Find the value of n in each equation. write what n represents in the related division problem 643=4×160+n

n = 3; n represents a remainder in a division problem.

Explanation:

1) Finding n:

i) Given: 643 = 4 × 160 + n

ii) Do the operations: 643 = 640 + n

iii) Subraction property of the equality: 643 - 640 = n

iv)  Do the operations: 3 = n

n 3

2) Meaning of n

When you divide 643 by 4 the quotient is 160 and the remainder is 3, because 160 × 4 = 640, and 643 - 640 = 3.

This is, 3 is what is left when you split 643 into 4 getting 160 whole parts (plus the remainder, 3).

(3x-8) or (3x+8)

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.
