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
The more jobs there are, the more people are paid. If prices don't go up on imports, exports, and everyday items, salaries will go down. Which could eventually cause unemployment.
A+a+4+2a-3= 21
combine like terms
1+4a= 21
-1. -1
4a= 20
