Answer:
Step-by-step explanation:
If we expand 4(3+x), we get (4*3)+(4*x).
Then we do 4*3 to get 12 and 4*x to get 4x
(3+3+3+3) is the same thing as 4*3, because we are adding 3 together 4 times. (3+3+3+3) gives us 12 as well, since they are the same thing.
(x+x+x+x) is the same thing because we are adding x together 4 times, which is the same thing as (4*x). (x+x+x+x) gives us 4x as well.
Hope this helps.
Answer:
( 3n-8)
Step-by-step explanation:
so the given sequence is AP
where common difference is +3
nth term for this AP will be
(-5)+(n-1).(3) = 3n-8
You see, start at 1 and 1/3, and since the denominator is different from 1/6, find an equivalent fraction. Which is 1 and 2/6, now subtract 1/6 from that number. The answer is 1 and 1/6
It depends how much she begins with but if she doesn’t begin with any then it’d be 2.5
