What is the area of a circle with a radius of 6 in.? Use 3.14 for the value of
pi,

Answer:

2.5

Step-by-step explanation:

-x=2-3x+3

Add 3x to both sides:

2x=5

Divide both sides by 2:

x=2.5

Hope this helps!

Answer:

x = 2.5

Step-by-step explanation:

-x = 2 - 3x +3

Combine like terms

-x = -3x+5

Add 3x to each side

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

2x = 5

Divide by 2

2x/2 = 5/2

x = 2.5

Answer:

40 seconds

Step-by-step explanation:

9 seconds = 18 feet

Answer:

n = -6

Step-by-step explanation:

n + 2 = -14 - n

2n + 2 = -14

2n = -12

n = -6

Answer:

Step-by-step explanation:

So in the case of "n" being any given variable, (basically saying it could be replaced by x, or any other variable) the answer would be,

n = -6

Work:

n + 2 = -14 - n

Cancel out the negative n on the right side by adding one n to both sides.

n + n = 2n

2n + 2 = -14

Get rid of the 2 on the left side, isolating the variable (2n)

2 + 14 = -12

2n = -12 is the final equation, and the last step is to divide both sides by 2, again isolating the variable.

Final answer is,

n = -6.

Answer:

coefficient for k: -2

constant term?: -5

degree of the polynomial: 2

Step-by-step explanation:

The coefficient for k is the number that multiplies k. In this case:

7kn+2k^2-2k-2n-5+5n^2

The constant term is the number that doesn't multiply any variable. In this case:

7kn+2k^2-2k-2n-5+5n^2

The degree of a polynomial is the highest of the degrees of the polynomial's monomials. In this case, the highest monomials are:

7kn+2k^2-2k-2n-5+5n^2

all of them second degree

The factor with the sum of 43 is 18+25

25-18=7 so the difference is 7

hope this helps

Step-by-step explanation:

The difference between the numbers be 25 -18 = 7.

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

let the two numbers be x and y

The sum of two numbers is 43

x+ y = 43.....(1)

and, product is 450

xy = 450

y= 450 / x

put value of y in equation (1)

x+ 450/x = 43

x² - 43x + 450 = 0

x² - 18x - 15x + 450 = 0

x( x- 18) - 15 ( x- 18)= 0

(x- 15) ( x- 18)= 0

x= 15, 18

So, the number are 18 and 25.

Hence, the difference between the numbers be 25 -18 = 7.

Answer:

a reflection across line m answer is b

Step-by-step explanation:

A reflection across lime m is the final transformation of pre-image GHJK to image G'H"J"K". Option B is correct.

The final transformation is to determine that transition states have been shown in the image that describes how pre-image GHJK transformed to image G'H"J"K".

Reflection is defined in an atmosphere as when the beam of light or wave strikes to the plane or curved surface deviates back from the atmosphere.

Steps of Transformation
Pre-image GHJK first rotates anticlockwise by an angle of 90° to G'H'J'K'.
Then G'H'J'K' reflected across the line m to G'H"J"K". It is the final transition state.

Thus, a reflection across lime m is the final transformation of pre-image GHJK to image G'H"J"K".

Step-by-step explanation:

The equation of a line in standard form is

Ax + By = C ( A is a positive integer and B, C are integers )

Given

- 2(x - y) - 10 = 0 ← distribute parenthesis on left side

- 2x + 2y - 10 = 0 ( add 10 to both sides )

- 2x + 2y = 10 ( multiply through by - 1 )

2x - 2y = - 10 ← in standard form
