Joe has a bag of 24 pieces of candy. He gives 1/8 of them to a friend, 1/7 of what is left to another friend. How many pieces does he have
left?

18 pieces.

Step-by-step explanation:

1/8 of 24 is 3.

24 - 3 = 21, that's how much he has left after giving it to the first friend.

1/7 of 21 is also 3.

21 - 3 = 18, there's your answer.

18

Step-by-step explanation:

1/8 of 24 is 3 = 21

1/7 of 21 is 3 = 18

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.
