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

Answer 1

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

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 $c$ $=(b+3c)-\frac{x}{5}$.
