18.5 you’d add 2.5 to 16 since 12.5 - 10 is 2.5 hope this helps
Answer:
Step-by-step explanation:
<u>This is an AP with:</u>
- The first term a₁ = 12
- Common difference d = 3
- Number of terms n = 40
<u>Number of the seats:</u>
- Sₙ = 1/2*n(a₁ + aₙ) = 1/2n(2a₁ + (n - 1)d)
- S₄₀ = 1/2*40(12*2 + 39*3) = 2820 seats
<u>Formula of nth term:</u>
- aₙ = a₁ + (n - 1)d
- aₙ = 12 + (n - 1)*3 = 12 + 3n - 3 = 3n + 9
- aₙ = 3n + 9
Answer:
The answer is true
Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).

26 is probably the answer
15% = 0.15
<span>8 = 0.15x </span>
<span>8/0.15 = x </span>
<span>x = 53.33 or 160/3</span>
