26=5-7k i just need to remember how to do these types of problems, please tell me how to work these out

-3=k

Step-by-step explanation:

First you have to remove the numbers that are in the side of the variable,by changing them with the opposite from both sides

26-5=5-7k-5

21=-7k

now you have to divide both sides by the number the variable is next to

21/-7=-7k/-7

-3=k

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.

there is no grid
