Question

12, 8x -177 0 3 x 4,5212, 9 x - 16,6 < 7, 1 x + 19,8​

Answer 1

5 * ( 4 + 5 ) = 5 * 9 = 45 3 * ( 10 - 7 ) = 3 * 3 = 9

Answer 2

It seems like you've provided a series of equations and inequalities with variables x. Let's break them down one by one and solve for x if possible:

1. 12 = 8x - 177

   First, add 177 to both sides of the equation:

   12 + 177 = 8x

   189 = 8x

   Now, divide both sides by 8 to isolate x:

   x = 189 / 8 x = 23.625

2. 9x - 16.6 < 7

   Add 16.6 to both sides of the inequality:

   9x < 7 + 16.6 9x < 23.6

   Now, divide both sides by 9 to isolate x:

   x < 23.6 / 9 x < 2.622

So, the solutions for x are:

1. x = 23.625
2. x < 2.622

Please note that these are the solutions for the given equations and inequalities.
