x+y=92-> -2x-2y =-184 if you multiply by (-2)
x/5+y/2=34->2x+5y=340 if you multiply everything by 10.
3y=156 if you add the two equations together.
y=52 if you divide both sides by 3.
x=40 by subtraction from 92

Arrange the numbers in ascending order, and then take the mean of the fourth and fifth number.
The first prime numbers are 2, 3, 5, 7, 11, 13, 17, and 19. The first prime number is 2 and the fifth prime number is 11. The product of these two numbers is 2 x 11 = 22.
The counting numbers (1, 2 ,3, . . . ) are called cardinal numbers.
40 and 52

The ordinal numbers in English, followed by their French language equivalents: First: premier / première Second: deuxième (or second) Third: troixième Fourth: quatrième Fifth: cinquième Sixth: sixième Seventh: septième Eighth: huitième Ninth: neuvième Tenth: dixième Of note is the fact that, from one-fifth and beyond, the fractional numbers (such as one fifth) are identical to the corresponding ordinal numbers (such as fifth). Therefore, one-fifth is translated as "un cinquième".
Fifth is Ordinal (tellls the "order" something is in..i.e.first, second, etc.)
"Forth" does not belong because the other words are ordinal numbers (First, Second, Third, Fifth) while "Forth" is a misspelling of "Fourth."
Take a look on the numbers which are on the position of second, fourth, sixth(i.e. multiples of 2) and so on and take a look on the left and right side of these numbers, there is a relation:- First number is three times of second number and third number is four times of second number. The same relation is of fourth number with third and fifth. So, seventh number is 80 x 4 = 320.
The sum of four numbers equals 40: a+b+c+d=40 Those same four numbers, along with another number (e), give the set a mean of 12: (a+b+c+d+e)/5=12 Use these two facts to determine e as follows: (a+b+c+d+e)/5=12 a+b+c+d+e=60 (a+b+c+d)+e=60 40+e=60 e=20
A set of five numbers, the second to fifth of which are the same.
