Step-by-step explanation:
There are 187 seniors.
Of those 187, there are 45 who have black eyes.
Of those 45 black eyes, 20 of them are female.

First to Answer:
The answer is 2 1/4
Have a great day!
Work:
9 divided by 4 is 2.25.
0.25 is equivalent to 1/4 and 2.00 is equivalent to 2.
put those together and you get 2 1/4.
b² - 121
(b +11)(b - 11)
b² - 11b + 11b - 121
2x * x : 2 = 400
x = 20 (side x)
20 * 2 = 80 (side 2x)
√80²+20²=
82.46 (side H)
3x + 42-34
3x+8 the answer is 3x+42-34 = 3x +8
