Answer:
An adults ticket costs $9
Step-by-step explanation:
Kids:
$7
Adults:
$9
So if you add 7+7+7= 21 (kids)
then do 9+9=18(adults)
Then add them together you get 39$
Answer:
3x+6y-2z+14
Step-by-step explanation:
Lets find all the numbers..
x (1st number)
x + 2 ( 2nd number)
x + 4 (3rd number)
x + 6 (4th number)
x + 8 (5th number)
x + 10 (6th number)
Now add all those expressions and set them equal to 270 because that is the total.
x + x + 2 + x + 4 + x + 6 + x + 8 + x + 10 = 270
6x + 30 = 270
6x = 240
x = 40
Now we will substitute 40 for x in the expression of the second number.
x + 2
40 + 2
42
So the second number is 42
Hope this helps :)
Answer:
The answer to your question is below
Step-by-step explanation:
(5x³ + 3x² - 7x + 10) - (3x³ - x² + 4x - 1)
5x³ + 3x² - 7x + 10 - 3x³ + x² - 4x + 1
(5x³ - 3x³) + (3x² + x²) + (-7x - 4x) + (10 + 1)
2x³ + 4x² - 11x + 11
It is a polynomial because it has 4 terms
It is of third degree because the highest degree is 3.
