Answer:
<em>Number of nickels = 6</em>
<em>Number of dimes = 14</em>
<em>Number of quarters = 23</em>
<em></em>
Step-by-step explanation:
Total number of coins = 43
Let number of nickels = n
Let number of dimes = d
Let number of quarters = q

Money in n nickels = 
Money in d dimes = 
Money in q quarters = 
Total money = $7.45

The sum of the numbers of nickels and dimes is 3 less than the number of quarters.
i.e.

Let us put the value in (1):

Putting the value of q in (1) and (2):
n+d = 20 .... (3)

(4) - (3):
d = 14
Now, from (3):
n = 6
<em>Number of nickels = 6</em>
<em>Number of dimes = 14</em>
<em>Number of quarters = 23</em>
(3,2)
(-2,4)
that makes both equations
16=16
2=2

Simple, finding markdown, use these two formulas.
Markdown=Original-New
and
Percent Markdown= Markdown Amount/Original*100
So,
Markdown=612-450
M=162
Markdown%= 162/612*100
M%=0.2647*100
M%=26.5 (rounded)
Thus, there was a 26.5% decrease.
Answer:
y=2x+3 C
Step-by-step explanation:
The first point (0,3) tells us the y intercept of 3 and we can use the slope formula to figure out that the slope is 2.
