Answer:
9 lb 3 oz
Step-by-step explanation:
(3 + 5) lb + (9 + 10) oz
8 lb + 19 oz
16 oz = 1 lb
(8 + 1) lb + (19 - 16) ox
9 lb 3 oz
Answer: 20.2
Add all the angles and set it equal to 180
Combine like terms
20x-2=180
X= 9.1
The equation for v is 2x+2
Replace x with 9.1 and then solve
Divide both sides by -3, and replace with . Then
Factorize the quadratic in to get
which in turn means
But for all real , so we can ignore the first solution. This leaves us with
If we allow for any complex solution, then we can continue with the solution we ignored:
