Answer:
D) b + 6 = 17; b = 11
Step-by-step explanation:
Marco checked out a total of 17 items. It is given that 6 of them are movies. Set the equation. Let b = the amount of books checked out:
Whole = Part A + Part B
Whole = 17
Part A = movies = 6
Part B = books = b
17 = 6 + b
Isolate the variable, b. Note the equal sign, what you do to one side, you do to the other. Subtract 6 from both sides:
17 (-6) = 6 (-6) + b
b = 17 - 6
b = 11
D) b + 6 = 17; b = 11 is your answer.
