The predicted time remaining has decreased by 30 years, so the second one would be the answer
6x−12+2x=3+8x−15
Simplify:
6x+−12+2x=3+8x+−15
(6x+2x)+(−12)=(8x)+(3+−15)(Combine Like Terms)
8x+−12=8x+−12
8x−12=8x−12
Subtract 8x from both sides.
8x−12−8x=8x−12−8x
−12=−12
Add 12 to both sides.
−12+12=−12+12
0=0
The real numbers are the only solution we can have.
Y=-x+9 is the correct answer
Answer:
-146, but I could be wrong, so wait till someone else answers
Step-by-step explanation:
Answer:
52/145 ≈ 0.359 = 35.9%
