A + 1 circle = 9 circles
A + B = 9 circles
B + C = A + 5 circles
- A = _____ circles
- B = _____ circles
- C = _____ circles
A + 1 circle = 9 circles --- (1)
A + B = 9 circles --- (2)
B + C = A + 5 circles --- (3)
(a)
From (1)
A + 1 circle = 9 circles
A = 9 circles - 1 circle
A = 8 circles
(b)
Substitute A = 8 circles into (2).
A + B = 9 circles
8 circles + B = 9 circles
B = 9 circles - 8 circles
B = 1 circles
(c)
Substitute A = 8 circles and B = 1 circles into (3).
B + C = A + 5 circles
1 circles + C = 8 circles + 5 circles
1 circles + C = 13 circles
C = 13 circles - 1 circles
C = 12 circles
Answer(s): (a) 8; (b) 1; (c) 12
