Answer:
54kg
Step-by-step explanation:
Body weight = B
Tail weight = T
Head weight = H
Total weight = F
Use equation = B + T + H = F
We are told that T = 9kg, H = T + (1/3) x B, B = H + T
We have 3 equations and 3 unknowns, solve the system of equations to find W.
B = H + 9
H = 9 + 1/3 x (H+9)=9+H/3+3 --> 2/3 x H = 12 --> H = 18
B = 18 + 9 = 27
F = 18 + 27 + 9 = 54kg
If Tommy can paint a fence in 7 hours, he paints 1/7 of a fence in 1 hour.
If Huck and Tommy get one fence done in an hour, Huck must be able to complete 1-(1/7)=6/7 of a fence in one hr.
6/7x=1
x=7/6
Final answer: 1 hour, 10 minutes
