Wow, you spent a lot of time typing in all 24 of those problems and answers.
I'm a little concerned that you're taking a survey of your algebra knowledge and you don't understand any of it.
I'll help you with 3 problems.
You may want to consider that algebra.com may not be the best way to help yourself in this case.
1. Percentage and decimal
2.8% is the same as 2.8/100.
2.8/100=0.028
2. Percent means out of 100. Set up a proportion.
Solve for x.
168 is 35% of 480.
3. 2x(3x - 4y) 3x(-3x + 4y)
Use the distributive property.
Good luck.
