Hannah and francine have $120. hannah and peter have $230. peter has six times as much as francine. how much does hannah have?

The amount that Hannah has is $98

Step-by-step explanation:

Let

x-----> amount that Hannah has

y ----> amount that Francine has

z ----> amount that Peter has

we know that

----> equation A

----> equation B

-----> equation C

substitute equation C in equation B

----> equation D

we have

----> equation A

----> equation D

Solve the system of equations A and D by graphing

Remember that the solution is the intersection point both graphs

using a graphing tool

The solution is the point (98,22)

see the attached figure

Find the value of z

---->

therefore

The amount that Hannah has is $98

The amount that Francine has is $22

The amount that Peter has is $132

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.
