Dan has started to cover a rectangular floor with tiles. the tiles are twice as long as they are wide. the fllor is 10 1/2 tiles wide and 18 1/2 tiles long. using this pattern, what is the total number of tiles dan will use to cover the floor?

Two positive integers are 3 units apart on a number line. their product is 108. which equation can be used to solve for m, the greater integer? m(m – 3) = 108 m(m + 3) = 108 (m + 3)(m – 3) = 108 (m – 12)(m – 9) = 108

Asmall business produces and sells balls. the fixed costs are $20 and each ball costs $4.32 to produce. each ball sells for $8.32. write the equations for the total cost, c, and the revenue, r, then use the graphing method to determine how many balls must be sold to break even.

Another type of subtraction equation is 16-b=7. explain how you would sole this equation then solve it.
