Unit rate 1.29 for 12 rolls

.10705 cents (? your question doesn't specify if 1.29 is a dollar amount but I am assuming it is) per roll

Step-by-step explanation:

1.29/12=.10705

if 1.29 is cost in dollars round the number to $0.18

six digits cordnate grids are gayyy

step-by-step explanation:

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.
