Solve for b
b-19=27

show how you got the answer

For value of b is 46 .

Step-by-step explanation:

An equation is a mathematical statement that two things are equal. It consists of two expressions, one on each side of an 'equals' sign.

An equation says that two things are equal.  It will have an equals sign "=" like this:  7 + 2  =  10 − 1  That equation says: what is on the left (7 + 2) is equal to what is on the right (10 − 1)  . So an equation is like a statement "this equals that" .

Here we have , b-19=27 or . Let's solve it step by step:

⇒

Adding 19 both sides

⇒

⇒

⇒

The value of b is 46.

Step-by-step explanation:

Therefore, to remove the -19 on the left side of the expression, you need add +19 on both sided of the expression.

The expression now becomes b-19+19 = 27+19

⇒ b = 27+19

Then, perform certain operations on the left side of the expression to get an exact value for b.

⇒ b = 46

The value of b is 46 and these are steps which must be followed for solving the given expression.

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.

the answer is d
