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:

Step-by-step explanation:
Given
Represent Boys with B and Girls with G


Required
Find the probability or having 1 boy 2 girls
Since the order is not important, the probability is calculated as follows;

Substitute
for P(B) and P(G)



<em>Hence, the fractional probability is </em>

The formula for the hypotenuse of a triangle is:
[a squared] plus [b squared] = c squared
a and b represent the two sides of the triangle.
You would have to square 8 and 4, add them, then take the square root of it to find the length of the hypotenuse.
<h2>The first equation is correct.</h2>
Answer:
C.
The equation that represents this situation is -3x = 21. The second number is -7.
Step-by-step explanation:
Answer:
The length of XZ is 15 miles.
Step-by-step explanation:
Use Pythagorean Theorem to solve this problem
9² + 12² = C² Simplify the squares
81 + 144 = C² Add on the left side
225 = C² Take the square root of both sides
15 = C
