Step-by-step explanation:

Let the number be x, then

[tex] \frac{x}{2 + 7} \\ \frac{x}{9} [/tex]

Answer:

6/5

Step-by-step explanation:

We can use the slope formula to find the slope

Slope formula: [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex], where the x and y values are derived from know points

The points chosen can vary as there are many given but the ones I chose were (6,9) and (11,15)

Now that we chose two points we want to define the variable ( the variables are x2, x1, y2 and y1 )

Define Variables

x1 = x value of first point which would be 6

x2 = x value of second point which would be 11

y1 = y value of first point which would be 9

y2 = y value of second point which would be 15

Now that we have defined our variables the next step is to plug in the variables into the slope formula

slope formula: [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]

y2 = 15, y1 = 9, x2 = 11 and x1 = 6

* plug in values *

[tex]m=\frac{15-9}{11-6}[/tex]

subtract top numbers

[tex]m=\frac{6}{11-6}[/tex]

subtract bottom numbers

[tex]m = \frac{6}{5}[/tex]

there is no simplification needed meaning that the slope in simplest form is 6/5

2√15 is your answer . Hope this helps you.

Answer:

2[tex]\sqrt{} 15[/tex] (decimal 7.74596)

Step-by-step explanation:

That sign is called a radical sign used to find square roots so it is used to extract or find the index of the number in this case the answer to that question

So you have

√6 √5 √2 first you find the value of the first number my finding the square root

(by changing the number into a decimal and using long division is the method i use)

Since √6 is √3 and √2 then you put them together like so

√2 √3 √5 √2

then you apply radical rule

(which the formula is √a √a = a,   a>0)

in this case it is √2 √2 = 2

and that equals

2 √3 √5

Apply radical rule again

(now that we did the formula the first time the formula changes now it is √a √b = √ab,    a>0, b>0)

now it is

2√3 x 5

now you just multiply 3 and 5and get 15

then you get

2[tex]\sqrt{} 15[/tex] (decimal 7.74596)

2400 is 100% of in this case, 8/8

So then we know that 1/8 of 2400 is 300 because we just divide it by 8. Sarah eats 5/8 that much so we multiply 300 by 5 which gives us 1500

Answer:

2400 x 5/8 = 1500

Answer:

The perimeter is the length of the outline of a shape. To find the perimeter of a rectangle or square you have to add the lengths of all the four sides. x is in this case the length of the rectangle while y is the width of the rectangle.

Answer:

-2

Step-by-step explanation:

Step-by-step explanation:

Absolute value of a number gives the positive quantity of the number.

For instance,

[tex]|3|=3, |-3|=3[/tex]

From this example, therefore we know that

[tex]\text{If }|x|=a,\text{ then }x=a\text{ or } -a. [/tex]

--------------------------------------------

In this question,

[tex]-2|2.2x-3.3|=-6.6[/tex]

[tex]|2.2x-3.3|=3.3[/tex]

[tex]2.2x-3.3=3.3\text{ or } -3.3[/tex]

[tex]2.2x=3.3+3.3 \text{ or }-3.3+3.3[/tex]

[tex]2.2x=6.6\text{ or } 0[/tex]

[tex]x=3\text{ or } 0[/tex]

Answer:

X = 3

Step-by-step explanation:

2(2.2x - 3.3) = 6.6

4.4x - 6.6 = 6.6

4.4x = 6.6 + 6.6

4.4x = 13.2

4.4x = 13.2

4.4 4.4

X = 3

Answer:

x = 12

Step-by-step explanation:

2(x-4)=16

2 times x +2 times -4 = 16

2x -8 =16

2x -8 (+8) =16 (+8)

2x = 24

2x (divided by 2) = 24 (divided by 2)

x = 12

Answer:

If your shape is a regular polygon (such as a square in the example above) then it is only necessary to measure one side as, by definition, the other sides of a regular polygon are the same length. It is common to use tick marks to show that all sides are an equal length.

Hope it helps love form india server

Answer:

they usually have double line on top of the lines of the shapes. for example square they have all the same lenght so they have double line signs on top of them

Answer:

First, set x equal to .93

x=.939393939393...

Then, since the repeating is by two digits, let's multiply x by 100

This would make 100x=93.9393939393...

Now, we can subtract 100x−x

This would leave us with 99x=93 because the repeating digits cancel out.

This looks much easier now right?

Just divide the 99 and isolate the x to get x=9399

Get the simplified fraction, and the final answer is x=3133

Answer:

Step-by-step explanation:

Let Numerator be : x

Denominator be : x + 7

Now,

Numerator = x + 6

Denominator = ( x + 7) - 5

According to the question,

[tex] \displaystyle \: \sf \dashrightarrow \: \frac{x + 6}{(x + 7) \: - 5} = \: \frac{3}{2} [/tex]

[tex]\displaystyle \: \sf \dashrightarrow \: 2(x + 6) \: = 3 \{ \: (x + 7 ) - 5\} \: [/tex]

[tex]\displaystyle \: \sf \dashrightarrow \: 2x \: + 12 \: = \: 3(x + 2)[/tex]

[tex]\displaystyle \: \sf \dashrightarrow2x + 12 \: = 3x + 6[/tex]

[tex]\displaystyle \: \sf \dashrightarrow \: 2x - 3x \: = \: 6 - 12[/tex]

[tex] \: \: \: \displaystyle \: \sf \dashrightarrow \: - x \: = - 6 \\ \\ \: \: \: \: \: \: \displaystyle \: \bf \dashrightarrow \: x \: = 6[/tex]

Numerator = 6

Denominator = x + 7

= 6 + 7

= 13

Thus ,

An expression in math is a sentence with a minimum of two numbers/variables and at least one math operation in it.

An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division. The terms involved in an expression in math are:

Constant: A constant is a fixed numerical value.

Variable: A variable is a symbol that doesn't have a fixed value.

Term: A term can be a single constant, a single variable, or a combination of a variable and a constant combined with multiplication or division.

Coefficient: A coefficient is a number that is multiplied by a variable in an expression.

Given:

A^B(B +2)

As, both are in ratio of multiplication and B is also the power for A.

There is no possible of decreasing the quantity.

Hence, if A is constant then B increasing and B is constant then A is increasing .
