Is the inequality always, sometimes or never true?
statuscvo [17]
In order to understand if the inequalities are always, never or sometimes true, you need to perform the calculations:

A) <span>9(x+2) > 9(x-3)
9x + 18 > 9x - 27
the two 9x cancel out and you get:
+18 > -27
which is always true.

B) <span>6x-13 < 6(x-2)
6x - 13 < 6x - 12</span> 
</span><span>the two 6x cancel out and you get:
- 13 < -12
which is always true

C) </span><span>-6(2x-10) + 12x ≤ 180
-12x +60 +12x </span>≤ 180
-12x and +<span>12x cancel out and you get:
60 </span><span>≤ 180
which is always true.

All three cases are always true.</span>
