Answer:
sn = d/2·n^2 + (a - d/2)·n
sn = (-4)/2·n^2 + (19 - (-4)/2)·n = -441
- 2·n^2 + 21·n = -441
- 2·n^2 + 21·n + 441 = 0
n^2 - 21/2·n - 441/2 = 0
use pq-Formula
n = -10.5 ∨ n = 21
only n = 21 makes sense. So n = 21 is the correct answer.
Hello!
The thing you have to do here is get the miles per hour, which means we have to multiply the 1/15 by 15 to get 15/15, which is 1.
When you do this, you should also multiply the 3/5 miles by 15, which is 45/5 or 9.
This means the rate is 9 miles per hour

Answer:
Step-by-step explanation:
watermelon=w
cantaloupe=c
3w+2c=32 x3 9w+6c=96
4w+3c=44 x2 8w+6c=88
(9w+6c) - (8w+6c) =
96-88=
c=8
canteloupe is 8 pounds
3w+2(8)=32
3w+16=32
3w=16
w=5 1/3 pounds
watermelon is 5 1/3 pounds
2(5 1/3)+8=
10 2/3+8=
18 2/3 pounds
