Calculate

1). ( - 11.5) ( 16) =



2). ( . 5)3 =



3). ( - 9) 3 =



4). 7 - 12 =



Simplify by combining similar terms then find X in each of these equations:

5). X + X + X = 18



6). 3X - 2X = 15



7). 5X + 2X + 2X = 81



8). X + 5 - 3 = 10



9). 2X2 - X2 = 81



10). X + X + X + X + X = 30



Simplify by combining similar terms:

11). 5a + 2b + 5a + 4b =



12). 6a + 3b + 4c + 2a + 3b + 5c =



13). x + 5y - 2x + 16y =



14). 4a - 3b + 2a - 6b=



15). - 3x3 - x + 2x3+ 2x=



16). 5y3 - t3 - t + t3 =



17). 12c - 5d + 6c2 - 5d2 + 8d - 4c = v18). 6b - 2a + 3b - 4a2 - a + a2 =
