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?

Question

5.17
5.07
4.07
4.17
be sure you are positive with the answer

Answer 1

To find the amount of the mystery substance (m) that Dr. Burrows added, we can rearrange the equation 13.93 + m = 18.0 to solve for m.

Subtract 13.93 from both sides of the equation:
m = 18.0 - 13.93

m = 4.07

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

The correct answer is 4.07.
