A number can be represented by n. So n/15≤450 then multiply both sides by 15 to get n by itself n≤6,750

Answer:
- 508
Step-by-step explanation:
The n th term of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 28 and d = - 34 - (- 28) = - 34 + 28 = - 6, thus
= - 28 + (- 6 × 80) = - 28 - 480 = - 508
3(b+6) = 3*b + 3*6 = 3b + 18
