A total of 640 tickets were sold for the school play. They were either adult tickets or student tickets. There were 60 fewer student tickets sold than adult tickets. How many adult tickets were sold? NO LINKS

350 adult tickets were sold

Step-by-step explanation:

Let x represent the number of adult tickets sold.

Since there were 60 fewer student tickets sold than adult tickets, the number of student tickets sold can be represented by x - 60

Create an equation that sets up these terms equal to 640, then solve for x:

(x) + (x - 60) = 640

2x - 60 = 640

2x = 700

x = 350

So, 350 adult tickets were sold

the correct answer is 45x

9×5=45 then add the x

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
