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 point)

Answer 1

To find out how much of the mystery substance (m) Dr. Burrows added to his experiment, we need to subtract 13.93 from both sides of the equation.

13.93 + m - 13.93 = 18.0 - 13.93

m = 4.07

Therefore, Dr. Burrows added 4.07 of the mystery substance (m) to his experiment.
