A. X = 2
what you do is divide each side by the coefficient of x (3.2) to get rid of it on the left, and simplify the right: 2.
Answer:
0.8
Step-by-step explanation:
Answer:
40
Step-by-step explanation:
2/8 = 10/40
3/5 = 24/40
Fron the table given:
A3 = 112,
A8 = - 3,584
An = A1 *r ^ (n-1)
=> A3 = A1 (r^2) = 112
A8 = A1(r^7) = - 3,584
=> - 3584 / 112 = (r^7) / (r^2)
=> (r^5) = - 32
=> r = - 2
=> A1 (- 2)^2 = 112
=> A1 = 112 / 4 = 28
Answer: a1 = 28
If you break it down it goes to 2 laps every 5 minutes. So any set that follows this "pattern" would be proportional
