The key is to find the first term a(1) and the difference d.
in an arithmetic sequence, the nth term is the first term +(n-1)d
the firs three terms: a(1), a(1)+d, a(1)+2d
the next three terms: a(1)+3d, a(1)+4d, a(1)+5d,
a(1) + a(1)+d +a(1)+2d=108
a(1)+3d + a(1)+4d + a(1)+5d=183
subtract the first equation from the second equation: 9d=75, d=75/9=25/3
Plug d=25/3 in the first equation to find a(1): a(1)=83/3
the 11th term is: a(1)+(25/3)(11-1)=83/3 +250/3=111

Answer:
2 Minutes
Step-by-step explanation:
the first ratio is 5:10 since it is easier to work with big numbers let's start by multiplying it by 2 to get something
Now we have 10:20 we can divide this by 10 and get the ratio 1:2
1:2 equals 1 mile:2 minutes which is 1 mile in 2 minutes!
Have a nice day and I hope this helps!
Answer:
I think answer number 1 and number 4
Step-by-step explanation:
to find the perimeter you add all the sides together, there are 4 sides in the square so it will be 2+2+2+2 which will give you 8 and you can also multiply 2 by the 4 sides which will also give you 8
If x=10 than f(x)=1 because 2+8=10/10 =1
