When solving the equation 5/18=5/4x+6 algebraically, it is possible to set the denominators of the fractions equal to each other. Is it possible to do this with other similar equations which consist of a fraction equal to a fraction, where the numerators are constants and one of the denominators contains a variable? A. No, not even if the numerators of both fractions are equal to 5.
B. No, not even if the numerators of both fractions are equal to each other.
C. Yes, but only if the numerators of both fractions are equal to 5.
D. Yes, but only if the numerators of both fractions are equal to each other.
Have evidence to your answer

1. 3. can also be expressed as (22/7)

2. -4.5

3. 3.6

happy to

pls mark as brainliest

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 ☺

6x = 48

i hope this . 6 cards each and a total of $48. dvide each side by 6 and you will have your answer.

sorry

step-by-step explanation:

sorry, but im pretty sure its a now that i look at it
