Four times a number x is at least -12
an inequality is ?
the solution is ?

-16

Step-by-step explanation:

im just taking a guess.

x+4>-12

  -4   -4

4's cancel out and -12+-4=-16

Again this is just a guess.

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
