The answer is 6, 4 divided by 2/3 =6
if you need to show your work just multiply by the reciprocal :)
Answer:
1 solution
Step-by-step explanation:
3(2x-7)=9
dustribute: (3)(2)+(3)(-7x)=9
6+-21x=9
subtract 6 from both sides: -21x=3
Divide both sides by -21: x=-1/7
so your 1 solution is x = - 1/7
The way you typed it, it seems like you need to know the total number of beads, which would be 300
The answer to the question
Let the speed of the water current be v.
total travel time = time to go upstream + time to return downstream to the starting point
Hence, 8 = time in hours = 6 / (4-v) + 6 / (4 +v) = 6*8/(16-v^2)
Hence, 16 - v^2 = 6, or v^2 = 10 or v = √10 miles / hour
