This question was answered in a heartbeat by others but I'll still post the solution anyway. Will try to get more difficult questions in the future that are less likely to be answered.

2.) -18 + (-12)

3.) x + 29 for x = -15

4.) -3/4 - (-1/4)

1) \(\displaystyle \frac{1}{4}-12 = \frac{1}{4} - \frac{48}{4}= \frac{-47}{4}\)

2) \(\displaystyle -18+(-12)=-18-12=-30\)

3) \(\displaystyle x + 29\) given $x=-15$. \(\displaystyle -15+29=29-15=14\)

4) \(\displaystyle \frac{-3}{4}- \frac{-1}{4}= \frac{-3}{4}+\frac{1}{4}=\frac{-2}{4}= - \frac{1}{2}\)
