Total students = 15+21=36, so the probability of choosing a girl is 21/36, which reduces to 7/12.
Total freshmen = 12+15=27, so the probability of choosing a freshman is 27/36, which reduces to 3/4.
We will check if y and 60cm are parallel.
If the lengths 28cm, 56cm and 15cm, 30cm are in proportion, then y and the segment 60cm are parallel.

OK. We know: y and 60cm are parallel. Therefore we have equation:

<h3>Answer: y = 90 cm.</h3>
twenty four divisible by six, if that what u meant . or 24÷6
The answer is the third one.
(7,0)
The two numbers in each column have to add to 23
So under 7 you write 16, above 4 you write 19, etc
The rule will say x + y = 23
