150 feet

Step-by-step explanation:

Here is the complete question

Chloe is replacing three different sections of her of the fence in her backyard she needs fencing and length of 13 yards, 17-yards and 20 yards. How much fencing does she need in feet

Solution

To find the total number of fencing Chloe needs in feet, we first add up the amount she needs in yards and then convert it to feet. Since she needs fencing and length of 13 yards, 17-yards and 20 yards, the total length of fencing she needs in feet is L = 13yards + 17 yards + 20 yards = 50 yards.

We now convert 50 yards to feet, Since 1 yards = 3 feet, 50 yards = 50 × 1 yard = 50 × 3 feet = 150 feet.

So Chloe needs 150 feet of fencing.

step-by-step explanation:

if you meant, "on the way from (3, 2) to (3, 14):

x does not change; y increases by 12.

ensure that you have copied down this problem correctly.   .

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 ☺
