Algebraic Expressions Practice and Problem Solving: D

Write an algebraic expression for each phrase by filling in the blanks. The first is done for you.

1. Fifty decreased by two tenths of m.

Write the expression for “Fifty decreased by”
50
Two tenths 0.2
0.2 “of m” is written as
0.2 m, or
0.2m
Put the steps together.
“Fifty decreased by” 50 “two tenths of m” 0.2m or 50 0.2m

2. Ten minus three tenths of n.
Write the expression for “Ten minus”

Three tenths 0.
Three tenths of n is written as
0. m, or
0.n.
Put the steps together:
“Ten minus than three tenths of n”

51

step-by-step explanation:

73-22=51 the   mass number minus the amount of protons gives you the amount of neutrons

overpriced

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.

step-by-step explanation:

well if you round, things become much more simple. round 5.95 to 6, 4.25 to 4, and 1.05 to 1. now, add 6+4+1 and that would equal 11. so the items together would equal to about $11.
