A nickel is equal to 5 cents or 0.05 dollars.
A quarter is equal to 25 cents or 0.25 dollars.
Let number of nickels be = n
Let number of quarters be = q
...........(1)
As it is given, there are 3 more nickels than quarters so equation becomes,
................(2)
Plug in the value of 'n' from (2) in (1)

= 


As
we get, 
Hence, there are 12 nickels and 9 quarters.
Answer:

Step-by-step explanation:
we have the points
(-3,1) and (0,3)
step 1
Find the slope m of the line
The formula to calculate the slope between two points is equal to

substitute the values


step 2
Find the equation of the line in slope intercept form

we have

----> the y-intercept is the point (0,3)
substitute the values

step 3
Find the equation of the inequality
we know that
The slope is positive
Everything to the left of the line is shaded ( The inequality is of the form y > ax+b or y ≥ ax+b)
Is a dashed line (The inequality is of the form y > ax+ b or y < ax+b)
therefore
The equation of the inequality is of the form y > ax+b
The inequality is

see the attached figure to better understand the problem
Answer:
y-2 = 3/10(x+3)
Step-by-step explanation:
3y = 10
y = 10/3
looking for perpendicular so slope = 3/10
using the given point
y-2 = 3/10(x+3)
The circumference is pi times the diameter of the circle. The radius is half of the diameter. In this case, the radius is then 36.
Answer:
<h2>7y² - 6y -17</h2>
Step-by-step explanation:
(-2y^2-11y-7)-(-9y^2-5y+10) (firstly, we remove the brackets)
-2y^2 - 11y - 7 + 9y^2 + 5y - 10
= (-2y^2 + 9y^2) + (-11y + 5y) + (-7 - 10)
= (7y²) + (-6y) + (-17)
