P = IRT
T=P/(IR)
hope helped
If it is division then it would be
which would be false but since I could not determine if it is division or multiplying
if multiplying it would be
which would be true
WHERE IS THE PIC TO SEE IT
I AM NOT ABLE TO SEE
Let H represent hardcover
let P represent paperback
H + P = 20
H = P + 10
sub in H into the first eq’n
(P + 10) + P = 20
2P + 10 = 20
2P = 10
P = 5
sub P into eq’n 2
H + (5) = 20
H = 15
therefore there are 5 paperback books and 15 hardcover
It's an arithmetic sequence:
The explicit rule:
Substitute:
<h3>Answer: f(n) = 6n - 2</h3>
