To solve the inequality \( h + 8 \leq 9 + 12 \):
-
First, simplify the right side: \[ 9 + 12 = 21 \] Therefore, the inequality becomes: \[ h + 8 \leq 21 \]
-
Next, subtract 8 from both sides: \[ h \leq 21 - 8 \] \[ h \leq 13 \]
The solution to the inequality is: \[ h \leq 13 \]
So the appropriate response is: h ≤ 13.
