The answer is A
25 * 3 = 75, 5 * 8 = 40, 40 + 75 = 115
I hope this helps :)
You started with nothing: 0
He gave you 8: +8
You spend 6: -6
He gave you 5 more: +5
0 + 8 - 6 + 5 = 7 dollars left to spend.
Answer:
11 months
788 disc
Step-by-step explanation:
Let
x = number of months
Fry's Electronics;
= 920 - 12x
Blu-ray discs:
= 502 + 26x
Equate both equations
920 - 12x = 502 + 26x
920 - 502 = 26x + 12x
418 = 38x
x = 418/38
x = 11 months
number of months = 11
Substitute 11 into any of the equation
Fry's Electronics;
= 920 - 12x
= 920 - 12(11)
= 920 - 132
= 788 disc sold in that months

3. ![\displaystyle 1 = x](https://tex.z-dn.net/?f=%5Cdisplaystyle%201%20%3D%20x)
2. ![\displaystyle -1 = x](https://tex.z-dn.net/?f=%5Cdisplaystyle%20-1%20%3D%20x)
1. ![\displaystyle 1 = x](https://tex.z-dn.net/?f=%5Cdisplaystyle%201%20%3D%20x)
Step-by-step explanation:
4. 7x - 2 = 9x + 10
- 9x + 2 - 9x + 2
_____________
![\displaystyle \frac{12}{-2} = \frac{-2x}{-2} \\ \\ -6 = x](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Cfrac%7B12%7D%7B-2%7D%20%3D%20%5Cfrac%7B-2x%7D%7B-2%7D%20%5C%5C%20%5C%5C%20-6%20%3D%20x)
3. 4x + 8 = 3(x - 1) + 12
4x + 8 = 3x - 3 + 12
4x + 8 = 3x + 9
- 4x - 9 - 4x - 9
____________
![\displaystyle \frac{-1}{-1} = \frac{-x}{-1} \\ \\ 1 = x](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Cfrac%7B-1%7D%7B-1%7D%20%3D%20%5Cfrac%7B-x%7D%7B-1%7D%20%5C%5C%20%5C%5C%201%20%3D%20x)
2. 3x + 7 - 2x = 4x + 10
x + 7 = 4x + 10
- 4x - 7 - 4x - 7
____________
![\displaystyle \frac{3}{-3} = \frac{-3x}{-3} \\ \\ -1 = x](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Cfrac%7B3%7D%7B-3%7D%20%3D%20%5Cfrac%7B-3x%7D%7B-3%7D%20%5C%5C%20%5C%5C%20-1%20%3D%20x)
1. −2x + 8 = 2x + 4
- 2x - 8 - 2x - 8
____________
![\displaystyle \frac{-4}{-4} = \frac{-4x}{-4} \\ \\ 1 = x](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Cfrac%7B-4%7D%7B-4%7D%20%3D%20%5Cfrac%7B-4x%7D%7B-4%7D%20%5C%5C%20%5C%5C%201%20%3D%20x)
