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
.
Answer:
the answer us about .53 per hour
Step-by-step explanation:
You just divide 14.25 by 24
8x+6y=10
6y=10-8x
y=(10-8x)/6
If an is a5
and
an-1 is a4
then using your recursive formula for an arithmetic sequence
an=an-1 +d
then
a5=a4+d
now, a4 =6 and common difference "d" is d=-11
hence
a5=6 -11
6-11= -5
any questions?
