If 67 is added to a number, the result is 41 less than three times the number

87.5

Step-by-step explanation:

The picture below explains better

54

Step-by-step explanation:

Let the number be A

A + 67 = 3A - 41

Combine like terms

41 + 67 = 3A - A

108 = 2A

Divide both sides by 2

108/2 = 2A/2

54 = A

Check

A + 67 = 3A - 41

54 + 67 = 3(54) - 41

121 = 162 - 41

121 = 121

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3

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.
