Mara's family is driving to her grandmothers' house. The family travels 239.4 miles be- tween the hours of 9:10 a. m. to 1:40 p. m. Write an equation that Mara can use to deter-
mine their average rate of travel, rounded to the nearest mile per hour.
Use the given numbers and operations to complete an equation.

Triangle xyz, with vertices x(-2, 0), y(-2, -1), and z(-5, -2), undergoes a transformation to form triangle x? y? z? , with vertices x? (4, -2), y? (4, -3), and z? (1, -4). the type of transformation that triangle xyz undergoes is a . triangle x? y? z? then undergoes a transformation to form triangle x? y? z? , with vertices x? (4, 2), y? (4, 3), and z? (1, 4). the type of transformation that triangle x? y? z? undergoes is a .
