<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.

With absolute value equations, you can make two equations.
The width of rectangle is 8 units.
Step-by-step explanation:
Given,
Area of rectangle = 40 units
Width = w
Length = w-3
Area = Length * Width
Factorizing the equation
Either,
w-8=0 => w=8
Or,
w+5=0 =>w= -5
As width cannot be negative, therefore
Width of rectangle = 8 units
The width of rectangle is 8 units.

Answer:
Step-by-step explanation:
Given that angle A is in IV quadrant
So A/2 would be in II quadrant.
sin A = -1/3
cos A =
(cos A is positive since in IV quadrant)
Using this we can find cos A/2
