Question

For which equation would you subtract 3, and then multiply by 9 to solve? (see reply bar for multiple choice)

Answer 1

\[A. 9k + 3 = 40 \]
\[B. \frac{ k }{ 9 } + 3 = 40\]
\[C. 9k - 3 = 40 \]
\[D. \frac{ k }{ 9 } - 3 = 40 \]

Answer 2

So we are trying to find a number which is k. Go from last operation to first operation.
If you multiply an expression by 9 and find our value (k) that expression should be k/9. If you substract 3 from another expression and find k/9 it should be k/9+3.

The answer is k/9+3 = something (B)

Answer 3

Thank youuuuu!
