N=nickels
d=dimes
n+d = 30
n+18 = 30
n = 30-18
n = 12 (number of nickels)
therefore Mary has 12 nickels
Answer:
(-30, 10)
multiply -20/60 by -0.5 each and you get 10/-30
this is the only pair achievable by proportion.

The 100t in the equation means the initial velocity of the rockey is 100
Step-by-step explanation:
According to the text and graph.
The s reprecets the yintexept of the graph
h(t)=5+100t-16t²
h(t)=100-32t
k(0)=100
in terms of the rocket The 100t in the equation means the initial velocity of the rockey is 100
