The distance traveled by the balloon in every minute makes an arithmetic sequence with a first term equal to 40 ft and common difference equal to 20. The nth term of an arithmetic sequence is calculated by,
an = a1 + (n - 1) x d
Substituting,
an = 40 + (15 - 1) x 20 = 320
Thus, the answer is letter B. 320 feet.
Answer:
The System of linear equations are:

Step-by-step explanation:
Here, a represents the number of 2-points and b represent the number of 3-point basket.
As per the statement:
The basketball team scored 82 points from 2- points and 3-points baskets.
⇒
It is also given that: They make 38 baskets altogether.
⇒
therefore, the system of linear equations are:
