11 POINTS FOR YOU!!! Math wizzes please :)

Okay I am getting ready to send in my algebra test but wanted my answers checked first :) Here is my test.

Simplify

1. 10+(6)(2)=22
2. 6(15-10)=10
3. 6 to the 2nd power - 2(3)to the 2nd power=18
4. I-7I-I7I=-14

Translate the following into numbers and symbols

22. One-third the difference of ten and x is 5
(1/3) x (10-x)=5

23. Eight less than the product of 3 and a equals 5
3a - 8 = 5

Write the expression below as a verbal sentence

24. 7 < a/9
-
* the minus is supposed to be under the lesser/greater sign

Seven less than the difference of a over nine

For each expression below, write in the correct symbol <, or >.

25. 30/1 > 30/100
27. -3 > .5 < 2

Much appreciated. I will in return for the best answer will give you 11 points. (thumbs up plus selecting you for best answer)

1. Correct

2. 90 - 60 = 30 Incorrect

3. 6^2 - 2*3^2 = 36 - 18 = 18 Correct

4. |-7| - |7| = 7 - 7 = 0 Incorrect

22. 1/3 * (10-x) = 5
10-x = 15
x = -5 Incorrect

23. 3a - 8 = 5
3a = 13
a = 13/3 = 4.33

24. "Seven is less than or equal to a divided by nine" Incorrect

25. Correct

27. Correct

Even aside from the fact that I'm not seeing your answers for us to be able to tell you if you are correct or not, and perhaps guide you toward correct answers (rather than *giving* you a correct answer for each and every one of these questions)...
I believe that you mis-copied several of the initial questions - as they do not work out correctly in a decimal system.

1)Correct
2)Wrong the answer should be 30. 90-60=30 after you distribute.
3)Correct
4)Wrong this one should be 0 because the absolute value of -7 is 7, so 7-7=0
22)Correct
23)Correct
24)No this one should be 7 is less than or equal to a divided by 9
