Dale’s mom is throwing him a birthday party. she plans to serve three slices of pizza to each of the 12 kids that are attending. she can get a slices per box from the pizzeria. write the number of boxes she will use as a mixed number.

you need to know the number of slices in a box then then do 12 times three and how many boxes peices that are close to 12 times three is the answer

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
