Your question is incomplete i guess
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
Answer: Im pretty sure is A 4.57
Step-by-step explanation:
5(2x - 4) = 45
5(2x) - 5(4) = 45
10x - 20 = 45
10x = 45 + 20
10x = 65
x = 65/10
x = 13/ 2
Thus, x is equal to 13/2
The answer is B because you would multiply 3 with 2 giving you a total of 6 and then you add the 2 and you get 8
