21. BRAINLIEST! URGENT!

100

Step-by-step explanation:

here we are solving for x

first plug in 100 for the ys in the equation

0.10x + 0.10(100) = 0.18(x + 100)

simplify

0.10x + 10 = 0.18x + 18

get x by itself

-8 = 0.08x

-100 = x

so the reasonable answer here would be 100

hope this helps <3

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.

the answer is. -82562234434584
