Andre is running in an 80-meter hurdle race. There are 8 equally-spaced hurdles
on the race track. The first hurdle is 12 meters from the start line and the last
hurdle is 15.5 meters from the finish line. Estimate how far the hurdles are from
one another.

Nick has box brads. he uses 4 brads for the first project. nick let’s b represent the original number of brads and finds that for the second project, the number of brads he uses is 8 more than half the difference of b and 4. write an expression to represent the number of brads he uses for the second project.

Lena reflected this figure across the x-axis. she writes the vertices of the image as a'(−2, 8), b'(−5, 6), c'(−8, 8), d'(−4, 2).

The table shows the age and finish time of ten runners in a half marathon. identify the outlier in this data set. drag into the table the ordered pair of the outlier and a reason why that point is an outlier.
