If you would like to solve the equation 3 * (3 * x - 1) + 2 * (3 - x) = 0, you can calculate this using the following steps:
3 * (3 * x - 1) + 2 * (3 - x) = 0
3 * 3 * x - 3 * 1 + 2 * 3 - 2 * x = 0
9 * x - 3 + 6 - 2 * x = 0
7 * x + 3 = 0
7 * x = - 3 /7
x = - 3/7
The correct result would be - 3/7.
Answer:
6.5%
Step-by-step explanation:
All i did was subtract 65 from the 75 which gave me 10 and I divided that by the original cost which was 65. That gave me 6.5%. Another possible answer is 0.1538461538461538. I just tried my best.

625
Step-by-step explanation:
Convert 15300 to a percent,
We can convert it to it's lowest fraction,
120, and to find the percent just multiply it by 5 on top and bottom,
120 ×5×5
which equals, 5100
Then take the percent as a decimal, 0.5 and multiply it by 12500,
12500×0.5 which would give you: 625
