Answer

The sentence is translated into the algebraic equation: $\frac{1}{4}x - 5 = 32$

Work Step by Step

We want to translate this problem into an algebraic expression or equation. We need to analyze the terminology. $\frac{1}{4}$ of a number: (1) "Of" means "to multiply." (2) We use the variable $x$ to represent the number. We then get for this portion: $\frac{1}{4}$ x $x$ or $\frac{1}{4}x$ Decreased by $5$ means to subtract by $5$, so we get: $\frac{1}{4}x - 5$ "Is" means "equals." So now we have the whole sentence translated as: $\frac{1}{4}x - 5 = 32$
