Question

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

Answer 1

A) 4.07 ounces

Explanation:

12.93 + m = 17.0

Subtract 12.93 from both sides of the equation.

12.93 - 12.93 + m = 17.0 - 12.93

m = 4.07

Answer: A) 4.07 ounces
