}[/tex]

[tex]C_{n} ^{r} = \frac{10!}{4! (6)!}[/tex]

[tex]C_{n} ^{r} = \frac{10*9*8*7}{4*3*2*1 }[/tex]

[tex]C_{n} ^{r} = \frac{5040}{24 }\\[/tex]

Answer:

2x

Step-by-step explanation:

Factor both terms given to simplest terms:

8x = 2 * 2 * 2 * x

22xy = 2 * 11 * x * y

Note that in each case, there is the factor of 2 & x that is shared by both. These are what is used to find the Greatest Common Factor. Multiply both terms together:

2 * x = 2x

2x is your GCF.

~

First find the greatest common factor of 8 and 22.

To find the greatest common factor of 8,

begin by dividing 8 by all the numbers you can.

8 ÷ 1 = 8

8 ÷ 2 = 4

Notice that I stopped here because if I continued

dividing, I would be dividing 8 by 4 which is 2.

Make sure to stop dividing when you see numbers repeat.

So the factors of 8 are 1, 2, 4, and 8.

Now do the same thing for 22.

22 ÷ 1 = 22

22 ÷ 11 = 2

So the factors of 22 are 1, 2, 11, and 22.

Now look for the largest number shared by the two lists.

In this case, the largest number is 2.

Now let's move to the variables.

To qualify for the Greatest Common Factor,

the variable must appear in every monomial.

Since the y doesn't appear in every monomial, it doesn't qualify.

However, notice that the x does appear in every monomial.

If the variable does appear in every monomial, the Greatest

Common Factor will use the smallest power on that variable.

Since the smallest power for x in both monomials is x, we use x.

So our greatest common factor is 2x.
