5 is a whole number so keep it as 5 then 4 is in the tenths place so that means have ten for the denominator so 5 and 4/10 is the mixed number then simplified to 5 and 2/5
Answer:
3
Step-by-step explanation:
3x+2y=12
5x-7=y
3x+2(5x-7)=12
3x+10x-14=12
13x=12+14
13x=26
x=2
3(2)+2y=12
6+2y=12
2y=12-6
y=6/2
y=3

We get tne n-th term with: tn=1/3tn-1
We know that the first term is t1=81, so 81=1/3t*1-1
81=1/3t-1
82=1/3t
82*3t=1
3t=1/82
t=1/82*3=1/246
The second term is: 1/
2*(1/246)*2)-1
We get the third term by replacing n with 3 and so on...
