Cora had 20 dollars to spend on 3 gifts she spent 11 1/4 dollars on the gift A and 3 4/5 dollars on gift B How much money did she have left for gift C

Amount left for gift C = dollars

Step-by-step explanation:

Given that:

Amount Cora have to spent on gifts = $20

Amount spent on gift A = dollars

Amount spent on gift B = dollars

Amount spent on gift C = x

Total amount = Gift A + Gift B + Gift C

20 =

20 =

Dividing both sides by 20

Hence,

Amount left for gift C = dollars

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.
