She has dimes and quarters 94 coins total the value is $19.30. how many of each does she have?

So setting up an equation might make this problem easier so I did.

The first equation is 0.25x+0.10y=19.30

The second equation is x+y=94

I forgot what to do after that so I started playing around with numbers using the two equations, and I ended up getting 28 dimes and 66 quarters.

0.25 (66) + 0.10 (28) = 19.30

66+28=94

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.

your answer is d 2,500
