You ride your bike at 9 miles per hour. to find how long it will take you to ride 26 miles, you solve the equation 9 • t = 26. what does t represent?

the amount of time it takes to ride 26 miles

your speed in miles per hour

the number of miles you've traveled so far

the total distance after t hours

The amount of time it takes to ride 26 miles is 2.89 hours.

Step-by-step explanation:

Given : You ride your bike at 9 miles per hour.

To find : How long it will take you to ride 26 miles ?

Solution :

The equation given is

Using distance formula,

According to formula t represent the time taken to cover the distance.

Your speed in miles per hour is 9 miles per hour.

The number of miles you've traveled so far is 26 miles.

Solving the equation,

hours

The amount of time it takes to ride 26 miles is 2.89 hours.

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 ☺
