The sum of two numbers is 20.5 and the difference of the same two numbers is 6.5. Find the two numbers. *​

13.5 and 7

Step-by-step explanation:

x + y = 20.5

x - y = 6.5

Hence,

x = 20.5 - y

20.5 - 2y = 6.5

Hence,

2y = 14

y = 7

and x = 20.5 - y = 20.5 - 7 = 13.5

step-by-step explanation:

if you meant, "on the way from (3, 2) to (3, 14):

x does not change; y increases by 12.

ensure that you have copied down this problem correctly.   .

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.
