Jillana begins to solve a linear equation that results in a variable expression set equal to the same variable expression. which is the best interpretation of this solution? a. the equation has one solution: x = 0. b. the equation has one solution: x = 1. c. the equation has no solution. d. the equation has infinite solutions.

The best interpretation of this solution is:

             D. The equation has infinite solutions.

Step-by-step explanation:

It is given that:

Jillana begins to solve a linear equation that results in a variable expression set equal to the same variable expression.

So, such a equation have infinite solution.

Because for infinite values of the variable the equation will hold true as the value of the expression on the left as well as right hand side of the equality sign will be same and hence the equation is a valid equation with infinite number of solution.

Hence, the correct option is:

Option: D

D. The equation has infinite solutions.

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 ☺

the correct answer would be:

220 centimeters

to get this you can use the pythagorean theorem

hope this
