Bob is x yrs old
Sister is x+6 yrs old
X+X+6=32
2X+6=32
2X=32-6
2X=26
2X/2=26/2
X=13
Bob is 13 yrs old
Sister is 13+6 yrs
= 19 yrs
13yrs+19yrs = 32 yrs
Now its 100% accurate

Answer:
0.2
Step-by-step explanation:
1/0.2 = 5
10-5 = 5
1/a = 5
a = 1/5
a = 0.2
Let the number of years of watching TV be
x
.
The number of years sleeping exceeds the number of years watching TV by
18
. This means that the number of years sleeping is higher than the number of years watching TV by
18
and can be represented by
（x+18).
The total time is 34
years. So we can form the following equation and solve for the required values:
x+(x+18)=34
x+x＋18=34
2x=34-18
2x=16
x=16/2
x=8
Thus, the number of years watching is 8
and the number of years sleeping is
8+18=26
.
