The seats at a local baseball stadium are arranged so that each row has 5 more seat than the row in front of it. If there are fo ur seats in the first row, how many total seats are in the first 24 rows
1 answer:
You would do an arithmetic sequence use A1 +(n-1)d to calculate number of seats in the last row An = 4+(24-1)5 An = 4 + (23)(5) An = 4 + 115 An = 119 seats in the last row now use a sum sequence to find total number of seats Sn = n(a1 + an)/2 Sn = 24(4+119)/2 Sn = 24(123) /2 Sn = 1476 total seats

So 1/12 of some number will get us 18 inches right?
We must divide 18 by 1/12 to get that number, which is the same thing as 18*12 which is 216. So the actual length of the car is 216 inches.
Hope this made sense!
The coefficient of the variable: 26=9x, would be 9.
