D = 2C
J = 1/3D
J = C - 1
J = 1/3D
J = 1/3(2C)
J = 2/3C
2/3C = C - 1
2/3C - 3/3C = -1
-1/3C = -1
C = -1 * -3
C = 3...there are 3 cats
J = C - 1
J = 3 - 1
J = 2.....there are 2 collars
Answer:
6 inch, 12 inch, 30 inch
Step-by-step explanation:
x + 2x + 5x = 48

6 x 5 = 30
12, 24, 36, 48, 60,
15, 30, 45, 60
