A + 4 circle = 7 circles
A + B = 4 circles
B + C = A + 8 circles
- A = _____ circles
- B = _____ circles
- C = _____ circles
A + 4 circle = 7 circles --- (1)
A + B = 4 circles --- (2)
B + C = A + 8 circles --- (3)
(a)
From (1)
A + 4 circle = 7 circles
A = 7 circles - 4 circle
A = 3 circles
(b)
Substitute A = 3 circles into (2).
A + B = 4 circles
3 circles + B = 4 circles
B = 4 circles - 3 circles
B = 1 circles
(c)
Substitute A = 3 circles and B = 1 circles into (3).
B + C = A + 8 circles
1 circles + C = 3 circles + 8 circles
1 circles + C = 11 circles
C = 11 circles - 1 circles
C = 10 circles
Answer(s): (a) 3; (b) 1; (c) 10
