Can I please get someones help:
Solve: 0.9x+9<_1.7x8

Glen~
Are you trying to figure out which side of the equation is greater than?
If so this is how it comes out if I remember correctly from my previous MAT class.
0.9x + 9 < 1.7x8
9.9x>6.3 
0.9X + 9 <= 1.7X  8.
Add 1.7X AND 9 to both sides:
0.9X  1.7X <= 8 9,
Combine liketerms:
0.8X <= 17,
Divide both sides by 0.8 and reverse inequality sign:
X => 21.25.
