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?

Answer 1

To find out how much of the mystery substance Dr. Burrows added, we can isolate the variable m in the equation 13.93 + m = 18.0.

Subtracting 13.93 from both sides of the equation, we get:
m = 18.0 - 13.93.

Simplifying the right side of the equation, we have:
m = 4.07.

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