Which property is illustrated by the statement? 8 + 3.4 = 3.4 + 8
Associative Property of Addition
Inverse Property of Multiplication
Commutative Property of Addition
Inverse Property of Addition

Step-by-step explanation:

The Commutative Property of Addition changes the order of the numbers but does not affect the sum.

Example :-

answer: the answer is 35%

- "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."
