Build a variable expression for the given phrase.
-A number decreased by two 
A) $x - 2$
B) $2 - x$
C) $\frac { x } { 2 }$
D) $x + 2$

Quizplus · Accepted Answer

"Decreased by" implies subtraction, and the "two" is being subtracted from the number, so the expression should be written as the number (represented by the variable x) minus two, which is represented by (x - 2).
