Answer:
![x=9](https://tex.z-dn.net/?f=x%3D9)
Step-by-step explanation:
ABC is the sum of the angles CBD and ABD. So:
![\angle ABC=\angle CBD+\angle ABD](https://tex.z-dn.net/?f=%5Cangle%20ABC%3D%5Cangle%20CBD%2B%5Cangle%20ABD)
Substitute them for their equations:
![(-7x+241)=(-4x+123)+(154-7x)](https://tex.z-dn.net/?f=%28-7x%2B241%29%3D%28-4x%2B123%29%2B%28154-7x%29)
Solve for x. Combine like terms on the right:
![-7x+241=-11x+277](https://tex.z-dn.net/?f=-7x%2B241%3D-11x%2B277)
Add 11x to both sides:
![4x+241=277](https://tex.z-dn.net/?f=4x%2B241%3D277)
Subtract 241 from both sides:
![4x=36](https://tex.z-dn.net/?f=4x%3D36)
Divide both sides by 4:
![x=9](https://tex.z-dn.net/?f=x%3D9)
The value of x is 9.
And we're done!
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 answer to this question is y=3, x=2
I hope this helps!!!!!!!!
Answer: 16
Radical 256 (square root) = 16 x 16
If you but any number in for x and you get an untrue answer is no solution but if its true and thats the only answer then is a solution
