Question

Ava spent three hours yesterday practicing the piano. She is going to spend more than 3 hours practicing today. Which number line models the total amount of time Ava will practice piano in all? @phi

Answer 1

you're right

Answer 2

Thanks

Answer 3

because 3 + [more than three] cannot be 6.

Answer 4

or rather, 3 + [more than three] + [positive number] cannot

Answer 5

x > 6 is the equation

so an open dot, and an arrow pointing to bigger numbers.

Answer 6

common sense should rule out the arrows pointing toward negative numbers (nobody practices for negative hours). So its A or B without knowing any details.

the "more than" translates to > sign (and an "open circle")
so you don't even have to figure out it is x> 6 (because both A and B start at 6)
you just need to know more than goes with open circle.
