Adult tickets to the fall play cost $8
iren2701 [21]

Solving a system of equations we will see that they sold 80 adult tickets.

<h3>how many adult tickets were sold?</h3>

To solve this, we need to solve a system of equations. To define said systems of equations, we first need to define the variables, we will use:

  • x = adult tickets sold.
  • y = student tickets sold.

They sold 20 more adult tickets than student tickets, then:

x = y + 20

And they collected a total of $880, then:

x*$8 + y*$4 = $880

The the system of equations is:

x = y + 20

x*$8 + y*$4 = $880

Isolating y on the first equation we get:

y = x - 20

Replacing that on the other equation we get:

x*$8 + (x - 20)*$4 = $880

Now let's solve that for x.

x*$12 - $80 = $880

x*$12 = $880 + $80 = $960

x = $960/$12 = 80

They sold 80 adult tickets.

PLEASE HELP For what value of the variable will the value of 2x+1 be 20 greater than 8x+5?
wlad13 [49]

It will be a negative.

for an example: -20 for x would mqke 2x + 1 into -39 and 8x + 5 into -155. that's 116 apart, so maybe -2(8) + 5 = -11

-2(2) + 1 = -3

but that's only 8 apart, so it'd be higher.

-4(2) + 1 = -7

-4(8) + 5 = -27

BOOM

Tadaaaa,

You probably thought positive, but sometimes it's negative, you know what I mean?
