Solve graphically
First, we need to determine the inequalities of the system.
For number of coins, we have:
because the number of coins is not less than 20
For the worth of coins, we have:
because the worth of coins is not more than 0.80
So, we have the following equations:


Make y the subject in both cases:


Divide through by 0.01



The resulting inequalities are:


The two inequalities are plotted on the graph as shown in the attachment.
--- Blue
--- Green
Point A on the attachment are possible solutions
At A:

Answer:
The given sequence is geometric sequence
In the given pattern we have next number is 
Step-by-step explanation:
Given numbers are 64,-16,4,-1
To identify the pattern of the given numbers :
Let
,
,
and 
To find the next number that is 
common ratio 





Therefore the common ration is 
Therefore the given sequence is geometric sequence
The nth term of the geometric sequence is 
Now find the 5th term so put n=5 ,
we have





Therefore 
Answer:
v = 18
Step-by-step explanation:
8/3v = 48
were going to have to get 3 on the other side, so were going to cancel it out and multipliy it because it is a fraction
now we would have 8v = 48*3
48*3=144
now the equation looks like this 8v = 144
to isolate v we can divide 8 on both sides
which brings us to v = 18
