Aproofreader can read 200 pages one in 6 hours and one in 9 hours. can both meet a 3-hour deadline to work to read the 200 pages?

Proofreader 1 :

6 hours = 200 pages

1 hour = 200 ÷ 6 = 33 1/3 pages

Proofreader 2:

9 hours = 200 pages

1 hour = 200 ÷ 9 = 22 2/9 pages

Proofreader 1 + Proofreader 2:

1 hour = 33 1/3 + 22 2/9 = 55 5/9

3 hours = 55 5/9 x 3 = 166 2/3

They can read 166 2/3 in 3 hours.

No, they cannot meet the deadline to read 200 pages in 3 hours.

mean, 40.6

step-by-step explanation:

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.
