The first question i have is what is 19 divide by 1/10. the second question is what is 2/9 multiply by 18. the third question i have is if lamont's buys 9gallons of ice cream for his party, he has 34 guest coming, if each guests eats 2 1/2 cups of ice cream , how many pints of ice cream will be left over? the 4 question i have is if india can paint 3 1/5 walls in one day, how many walls can she paint in 5 1/2. the 5 question i have is if hector can gather 10 2/5 pounds of crops in one day. how many pounds of crops can hector gather in 3 1/4. the last question i have is if miguel delivered 7 containers of orange juices to the apple tree resturant. each container had 8 quarts of orange juices. how many gallons of orange juices did miguel delivery.

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 ☺
