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?
Responses
A 4.07 ounces
B 4.97 ounces
C 5.03 ounces
D5.17 ounces
To find out how much of the mystery substance (m) Tim added to his experiment, we need to find the value of m in the equation 12.93 + m = 17.0.
Subtracting 12.93 from both sides of the equation, we have:
m = 17.0 - 12.93
m = 4.07
Therefore, Tim added 4.07 ounces of the mystery substance (m) to his experiment.
The correct answer is A) 4.07 ounces.
