Last saturday nakesha rented 4 movies from the video store. this saturday she rented 2 movies. let x represent the cost of renting each movie. write and simplify and expression for how much more nakesha spent last week renting movies

8

Step-by-step explanation:

you have to do 4 times 2 which you have to add 4 two times which equals 8

( x  equals 8

- "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."
