Mavis and Travis discuss strategies for estimating and comparing 61,000 and 29,000. Mavis says she rounds each number to its greatest place and writes it as a single digit times a power of 10, before comparing them. Travis says he can get the same answer just by rounding each number to the nearest power of 10, and then comparing them. Is Travis correct?

Equations and Inequations

Equations and inequalities describe the relationship between two mathematical expressions.

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
