Given:
40 pages in 1.6 minutes
40 / 1.6 = 25 pages per minute
25 x 5 minutes = 125 pages
40 / 1.6 = x / 5
40*5 = 1.6x
200 = 1.6x
200/1.6 = x
125 = x pages
25 : 1 = 150 : x
25x = 150
x = 150/25
x = 6 minutes
I'm assuming that you are talking about sequences <3
In the context of a recursive formula where we have "n-1" in sub-index of "a", you can think of "a" as the previous term in the sequence. In the context of an explicit formula like "-5+2(n-1)" "n-1" represents how many times we need to add 2 to the first term to get the nth term.
Dw if you don't understand, sequences and functions isn't an easy topic
Answer:
Below.
Step-by-step explanation:
= 
The multiplicative inverse is basically the opposite reciprocal.
In this case, it is 16

Answer: 165/11 =
(3 × 5 × 11)/11 =
((3 × 5 × 11) ÷ 11) / (11 ÷ 11) =
(3 × 5)/1 =
15/1 =
15
