Two caseworkers share an office. The first caseworker has fifteen active cases. The second caseworker has twice the number of active cases. How many cases does the office have. solve and write an equation.

45

Step-by-step explanation:

f= # of cases the first caseworker has

t= total number of cases

equation: t = 15+2f

Simple the answer is 45

1 caseworker has 15 cases and th ther has twice as many so thats multiplication, which is 15x2=30. then they asked how many cases does the office have so thats both the workers combined which is 15+30=45

so 15x2=30

15+30=45

- "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."
