Each pound costs 2.40,
to check this 2.40 * 5 = 12
so 2.40 * 7 = 16.80
Answer: 16.80
Omar can make 14 whole dumplings. You change 2 3/4 cups to an improper fraction ( multiply the denominator and add the numerator ) and you get 11/4. Since you need 3/16 cups for one dumpling you have to find the greatest common denominator which is 16. You multiply 4 by 11 to get the numerator and end up with 44/16. Since you need 3/16 for one whole dumping you divide 44 by 3 and get 14.6 repeating. You cannot have a fraction of a dumpling so you round down and get the answer 14.
309x+489(11-x)=4299
Solve for x
X=6 for 309
11-6=5 for 489
Answer:

Step-by-step explanation:
The two equations given represent two straight lines in 2-D graph.
The two lines will not intersect if they are parallel.
Hence the two equations will not have solution if the lines are parallel and not coincident.
The condition for 2 lines given by the equations :
ax+by+c=0
dx+ey+f=0 to be parallel but not coincident is:

here a=2 b=-3k c=-1 d=4 e=k+2 f=-5

But also:

Hence the value of k is -2/7.
