So you first make 1 7/9 into 16/9
then you do 16/9 - 4/9 which equals to 12/9 then you simplify and get 4/3 then simplify again into 1 1/3
N/4.3 = 9.4
4.3 × n/4 = 9.4 × 4.3
n = 40.42
Answer:
Step-by-step explanation:
common ratio=18/-3=-108/18=-6, a=-3
sn=a(r^n-1)(r-1)
sn=-3((-6)^n-1)(-6-1)
sn=-3(-6)^8-1)/(-7)
s8=-3(1679615)/(-7)
s8=719836
Answer:
994
Step-by-step explanation:
2(s+t)= 10
10^3= 1.000
1.000-6= 994
