Answer:
1 4/25 - 3/5, or 29/25 - 3/5, or 
it doesn't really matter they all mean the same
Step-by-step explanation:
1 2/5m - 3/5(2/5m + 1)
multiply first
1 2/5m - 6/25m - 3/5
multiply 1 2/5 only so the denominator is 25 as we can't simplify 6/25, it's so we can add them together, we can't add 3/5 tho bc it's a different term so there's no need to multiply that.
1 10/25m - 6/25m - 3/5
add/subtract
1 4/25m - 3/5
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
Answer:
543
Step-by-step explanation:
Well that's easy it basically tells you all you gotta do is plug in the numbers
"E" is what you're trying to find out so you don't know that one it stays the same.
"S" is the amount of money she started with and it says she started with $500
And then she has $274 less than she started with.
E = 500 - 274
E= 226
She is left with $226 after her weekend at the beach.
