<h3>
Answers: 17 quarters and 51 dimes</h3>
========================================================
Work Shown:
x = number of quarters
3x = number of dimes
0.25x = value of just the quarters, in dollars
0.10(3x) = 0.30x = value of just the dimes, in dollars
0.25x+0.30x = 0.55x = total value in dollars
0.55x = 9.35
x = (9.35)/(0.55)
x = 17
Alison has <u>17 quarters</u> and 3x = 3*17 = <u>51 dimes</u>
17 quarters = 17*0.25 = $4.25
51 dimes = 51*0.10 = $5.10
17 quarters + 51 dimes = $4.25 + $5.10 = $9.35
The answers are confirmed.

Answer:
R(2, 4)
Step-by-step explanation:
The general equation for a circle centered at (h,k) with radius, R, is
(x-h)^2 + (y-k)^2 = R^2
Putting the values in formula,
(x-6)^2 + (y-1)^2 = 5^2
Putting the coordinates (2, 4) of the answer B(2-6)^2 + (4-1)^2 = 25
(-4)^2 + 3^2 = 25
16 + 9 = 25
25 = 25
R.H.S = L.H.S
So according to the above solution,
B) R(2, 4), is the correct answer.
