Check the picture below.
since chords NQ and MP cross the center of the circle at R, that means that those two chords are diametrical chords and the angles made by both are vertical angles and thus twin angles, namely both are 18° as you see in the picture, so the angle NMP in magenta is really 162° + 18° + 18° = 198°, and we know the radius NR is 8.

Answer:
36 quarters   48 dimes  64 nickels
Step-by-step explanation:
quarter = q
dime = q+12
nickel = 2q-8
$17 = 1,700 cents
(q)25 + (q+12)10 + (2q-8)5 = 1,700
25q +10q+120  +10q-40 =1,700
45q+80 = 1,700
45q = 1620
q= 36      
  36     QUARTERS x25 =  900cents
  48 DIMES    x10      =         480 cents
   64 NICKELS x 5 =             320 cents
   TOTAL                              1,700 cents ($17)

The slope-intercept form of the equation for a line is ...
  y = (Slope)x + (y-intercept)
Put the given information in the appropriate spot in the equation. Simplify as required.
  y = (-1/3)x + 0
can be simplified to
y = (-1/3)x
