I already answered it on one of your posts with the same question, but here I'll tell you again :)
<span>Okay so first set up the equation(s) for this situation. In this case, you need two equations:
B=3/4A (In which B= Benjamin and A=Ann)
S=2B (In which S= Siti and B= Benjamin)
Now first solve for the first equation where you can plug in A for 35kg:
B=3/A
B=3/4*35
B=26.25
Now you can use that value and use it for the second equation. Plug in B with 26.25:
S=2B
S=2*26.25
S=52.5
So Siti has a mass of 52.5 kg</span>
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:
3.20 per yard because there are 36inches in a yard 36×0.5=5.40
