I don't know how to use it using a number line sorry
-1/3 - (-1/2)
Two minuses give us a plus
so:
-1/3 + 1/2
make the denominators the same and what you multiply at the bottom you multiply at the top (check online about adding fractions if you don't understand)
so:
-2/6 + 3/6 = 1/6
The value of 6 is 60, since it is in the tens place. Hope this helps!

Answer:
Step-by-step explanation:
Area of sector = angle/360 * pi * r^2
7.1 = 40/360 * 22/7 * r^2
7.1 = 1/9 * 22/7 * r^2
63.9 = 22r^2/7
r^2 = (7 * 63.9)/22
r^2 = 20.331818181818
r = square root of 20.331818181818
r = 4.51
d = r * 2 = 4.51 * 2 = 9.02
