Answer:
Concept: Mathematical Sequences
- Let An be 99 a double digit multiple
- The sequence is finite.
- Finite= restricted and not bounded to positive infinity
- By that logic the last possible digit is 999999999999999999999999999999999999999999999
Assuming display of computer is at 100%
So increase by 20% = 120 (20/100 *100)
then 20% of 120 is: 20/100 * 120 = 24
So the display is now 120-24 = 96
Hope this helps!
It should be 3.5 if im correct
This could mean two things from how you’ve written it.
It could mean there is an X with the denominator 4 or it could mean there’s an X with the denominator 4-7.
I am going to work with the first one and assume the 7 is separate. Apologies if that is incorrect.
First, I would add the 7 to both sides.
This leaves you with X/4 = 4
Then, multiply both sides by 4, to get X on its own.
This leaves X=16, which is the answer.
