9x-3+10-5x=9x-5x-3+10 the question is: list which of the associative and commutative properties are being used

The given equation is:

9x-3+10-5x = 9x-5x-3+10

1. Associative property of addition: when three or more numbers are added the sum is same regardless of the grouping of the numbers.

(9x -5x) + (10-3) = (9x -5x) + (10-3)

2. Commutative property of addition: This property states that the numbers can be added in any order without changing the resulting answer/ sum.

9x-3+10-5x= -3+10+9x-5x

its d but looking at that hurts my eyes frfr

step-by-step explanation:

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.
