Answer:
= - 3n - 3
Step-by-step explanation:
The nth term of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 6 and d = a₂ - a₁ = - 9 - (- 6) = - 9 + 6 = - 3 , then
= - 6 - 3(n - 1) = - 6 - 3n + 3 = - 3n - 3
Yes, Torri does have enough.
How to find the answer:
Find the decimal of 7% which is 0.07
Multiply 0.07 times $18 which gives you 1.26
0.07 x 18 = 1.26
Add 1.26 to 18 which gives us 19.26
1.26 + 18 = 19.26
Our finale answer is 19.26
Torri has enough money to buy her dad the DVD.

Answer:
1 hour later , 21 pages read
Step-by-step explanation:
x hour later they will read the same number of pages
Tori: 16 + 5x
cora: 13 + 8x
16 + 5x = 13 + 8x
minus 5x each sides: 16 = 13 + 3x
minus 13 each sides: 3 = 3x
divide 3 each sides: x = 1
1 hour later both of them will read 16 + 5 x 1 = 21 pages
check cora: 13 + 8 x 1 = 21
