Can someone me with this? problem here: write an expression for the sequence of operations described below. double 10, then add g to the result do no simplify any part of the expression.

Hi There!

Solution:

Double 10 = 10 * 2 = 20

Add g to the result above = 20 + g

20 + g

Hope This Helps :)

over the argument its not good to fight.

- "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."
