Find the value of two numbers if their sum is 16 and their difference is 2.4
Verdich [7]

Lets x and y are the value of two numbers.

x + y = 16

x - y = 2.4

If x + y = 16 then x = 16 - y

Substitute x = 16 - y into x - y = 2.4

16 - y - y = 2.4

16 - 2y = 2.4

2y = 13.6

 y = 6.8

x = 16 - y

x = 16 - 6.8

x = 9.2

Answer:

The value of two numbers are 9.2 and 6.8

What is the answer help im having a mental breakdown
Serggg [28]
So if the greatest common factor between 28 and 24 is 4, then you should have 4(7 + 6). If you don’t think it’s right:
4(7 + 6) = 4 x 13 = 52
28 + 24 = 52
