Answer:
4b, b, and 9b are like terms
Step-by-step explanation:
9 - 6 + 4 - 8/3 ..,
geometric series a(n) = a1r^(n-1)
r = a(n+1)/a(n)
-6/9 = -2/3
4/-6 = -2/3
-8/3/4 = -2/3
so r = -2/3 and a1 = 9
Sn = a1(1-r^n)/(1-r) = 9(1-(-2/3)^n)/(1-(-2/3))
n is infinite Sn = 9/(5/3) = 27/5
Answer:
43/100
Step-by-step explanation:
Decimals are easier to be put into if the denominator is 100.
If we half the numerator and denominator we get 38.5/100
if 1=0.01
38.5 = 0.385
hope that helps! :)
