Answer:
96
Step-by-step explanation:
commom difference = d
a₆ + a₇ = 16
a₅ + a₈ = (a₆ - d) + (a₇ + d) = a₆ + a₇ = 16
a₄ + a₉ = (a₆ - 2d) + (a₇ + 2d) = a₆ + a₇ = 16
Similarly,
a₃ + a₁₀ = 16, a₂ + a₁₁ = 16, a₁ + a₁₂ = 16
so
a₁ + a₂ + ... + a₁₁ + a₁₂ = 6 x 16 = 96
Answer:

Step-by-step explanation:
49 minutes = 27 price
D=62*
triangles=180*
use the equation 90+28+d=180
Answer:
9572 visitors
Step-by-step explanation:
This is exponential: y=ab
a = initial value
b = growth rate
It will grow by 5% each year but also keep the same amount as last year (100% of last year's visitors)
a = 7500
b = 1.05

Plug in x=5
9572.111719 = 9572 visitors
