Question

What should be added to the sum of (-64) and 15 to make it equal to the sum of (-25) and (-10)​

Answer 1

Answer:

Precipitation deficiency

Precipitation deficiencyDroughts occur mainly in areas where normal levels of rainfall are, in themselves, low. If these factors do not support precipitation volumes sufficiently to reach the surface over a sufficient time, the result is a drought.

Answer 2

Answer:

Let the no. added be x

Therefore, acc. to question,

x+(-64+15) = -25+(-10)

x-49= -35

x = -35+49

x = 14

Therefore, the no. added will be 14
