Laraba has x naira. kunle has 15 naira less than laraba. together, the number of naira they have is: A x- 15
B 2x
C 2x-15
D 2x+15
E 15​

9514 1404 393

  C.  2x -15

Step-by-step explanation:

The respective numbers of naira are ...

  laraba: x

  kunie: x-15 . . . . . 15 less than laraba

Then the total is ...

  laraba + kunie = x +(x -15) = 2x -15 . . . . matches choice C

- "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."

x coordinate is none
