Answer:
Possible lengths of the silk fibre 'x' are 100, 75, 60, 50 and 30 yards respectively.
Step-by-step explanation:
Let the length of the silk fiber = x yards.
Let the number of silk fibres = a.
It is given that the silk fibers between 3 to 10 yards are combined to form a silk thread of 300 yards.
So, we get the equation,
, where 
i.e.
, 
So, the possible values of 'a' are 3, 4, 5, 6 an 10.
Thus, the possible lengths of the silk fibre 'x' are 100, 75, 60, 50 and 30 yards respectively.
yes because you have to pay more it's tricky
Answer:
No, not correct.
Step-by-step explanation:
Note that 8 * 4.3 can be broken up as follows:
8 * (4 + 0.3)
and that 4*8 =32, and that 0.3(8) = 2.4 (not 0.24).
Then 8 * (4 + 0.3) becomes 32 + 2.4 = 34.4
