Answer:
Independent variable: b - books
Dependent variable: w - weeks
graph attached
Step-by-step explanation:
b = 2w + 3
b = total number of books collected
w = is the number of weeks
So, the number of books depend on the number of weeks, so
Independent variable: b - books
Dependent variable: w - weeks
The 3 angles of a triangle, when added, = 180 degrees
so if 2 of them are 70.....70 + 70 = 140
then the 3rd will be 180 - 140 = 40 degrees <==
