the third option would be the best
Step-by-step explanation:
2/7 + 3/8 = 37/56 = .660
1/10 + 3/8 = 19/40 = .475
correct answer------------ 1/6 + 1/8 = 7/24 = .291
2/9 + 1/8 = 25/72 = .347
Okay so u turn 12/30 into a percentage which is 40% so ur answer is c
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
