Answer:
A similar problem to yours is attached in the picture below. We adjust the data of the problem in the picture to fit your question.
The answer is (3/4)*(3/4)*(1/3) = 3/16 of the girls in the class have long brown hair and green eyes
Step-by-step explanation:
As every condition must contain the set we are studying, we are talking about and AND condition, and thus we need to multiply each term to get the correct result.
3/4 * (3/4) * (1/3) = 3/16
To find this answer, we subtract each of the like terms in the equation. 3x and 3x are like terms, -4y and 2y are like terms, and 7 and -5 are like terms. Now we subtract. 3x - 3x is 0, -4y - 2y is -6y, and 7 - (-5) is 12. That means that the result is -6y = 12, or B.

Answer: 40 inches</h3>
==========================================================
Explanation:
- x = first piece
- 2x = second piece, since its twice as long as the first
- 5x = third piece, since its five time as long as the first
x is some positive real number, and the units of each are in inches.
Add up the smaller pieces and we should get 64 inches back again
x+2x+5x = 64
8x = 64
x = 64/8
x = 8
The first piece is 8 inches long.
2x = 2*8 = 16 is the length of the second piece (in inches)
The third piece is 40 inches because 5x = 5*8 = 40
--------
Summary:
first = 8 inches
second = 16 inches
third = 40 inches
Check: 8+16+40 = 64, which confirms the answer
