35 toes? 5 toes on each foot
35 divided by 5=7
7 feet…?
Answer:
-9
Step-by-step explanation:
2040 = n/2(20+(n-1)4)
4080 = n(20+4n-4)
4080= 20n +4n^2 -4n
1020 = 4n + n^2
n^2 +4n -1020 =0
use common formula (can't write out so just look at answers. sorry)
which gives answers of n=-34 and n=30. since n can only be positive, n=30 so there are 30 rows. I liked that challenge
15 into thirds would be 15 divided by three. This would be 5. If you take 14 and divide it in half you get 7. Then subtract 5 from 7 and you get 2. The answer is 2.
