X is a number from the set [3,5,6] and y is a number from the set [4,7,8,9]. If xz/y is an integer and z is a positive integer,
UNO [17]

The smallest possible value of z is the denominator of the reduced fraction x/y. We note the prime factors of the members of set y are

... 2², 7, 2³, 3²

so if there are any even members of set x, the fraction can be reduced to something divided by 2. The number 6 in set x is even, so we have

... 6z/4 = 6·2/4 = 3 (an integer) when z=2

The lowest possible value of z is ...

... B) 2

A total of 725 tickets were sold for the school play. They were either adult tickets or student tickets. There were 75 more stud
Pavel [41]
X= number of student tickets soldx+75= number of adult tickets sold
Add the number of student and adult tickets together to total 725 tickets

x + (x + 75)= 725
combine like terms
2x + 75= 725subtract 75 from both sides
2x= 650divide both sides by 2
x= 325 adult tickets

x + 75= 400 student tickets

ANSWER: There were 325 adult tickets sold
Hope this helps!  :)

Help??I don't remember the way to do this i know i'm dumb
timofeeve [1]
So you just have to subtract 15 - 7.5 = 7.5
because 7 x 2=14
and .5 +.5 = 1
and 14 + 1= 15
