Two freight trucks are traveling to the same destination, and each are traveling at a constant speed. Truck A is 187 miles away from its destination at 9 a. m., one hour after leaving from its origin, and is 99 miles away from the destination at 10:36 a. m. Truck B started
traveling to its destination at 6:30 a. m. Truck B is 248 miles away at 8:30 a. m. and 155 miles away at 10 a. m. Analyze each situation
to determine a function that finds the distance to the destination for each truck based on the time in hours after starting the trip from
the origin to the destination. Then use the functions to determine which truck will arrive first to its destination.

Step-by-step explanation:

Uhm, try multiplying the destinations of chuck a B and see what they both start a diet and then where they ended at the end if that makes sense

step-by-step explanation: so we look at the formula un = a + (n-1)d

un is the amount of seats

n is the nth term aka row number

a is the original sequence/row number

d is the difference between each term

so in this a=22 d=6 and n can remain as n because we are simply formjng a rule

lets put these in the equation

un=22+(n-1)(6)

this is your answer to part a

however

lets double check that this is correct, we'll try putting it into the second term

un=a+(n-1)d

u2=22+(2-1)(6)

u2=22+6

u2=28

as the question said the second row has 28 seats so now we know the formula we made is correct.

as for part b

un=a+(n-1)

its asking us to find a row with 100 seats.

remember un was the amount of seata so all we do is substitute this in.

un=100 a=22 d=6

un=a+(n-1)d

100=22+(n-1)(6)

so now we simplify to find n which is the row number.

100-22=22+(n-1)(6)-22

78=(n-1)(6)

78/6=(n-1)(6)/6

13=n-1

13+1=n-1+1

14=n

so now we know that in the 14th row there is 100 seats.

hope this and that you understood! its my first time using the app or anyone out on here : p its also me to revise so a bunch! ask more questions if you dont understand ☺
