The school theater department made $2,142 on ticket sales for the three nights of their play. The department sold the same numbe
anyanavicka [17]

Answer:

102 tickets

Step-by-step explanation:

Let's say the total number of tickets sold is n.

7n = 2142

 n = 2142 ÷ 7

 n = 306

They sold 306 tickets in total.

We want to know how much they sold per night. We know they sold the same number of tickets each night for three nights.

306 ÷ 3 = 102

Therefore, they sold 102 tickets each night.

I hope this helps :)

PLEASE HELP!!This is joshs solution for the equation x^2-6x-7=0: x^2-6x-7=0
iren [92.7K]

Answer:

  no. see below

Step-by-step explanation:

This much of Josh's working is correct:

  x^2-6x=7

  x^2-6x+9=7+9

  (x-3)^2=16

At this point Josh apparently overlooked the fact that he needed to take the square root of both sides of the equation. Had he done that, he would have ...

  x -3 = ±4

  x = 3+4 . . . or . . . 3 -4

  x = 7 or -1

_____

Josh reported values of x that would match ...

  x -3 = ±16

He <em>violated the equal sign</em> by taking the square root on the left, and multiplying by ±1 on the right. Doing different operations on the two sides of the equation will mean the value of x is changed to something other than what you're looking for.
