A book store sells two notebooks plus a $30 backpack for the same amount as the price as the price for 12 notebooks. how much does one notebook cost?

$3 per notebook.

Step-by-step explanation:

i would start by taking the two notebooks away from the imaginary cart.

then a $30 backpack=10 notebooks.

if so, then, each notebook=$3 because 3x10=30.

if you re-add the two other notebooks then it would be twelve $3 notebooks=$36 ($30 backpack and two $3 notebooks) and 12x3=36 and 36=36

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.
