8times the difference between a number and 6 is equal to 4 times the number.

what is the number

 12

Step-by-step explanation:

Let the number be x.

Given statement: 8 times the difference between a number and 6 is equal to 4 times the number.

then, the required equation :

Divide both sides by 4 , we gte

Simplify

Multiply 2 inside the parenthesis.

Subtract x and add 12 on both sides , we gte

Simplify

Hence, the number is 12.

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.
