Answer:
4 bars
Step-by-step explanation:
12 divided by 2= 6
6-2=4
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:
x = 4
Step-by-step explanation:
9(x - 2) = 18
9 * x = 9x
9 * -2 = -18
9x - 18 = 18
+18 +18
9x - 18 + 18 = 9x
18 + 18 = 36
9x = 36
---- -----
9 9
9x/9 = x
36/9 = 4
x = 4
