Answer:
5>t
Step-by-step explanation:
45 > 12t + 3(t -8) - 6 multiply 3 times t-8
1) 45 > 12t + 3t - 2 - 6 combine alike terms
2) 45 > 15t - 30 isolate the variable by adding 30
3) 75 > 15t divide by 15
4) 5 > t
If it moves 4.5 times a year and each time it moves 10 meters, one one year it moves 45 meters. Now we want 11 years, so that's 45 times 11 which would give you 495 meters in 11 years
