Answer: -1>n
Step-by-step explanation:1) combine like terms (-5n+2n=-3n) so you have 3<-3n then you divide -3 on both sides and because it’s a negative you flip the sign so you end up with -1>n
Answer:
86ft²
Step-by-step explanation:
3x2/2=3
3x2/6=3
10x2.5=25
10x2.5=25
3x10=30
30+25+25+3+3=86
If each years cumulate an increase of 1100 dollars, then the cost after 22 years will be the base cost (27000) plus 22 increases (22*1100), for a total of

This relates to arithmetic series as follows: a series is arithmetic if, given a starting element
, every next element is given by adding a fixed number, called common difference,
. So, the first terms are
So, you can see that the element
is obtained by adding n times the common ratio to the starting element.
Since the element
represents the cost after n years, we are interested in the element

As we had already calculated.
2/8 or 1/4, you would divide 4/16 by 2 to find the 8 slices.
