Dr. Burrows is measuring the weight of a substance for a science experiment. He added a mystery substance (m) to his experiment. Dr. Burrows used the equation 13.93 + m = 18.0 to find out how much he added. How much of the mystery substance (m) did he add to his experiment

1 answer

To find the amount of the mystery substance \( m \), we can solve the equation:

\[ 13.93 + m = 18.0 \]

To isolate \( m \), subtract 13.93 from both sides of the equation:

\[ m = 18.0 - 13.93 \]

Now, calculate the right side:

\[ m = 4.07 \]

So, Dr. Burrows added 4.07 units of the mystery substance to his experiment.
