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.
Weights of packages =
3 pounds and 5 pounds
Cost of combined package:
Total weight = 8 pounds
Cost of sending separately:
Difference between cost of sending the packages separately and combined
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
y/5 = x
multiply by 5 on each sides
y = 5x
There you go! I really hope this helped, if there's anything just let me know! :)

Answer: 2730 tiles (Approx)
Step-by-step explanation:
Since, The side length of each side = 25
According to the question the shape of the tile is square.
Thus, the area of one tile = 25 × 25 = 625 
Also, we need to tile a kitchen measuring 102 ft. by 18 ft
Thus, the area of the room in which we have to tile = 102 × 18 = 1836 
= 1836×30.48 × 30.48 = 1705699.8144
Thus, the total number of the tiles = the area of the room in which we have to tile / the area of one tile = 
Since, we must take 2730 tiles to tile the kitchen.
The question is asking us to determine the number of rows in which Sam can arrange his 12 black and white and 18 color photos. Sam wants to put them in the equal rows so that each row has either black and white photos only or color photos only. We have to find the GCF ( the Greatest Common Factor ) of 18 and 12. GCF ( 18, 12 ) = 6. So there should be 6 photos in each row if they have to be equal ( the equal number of photos in every row ). 18 = 6 * 3 and 12 = 6 * 2. Therefore the number of the rows is : 3 + 2 = 5. Answer: Sam can arrange his photos in 5 rows<span>. </span>
