Alex is making scrapbooks for friends he wants to decorate each grab book with 1/6 yard of ribbon he has a spool with 5/6 yards of ribbon left on it he plans use all the ribbon on the spool how many scrapbooks can alex decorate

  5

Step-by-step explanation:

In terms of ribbon, Alex intends to satisfy the equation ...

  (1/6 yard/scrapbook) × (N scrapbooks) = 5/6 yards

Dividing by the coefficient of N, we have ...

  N = (5/6)/(1/6) = 5 . . . . . . . units of yards and scrapbooks cancel

Alex can decorate 5 scrapbooks.

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
