5t+13=6t+10 and explain how you got your answer. i have trouble with equations like this and would like to understand.

Note the equal sign. What you do to one side, you do to the other. Isolate the variable, t. Remember to do the opposite of PEMDAS.

t = 3 is your answer

Hope this helps

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.
