Error Analysis The solution shown for the equation is
incorrect. What is the correct solution? What is the error?
-5(3-1) = 30
- 15-5r = 30
51 = 45
r =
-9
The solution is 9. (Type the value of r.)
What is the error?
O A. The right side of the equation should be 15 after subtracting – 15 from each side.
O B. The right side of the equation should be 9 after dividing each side by - 5.
O C . The left side of the equation should be -r after dividing each side by -5.
OD. The left side of the equation should be - 15+5r after distributing.

answer: '

the distance between points l and m

step-by-step explanation:

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 ☺

answer: 270

step-by-step explanation:

you have to times 200 by 1.35 to get your answer
