Question 1 Fill in the blank question.
The sum of two numbers is 20.5. Their difference is 6.5. Find the two numbers.

Part A

Write a system of equations that represents the situation.

x+y=

x−y=

Part B

Solve the system of equations. Express the coordinates as decimals if necessary.

( , )

Part C

Interpret the solution.

The greater number is

and the lesser number is

x = 13.5

y = 7

(13.5,7)

what the solution means is that (13.5,7) would be the point at which the two lines, x+y=20.5 and x-y=6.5, would intersect

Step-by-step explanation:

x + y = 20.5

x - y = 6.5

if we add the two equations we get:

2x = 27

x = 13.5

y = 20.5 - 13.5

y = 7

solution as an ordered pair:

(13.5,7)

What the solution means is that (13.5,7) would be the point at which the two lines, x+y=20.5 and x-y=6.5, would intersect

the answer is  

c.

90.0π cm^2

hope you got it.

if i knew id you bro,, my bad
