Answer:
- movie: $1.25
- video game: $5.25
Step-by-step explanation:
Let m and v represent the rental costs of movies and video games, respectively. The two rentals can be described by the equations ...
5m +3v = 22
2m +6v = 34
We notice that the coefficient of v in the second equation is 2 times that in the first equation. This will make it easy to eliminate v as a variable.
Subtracting the second equation from 2 times the first gives ...
2(5m +3v) -(2m +6v) = 2(22) -(34)
8m = 10 . . . . . . . . . . . simplify
m = 10/8 = 1.25 . . . . . divide by the coefficient of m
Using this in the second equation, we can find v:
2(1.25) +6v = 34 . . . . .substitute for m
6v = 31.50 . . . . . . . . . subtract 2.50
v = 5.25 . . . . . . . . . . . divide by the coefficient of v
The rental cost for a movie is $1.25; for a video game it is $5.25.
Answer:
(40.6) Is the answer
Step-by-step explanation:
| -72 + 32.4| + 18 / 6 * 3
we do the absolute value first. |-72+32.4| = 39.6
then multiplication (following PEMDAS) 6 * 3 = 18
18 / 18 = 1
39.9 + 1 = 40
I think you divide 5/9 divided by 2/3.
5/9 divided by 2/3=4/3 simplified=2/3.
Just know I'm terrible at math so this could be like totally off the hook crazy and wrong.
N is a placeholder for a number. In this case, it is 4
We will replace every copy of 'n' with '4' and then simplify
So n+8 turns into 4+8 which simplifies to 12
Is 12 less than or equal to 13? Yes it is. Specifically it is less than 13. So n = 4 is part of the solution set.
Here is how you'd write it all out using algebra
![n+8 \le 13](https://tex.z-dn.net/?f=n%2B8%20%5Cle%2013)
![4+8 \le 13](https://tex.z-dn.net/?f=4%2B8%20%5Cle%2013)
![12 \le 13](https://tex.z-dn.net/?f=12%20%5Cle%2013)
The last inequality is true so the first inequality is true when n = 4. This is another way to see that n = 4 is a solution.
