Six times the sum of three consecutive odd integers is -18. what are the integers?

-3, -1 and 1.

Step-by-step explanation:

If we define a number as , the next odd number is , and the next is , so three consecutive odd integers are: , and .

the sum of these consecutive numbers is:

and six times that sum:

which is equal to:

and the problem statement indicates that 6 times the sum of the three consecutive odd integers is equal to , so:

clearing for x:

so if , and

the three integers are: -3, -1 and 1.

answer: it's d

step-by-step explanation:

- "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."
