Pls help me out, I need to know what value of x makes this equation true equation: 6(2x – 11) + 15 = 3x + 12

I have already found the answer to this equation (x = 7) but I need to know what value of x makes the equation true.

(If it's 7, my brain just needs a break from stuff, I've been up since 4 in the morning)

x = 7

Step-by-step explanation:

12x - 66 + 15 = 3x +12

12x - 51 = 3x + 12

9x = 63

x = 7

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.
