You need to spend exactly $20 to buy eggs at $1 per carton of a dozen eggs and cheese at $2 per block containing eight ounces of cheese to make omelettes There must be exactly twice as many eggs as ounces of cheese in the
omelettes. How many cartons of eggs and blocks of cheese should you buy?
Next think about what equation represents the fact that there must be twice as many eggs as ounces of cheese in
the omelette. Let
x=the number of cartons of eggs (with 12 eggs in each carton) and
y=the number of blocks of cheese (with 8 ounces of cheese in each block).

sorry can't

step-by-step explanation:

i googled though and something came up but it was in science langueage not common english sooo

c. side angle side. u shares the same sides

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol

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 ☺
