Please Help Me! I would be really grateful!

weight in an elevator must be less then 2000 - w is less then 2000 or the first option

a ton is 2000 lbs - w=2000

the pool must hold at least 2000 gallons - the second option

the scale can hold up to and including 2000 lbs - the fourth option

my car weighs more then 2000 lbs- the last one

I think this is right, I hoped I helped

2nd one in the first row is correct

- "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."
