Answer:
Step-by-step explanation:
Consecutive interior angles between parallel lines are supplementary.
Let's start with x.
(8x +40)° +(6x)° = 180°
14x +40 = 180 . . . . . . . . . divide by °, collect terms
14x = 140 . . . . . . . . . subtract 40
x = 10 . . . . . . . . divide by 14
__
We can use the same approach for y:
(7y)° +(3y -10)° = 180°
10y = 190 . . . . . . . . . . . divide by °, add 10, collect terms
y = 19 . . . . . . . . . . . divide by 10
Answer:
(a+b)² - 2ab
Step-by-step explanation:
it is a formula :)
Step-by-step explanation:
since there is no other information, we have to assume that the prices for student passes and teacher passes are the same.
therefore, the pass price per person is
$737.38 / (44 + 2) = $737.38 / 46 = $16.03
and the lunch costs per student are
$393.36 / 44 = $8.94
altogether,
$16.03 + $8.94 = $24.97
was spent for each student.
