A + 3 circle = 10 circles
A + B = 8 circles
B + C = A + 10 circles
- A = _____ circles
- B = _____ circles
- C = _____ circles
A + 3 circle = 10 circles --- (1)
A + B = 8 circles --- (2)
B + C = A + 10 circles --- (3)
(a)
From (1)
A + 3 circle = 10 circles
A = 10 circles - 3 circle
A = 7 circles
(b)
Substitute A = 7 circles into (2).
A + B = 8 circles
7 circles + B = 8 circles
B = 8 circles - 7 circles
B = 1 circles
(c)
Substitute A = 7 circles and B = 1 circles into (3).
B + C = A + 10 circles
1 circles + C = 7 circles + 10 circles
1 circles + C = 17 circles
C = 17 circles - 1 circles
C = 16 circles
Answer(s): (a) 7; (b) 1; (c) 16
