I need to know if I did this problem correctly:
5. Solve for x in x  3 >8
Work: x  3 >8
x > 8 +3
Anwer= x > 11
I also need help with these 2:
15. Comepare the quantity in Column A with the quantity in Column B.
Column A slope of y = 2x +2
Column B slope of 2y = 3x + 9
a. The quantity in Column A is greater.
b. The quantity in Column B is greater.
c. the two quantities are equal
d. the relationship cannot be determined on the basis of the information supplied.
22. Simplify .5(2.3 + 25)/ 1.5 to the nearest tenth.
Thanks

I don't know about 15.
5 looks right.
22. .5(27.3)/1.5
Divide both numerator and denominator by .5
25.3/3 = ?
