80

Explanation:

-12 increased by half of a number is 28. What is the number?

-12 + 1/2x = 28

1/2x = 28 + 12

1/2x = 40

x = 40 * 2

x = 80

----------------------

check

-12+ 1/2 * 80 = 28

-12 + 40 = 28

28 = 28

this answer and the other answer are good

Answer 2

80

Explanation:

28-28=0

0-12= -12

28+12 = 40

28-40 = -12

40 is the increase

40 is half of 80

So, the answer is 80

To check: -12 + 40 (half of a number; 80) = 28
