Answer:
x = 10
Step-by-step explanation:
The sum of the interior angles of a quadrilateral = 360°
Sum the angles and equate to 360
9x + 15 + 85 + 90 + 80 = 360, that is
9x + 270 = 360 ( subtract 270 from both sides )
9x = 90 ( divide both sides by 9 )
x = 10

Answer:
1st option
Step-by-step explanation:
the constant of proportionality is the cost divided by number of patrons
$49.96 ÷ 4 = $12.49
$74.94 ÷ 6 = $12.49
$87.43 ÷ 7 = $12.49
Thus each movie ticket costs $12.49
x + (-4) = 10.
We can use the positive - negative rule.
x + (-4) = 10.
x - 4 = 10.
x = 10 + 4
x = 14.
