17. Summer Job. You offer to mow your neighbor's lawns for $20 or to wash their cars for $10. Your goal is to earn at least $1500 this summer. Write and graph an inequality
that represents the possible number of lawns, x, you would have to mow and cars, y, you
would have to wash in order to reach your goal. What ordered pair represents mowing 50
lawns and washing 65 cars? Is this order pair a solution of the inequality

do you have the measurements?

if you are saying purchasing 3 social media ads and one newspaper ad counts as one purchase then there are:

if you are asking how many of each then:

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.
