Solve using process of elimination: 5x+4y=14. -2x-8t=20

Bet

Step-by-step explanation:

First One:

5x + 4y = 14

5x = 14 - 4y

x =  14/5 - 4y/5

Second one:

-2x - 8t = 20

-2x = 20 + 8t

x = -10 - 4t

Another answer would be:

x = −6, y = 4

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.
