The sum of two numbers is 12. The difference of the same two numbers is −4. Find the two numbers.

Butoxors [25]

Answer:

4 and 8

Step-by-step explanation:

Let 'a' represent one of the numbers. Then the other is 12-a, and their difference is ...

a - (12-a) = -4

2a = 8 . . . . add 12

a = 4 . . . . . divide by 2

12-a = 8 . . . . find the other number

The two numbers are 4 and 8.

Answer:

Step-by-step explanation:

angle CHA is equal to angle HGB because they are alternate interior angles.

This means that angles CHA and AGH are supplementary, add up to 180 degrees.

So, 5x + x + 12 =180

6x = 168

x = 28

<CHG = x + 12 = 28 + 12 = 40
