7B
7A-55% boy, 45% girl
7B-30% boy, 70% girl
Answer:
Step-by-step explanation:
Looking at the diagram,
Line DT is parallel to line line BM, therefore, triangle DHT is similar to triangle BHM. This means that
DH/DB = TH/MH
DH = 15 + 6 = 21
TH = 9 + x
Therefore
(9 + x)/21 = 9/6
Cross multiplying, it becomes
6(9 + x) = 21 × 9 = 189
54 + 6x = 189
Subtracting 54 from the left hand side and the right hand side of the equation, it becomes
6x + 54 - 54 = 189 - 54
6x = 135
Dividing the left hand side and the right hand side of the equation by 6, it becomes
6x/6 = 135/6
x = 22.5

12x-21y=-42 -----> /3 (divided by 3 )
4x-7y=14 ------ (2)
4x-7y=-2 ------- (1)
how 4x-7y =14 an = -2
and if we
(2)-(1)
0=12
