If m is the midpoint of AB, AM =7x-3 and MB =4x+12. find the value of x and the length of AB

A___M___B

AM = MB

7x -3 = 4x +12

7x - 4x = 12 + 3

3x = 15

x = 15/3

x = 5

AM= 7x -3 = 7(5) - 3 = 35 - 3 = 32

MB = 4x + 12 = 4(5) + 12 = 20 + 12 = 32

AB = AM + MB

AB = 32 + 32 = 64

So; X = 5, AB = 64

I hope I helped you^_^

javeir earned 56 dollors more than kyle so kyle and javier had 14w but javier made 56 dollors more so 14w plus 56 equals 70w so kyle has 14w

step-by-step explanation: hope i plz give me brainliest with the points so this is not constant cause it says last week so its clearly not every week

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.
