The Northwest High School senior class decided to host a raffle to raise money for their senior trip. They charged $2 for each s

prisoha [69]

Let $x$ be the tickets that the adults bought, and $y$ be the tickets that children bought.
From the problem we have the system of linear equations:
$\left \{ {{2x+5y=2686} \atop {y=3x}} \right.$

The first thing we are going to do to solve our system, is replacing equation (2) in equation (1), and then, solve for $x$
$2x+5y=2686$
$2x+5(3x)=2686$
$2x+15x=2686$
$17x=2686$
$x= \frac{2686}{17}$
$x=158$

Now that we have the number of tickets that the adults bought, lets replace that value in equation (2):
$y=3x$
$y=3(158)$
$y=474$

Last but not least, to find the total number of tickets, we are going to add $x$ and $y$ :
$158+474=632$

We can conclude that <span>Northwest High School's senior class sold 632 raffle tickets.</span>

Please help me !!!

Answer:

x = 47

2x+6 = 100 which is the angle measure

Step-by-step explanation:

The angles are vertical and vertical angles are equal

2x+6 = 100

Subtract 6 from each side

2x+6-6 =100-6

2x = 94

Divide by 2

2x/2 = 94/2

x =47

Now to find the measure of 2x+6

We know that it is equal to 100

so 2x+6 = 100

In a group of 60 students, 14 students take Algebra I, 20 students take

Ratling [72]

Answer:19 students

Step-by-step explanation:

First you would add together all the students that you know take a math class. So you would add 14+20+7 to get 41 students. So now you know that that many students take a math class. So you would do 60-41 because 60 is your overall number of students. After you subtract them you should get 19 which is your answer-19 students don’t take either of the subjects

Classify each function as even, odd, or neither even nor odd.

drek231 [11]

The function

f(x) is even

g(x) is neither even nor odd

h(x) is odd

Steps:

for an even function it holds that f(-x) = f(x):

f(-x) = (-1)^6 x^6 - (-1)^4 x^ 4 = x^6 - x^4 = f(x) => f is even

for an odd h(x) it holds that h(-x) = -h(x):

$h(-x) = (-1)^5x^5-(-1)^3x^3 = -(x^5-x^3) = -h(x) \implies h(x)\,\, \mbox{even}$

It is easy to show that g(x) does not match any of the two possibilities above.
