Question

which word phrase describes the algebraic expression ( x - 16.5 )?
○ 16.5 decreased by x
○ x less 16.5
○ x more than 16.5
○ 16.5 minus x

Explanation:

• "16.5 decreased by x" translates to $16.5 - x$, which does not match $x - 16.5$.
• "x less 16.5" means subtracting 16.5 from x, which matches $x - 16.5$.
• "x more than 16.5" translates to $16.5 + x$, which does not match.
• "16.5 minus x" translates to $16.5 - x$, which does not match.

Answer:

x less 16.5
