Both distances 3966 and 4746 were done in 6 hours, so the speeds are:
speed against wind = 3966/6=661 km/h (difference of airplane and wind)
speed with wind = 4746/6=791 km/h (sum of airplane and wind)
The speed of airplane is greater than that of the wind, so this is a sum and difference problem.
Greater speed (plane) = (sum+difference)/2=(791+661)/2=726 km/h
Lesser speed (wind) = (sum-difference)/2 = (791-661)/2 = 65 km/h
Answer:
i think it is no
Step-by-step explanation:
because 1+4=5
and girls are one so i think it is 1/5
hopefully i am right
Notice that
so on the left side, a factor of <em>x</em> - 7 in the numerator and denominator can cancel
But we can only cancel them out as long as <em>x</em> ≠ 7 (because otherwise we'd have the indeterminate form 0/0 on the left side).
So, the equation is true for all <em>x</em> <u>except</u> <em>x</em> = 7. In set notation,
In interval notation,

4/2
