Tim is measuring the weight (in ounces) of a substance for a science experiment. Tim added a mystery substance (m) to his experiment. Tim used the equation 12.93 + m = 17.0 to find out how much he added. How much of the mystery substance (m) did Tim add to his experiment?

Question

A) 4.07 ounces
B) 4.97 ounces
C) 5.03 ounces
D) 5.17 ounces

Answer 1

To find the weight of the mystery substance (m), we need to solve the equation 12.93 + m = 17.0 for m.

Subtracting 12.93 from both sides of the equation:
m = 17.0 - 12.93
m = 4.07

Tim added 4.07 ounces of the mystery substance (m) to his experiment.

So the correct answer is A) 4.07 ounces.
