He added a mystery substance, M, to his experiment. Dr. Burrows used the equation 13.93 plus M equals 18.0 to find how much he added. How much of the mystery substance, M, did he add for his experiment? A. 5.17 B. 5.07 C. 4.07 D. 4.17

1 answer

To find how much of the mystery substance, M, was added, we can isolate M in the equation:

13.93 + M = 18.0

Subtract 13.93 from both sides of the equation:

M = 18.0 - 13.93

M = 4.07

Therefore, he added 4.07 units of the mystery substance, M, for his experiment.

The answer is C. 4.07.
