Solve: the quantity 2x minus 20 divided by 3 = 2x
x = −5
x = −2
x = 2
x = 13

x = -5

Step-by-step explanation:

(2x-20) / 3 =2x

2x - 20 =6x

4x = -20

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.
