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?
A) 4.07 ounces
B) 4.97 ounces
C) 5.03 ounces
D) 5.17 ounces
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.
To find out how much of the mystery substance 'm' Tim added to his experiment, we need to solve the equation 12.93 + m = 17.0.
To isolate 'm' and solve for it, we can rearrange the equation by subtracting 12.93 from both sides:
m = 17.0 - 12.93
Simplifying the right side of the equation, we have:
m = 4.07
So, Tim added 4.07 ounces of the mystery substance (m) to his experiment.
Therefore, the correct answer is:
A) 4.07 ounces
To find out how much of the mystery substance (m) Tim added to his experiment, we can solve the equation 12.93 + m = 17.0.
Let's isolate the variable "m" by subtracting 12.93 from both sides of the equation:
m = 17.0 - 12.93
Simplifying the right side of the equation:
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
