Answer:
year 6.6025 if there is no typo in your question and numbers are right.
Step-by-step explanation:
G = 63205 + 2500x
S = 50000 + 4500x
since 9% of 50000 = 0.09(50000) = 4500
find when G = S
63205 + 2500x = 50000 + 4500x
subtract both sides by 2500x to move x terms to the right
63205 = 50000 + 2000x
subtract both sides by 50000 to move the number to the left, so we can get like terms on each side
13205 = 2000x
divide both sides by 2000
x = 6.6025

Answer:
45 workers.
Step-by-step explanation
In 90 hours 15 workers will build one wall
So in 90 hours it w1ll take 1 worker to build 1/15 of a wall.
In 30 hours he would build 1/45 of a wall.
So to build the whole wall in 30 days it will take 45 workers.
#8 is kind of a handful. But if you just look at what 'y' is doing as 'x' increases ... no matter where you look, 'y' is always decreasing whenever 'x' increases, so that's certainly not a 'direct' relationship.
#9 is correct. Good work.
