 # Exploring Equations

Directions: For each problem below, use the digits 1 to 9 at most one time each, to fill in the boxes to find the the greatest value for x that you can. ### Hint

Where should the 9 go or not go? Where should the 1 go or not go?

(1/8)x + 2 = 9 yields a solution of 56.

(1/9)x – 8 = 7 and (1/9)x – 7 = 8 both have a solution of 135.

## Similar Triangles And Slope

Directions: The three triangles on the line are similar. Using the digits 0 to 9 …

1. A student asked me about the value of x and since it’s on the page twice it implies they are the same value. Great activity!!
