What is the value of c in the equation 2(x-3)+9=3(x+1)+x

x = 0  (I must assume you had a typo since c is not a variable in this equation!

Step-by-step explanation:

Solve for x:

2 (x - 3) + 9 = 3 (x + 1) + x

2 (x - 3) = 2 x - 6:

2 x - 6 + 9 = 3 (x + 1) + x

Grouping like terms, 2 x - 6 + 9 = 2 x + (-6 + 9):

2 x + (-6 + 9) = 3 (x + 1) + x

9 - 6 = 3:

2 x + 3 = 3 (x + 1) + x

3 (x + 1) = 3 x + 3:

2 x + 3 = 3 x + 3 + x

Grouping like terms, 3 x + x + 3 = (3 x + x) + 3:

2 x + 3 = (3 x + x) + 3

3 x + x = 4 x:

2 x + 3 = 4 x + 3

Subtract 4 x from both sides:

(2 x - 4 x) + 3 = (4 x - 4 x) + 3

2 x - 4 x = -2 x:

-2 x + 3 = (4 x - 4 x) + 3

4 x - 4 x = 0:

3 - 2 x = 3

Subtract 3 from both sides:

(3 - 3) - 2 x = 3 - 3

3 - 3 = 0:

-2 x = 3 - 3

3 - 3 = 0:

-2 x = 0

Divide both sides of -2 x = 0 by -2:

(-2 x)/(-2) = 0/(-2)

(-2)/(-2) = 1:

x = 0/(-2)

0/(-2) = 0:

 x = 0

I am not sure if you mean x or c, but x would be equal to 0

Step-by-step Explanation:

Step 1: Simplify both sides of the equation.

2 (x - 3) + 9 = 3 (x + 1) + x

(2) (x) + (2) (- 3) + 9 = (3) (x) + (3) (1) + x

2x + - 6 + 9 = 3x + 3 + x

(2x) + (- 6 + 9) = (3x + x) + (3)

2x + 3 = 4x + 3

Step 2: Subtract 4x from both sides.

2x + 3 - 4x = 4x + 3 - 4x

- 2x + 3 = 3

Step 3: Subtract 3 from both sides.

- 2x + 3 - 3 = 3 - 3

- 2x = 0

Step 4: Divide both sides by - 2.

- 2x/- 2 = 0/- 2

x = 0

answer: sensy

step-by-step explanation:

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
