Eddie and janice are buy school supplies. eddie buy’s 5 notebooks and 5 binders for a total of $25.45. janice buy’s 4 notebooks and 8 binders for $30.00. what is the coast of each item?

the answer is simply just 6n add the two together as they have an n

- "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."

33/100 is what i got
