Bryan reads for x minutes. kelly reads for one-fourth the amount of time bryan reads. which statement explains why 14x and 0.25x can each find the number of minutes kelly reads?
a multiplying by 14 is the same as multiplying by 25%.
b the fraction 14 is equivalent to the decimal 0.75, therefore, 14x can be rewritten as 0.75x.
c multiplying by 4 is the same as multiplying by 25%.
d the expressions are not equivalent

the correct answer would be c i took the test and i know its correct

have a nice day

d. 8

step-by-step explanation:

the given radical expression is:

we can rewrite this as:

we express as square numbers to get;

the exponents will now cancel out to give.

the correct answer is d

- "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."
