Explain how to model the division of –20 by –5 on a number line.

For what value of x does 4x = (1/8) x + 5?

Suppose that the price p, in dollars, and the number of sales, x, of a certain item follow the equation 4 p plus 4 x plus 2 pxequals56. suppose also that p and x are both functions of time, measured in days. find the rate at which x is changing when xequals2, pequals6, and startfraction dp over dt endfraction equals1.5.

Simplify using positive exponents only.
