The correct answer is: 9 + c = 12
Further explanation:
Given
c = number of babies whose eyes are closed
So,
If the total number of babies are 12 then the sum of babies with eyes closed and eyes opened should be equal to 12.
As c is the number of babies with eyes closed and 9 is the number of babies with eyes opened then,

The equation can be used to find the number of babies whose eyes are open

Three babies have their eyes closed in the photograph.

Answer: huh
Step-by-step explanation:
To measure the length or height of something which is a little smaller we prefer to use centimeters.
Lets look at each of the options one by one.
1. Distance between Philadelphia and New York , it is roughly about 94.1 miles which will be way too big of a number if converted in to centimeters (it will be 15000000 cm).
2. Length of a paperclip, this is something that is a considerable length and can be measured in centimeters. Usually a paper clip measures around 3-4 centimeters.
3. Height of a standard ceiling, while constructing something we measure height or length or the width of a floor in feet.
4. Yearly increase in a child's height, that can be measured in centimeters but often we use inches.
5. Width of a swimming pool is also conventionally measured in feet.
So, it is the length of a paperclip and the yearly increase in a height of a child are two things that can be measured in centimeters.
