Question

Which equation models the problem below if c represents the number of babies whose eyes are closed? There are 12 babies in a photograph, and 9 of them have their eyes open. How many babies have their eyes closed? 9 – c = 12 12 + c = 9 c – 9 = 12 9 + c = 12

Answer 1

`9+c=12`

Explanation:

Given there are 12 babies in a photograph ,Out of which 9 babies have their eyes open .So by intuition one can say that the other babies have their eyes closed.Let the number of babies with their eyes closed be "c". Then

Total number of babies=12

number of babies with their eyes open=9

number of babies with their eyes closed=c

Total number of babies= number of babies with their eyes open + number of babies with their eyes closed.

`12=9+c`
