Question

What is the algebraic expression for the statement 'One-fifth of a number $x$ is subtracted from the sum of $b$ and thrice of $c$'?

• A. $\frac{x}{5}-3(b-3c)$
• B. $(b+3c)-\frac{x}{5}$
• C. $3(b+c)-\frac{x}{5}$
• D. $\frac{x}{5}-(b+3c)$

Answer 1

The correct option is B $(b+3c)-\frac{x}{5}$

One-fifth of a number $x$ $=\frac{x}{5}$.
Sum of $b$ and thrice of $c$ $=b+3c$.

One-fifth of a number $x$ is subtracted from the sum of $b$ and thrice of $c$ $=(b+3c)-\frac{x}{5}$.
