One month ashley rented 3 movies and 5 video games for $38. the next month she rented 12 movies and 2 video games for a total of $53. find the rental cost for each movie and each video game.

Let m and v represent the cost of a movie rental and a video rental.

Then 3m + 5v = $38 and 12m + 2v = $53. Solve this system of linear equations:

3m + 5v = $38

12m + 2v = $53

Let's eliminate m. Mult. the first eqn by -4, obtaining -12m - 20v = $152.

Now add this result to the 2nd equation:

-12m - 20v = -$152

12m + 2v = $53

-18v = -$99

Solving this for v, the cost of renting one video, is v = $99/18, or $5.50.

Now sub $5.50 for v in 3m + 5v = $38:

3m + $27.50 = $38. Then m, the cost of renting one movie, is $10.50.

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.
