Allisa [31]
At noon, the temperature was 36 degrees. At midnight, the temperature was 30 degrees. By 6:00 am it drooped 5 degrees. Since it dropped 5 degrees, you subtract 5 from 30, which equals 25. It then increased by 11 degrees. Since the temperature increased, you add 11 to 25, which equals 36. At noon, the temperature was 36 degrees.

Solve the following compound inequality: (1 point)
valentinak56 [21]

\quad \huge \quad \quad \boxed{ \tt \:Answer }

\qquad \tt \rightarrow \: x < -2 \:\: or \:\; x >4

____________________________________

\large \tt Solution  \: :

\textsf{First Inequality :}

\qquad \tt \rightarrow \:  - 2(x + 8) + 6 > x - 4

\qquad \tt \rightarrow \:  - 2x - 16 + 6 > x - 4

\qquad \tt \rightarrow \:  - 2x - 10 > x - 4

\qquad \tt \rightarrow \:  - 10 + 4  > x + 2x

\qquad \tt \rightarrow \:  - 6 > 3x

\qquad \tt \rightarrow \:  -   \cfrac{ 6}{3}  > x

\qquad \tt \rightarrow \:  - 2 > x

\qquad \tt \rightarrow \: \therefore x <  - 2

\textsf{Second Inequality :}

\qquad \tt \rightarrow \:  - 3x + 12 < 6(x - 4)

\qquad \tt \rightarrow \:  - 3x + 12 < 6x - 24

\qquad \tt \rightarrow \:  12 + 24 < 6x + 3x

\qquad \tt \rightarrow \: 36 < 9x

\qquad \tt \rightarrow \:  \cfrac{36}{9}  < x

\qquad \tt \rightarrow \: 4 < x

\qquad \tt \rightarrow \:  \therefore x > 4
