What is the answer?<br> xy = 30<br> and x + y = 18
drek231 [11]

from second equation y = 18-x so:-

x(18 - x) = 30

x^2 - 18x + 30 = 0

x = 16.14, 1.86


when x = 16.14 y = 18-16.14 = 1.86

when x = 1.86, y = 16.14


so one variable = 16.14 and the other = 1.86 Answer

<h2>Verbal Phrase to Mathematical Phrase</h2><h3>Answer:</h3>

A group of 5 men are meeting for lunch.
Sladkaya [172]

Tile:

<h2>See the explanation.</h2>

Step-by-step explanation:

(a)

There were total 5 men wearing coats.

5 coats can be returned to 5 men in 5! = 120 ways.

The coats can be returned to the accurate persons only in 1 way.

Hence, the probability that each man gets the correct coat is \frac{1}{120}.

(b)

At the time of returning the first coat, the hostess will have 5 choices and for the second she will have 4 choices.

Hence, in 5\times4 = 20 ways the hostess can return the 2 coats.

There is only 1 possible case that each of the coats will return to the correct owner.

Hence, the required probability is \frac{1}{20}.
