To determine whether \( x = 9 \) is a solution to the inequality \( 5.6x \leq 50 \), we can substitute \( x \) with \( 9 \) in the inequality and check if the inequality holds true.
Substituting \( 9 \):
\[ 5.6(9) \leq 50 \]
Calculating \( 5.6 \times 9 \):
\[ 5.6 \times 9 = 50.4 \]
Now, we check the inequality:
\[ 50.4 \leq 50 \]
This statement is false.
Therefore, the answer is False.
