Answer:

34 and 19.

Step-by-step explanation:

Since the sum of the two numbers is 53, x+y=53. Since the difference is 15, x-y=15.

Adding x+y=53

and x-y=15,

The ys cancel, leaving 2x=68, or x=34. Therefore, 34-y=15, or y=19.

Answer:

34 and 19.

Step-by-step explanation:

If the numbers are x and y:

x + y = 53

x - y = 15 Add the 2 equations:

2x + y - y = 68

2x = 68

x = 34.

As they add up to 53:

y = 53 - 34 = 19.

Answer by JKismyhusbandbae: B) –10.6

Work/Explanation: Since the sequence slowly gets smaller, it is likely that each term is something added to (subtracted from) the previous term. To get from –7.9 to –8.8, it appears that the first has had –0.9 added to it. Continue adding –0.9 to get that the fourth term is –10.6.

The 8 foot diameter circular table has a 4 foot wide extension. What is the total area with the extension? How does the area com

Ann [662]

To compare the areas of the table without the extension and the table with the extension, you would need to find the areas of both. See the attached page for the area of the table with the extension. To compare this to a table with a diameter of 10 ft, you need to calculate the area of the table that has a diameter of 10 feet. See the attached page for this information as well. When you're done make a comparison statement giving both pieces of information in your answer.
