To mail a package, the rate is x cents for the first pound and y cents for each additional pound, where x>y. Two packages wei
horrorfan [7]

Answer:

Option A) Combined, with a saving of x-y cents      

Step-by-step explanation:

We are given the following in the question:

The rate to mail a package is x cents for first pound and y cents for each additional pound.

x>y

Weights of packages =

3 pounds and 5 pounds

Cost of combined package:

Total weight = 8 pounds

C\text{(combined)} = x + 7y

Cost of sending separately:

C\text{(separated)} = (x + 2y) + (x + 4y) = 2x + 6y

Difference between cost of sending the packages separately and combined

C\text{(separated)}-C\text{(combined)} \\=2x + 6y-(x+7y)\\=(x-y)\text{ cents}

Thus, sending the packages combined is a cheaper method with a saving of (x-y) cents

Thus, the correct answer is:

Option A) Combined, with a saving of (x-y) cents

Solve for x<br><br><br><br> Please help
adoni [48]

Step-by-step explanation:

\frac{x}{x + x + 6}  =  \frac{9}{30}

\frac{x}{2x + 6}  =  \frac{9}{30}

30x = 9(2x+6)

30x = 18x+54

30x-18x = 54

12x = 54

x = 54/12

= 27/6
