Step-by-step explanation:
i did the math
Following the generalized form that you wrote, you know that a negative exponent sends its base to the denominator (or numerator if it's in the denominator already). Or to put it formally as you wrote it, for any nonzero real number a and natural number n, <span>the negative rule of exponents states that </span>

Answer:
15
Step-by-step explanation:
Sum of 'n' terms formula is given by:-
s=n/2(2a+(n-1)d)
s=13/2[2xa+(13-1)5]
s=13/2(2xa+12x5)
s=13/2(2a+60)
585=13/2(2a+60)
585 x (2/13) = 2a + 60
90 = 2a + 60
90-60 = 2a
30 = 2a
a = 15
C)5.40
The answer is $5.40 because 5 x 8=40 and the sales tax is 8% so you just add 2 decimal places so 5.00 + .40 =5.40.
P.S. You put the answer in your question.
$675.00 - $530.00 = $145.00
$145.00 - $200.00 = $55.00 negative balance, amount short.
$55.00 + 340.00 = $285.00 positive balance after deposit.
$285.00 - $29.00 = $256.00 new balance
Daniel has a new balance of $256.00
