Answer:
$2.50
Step-by-step explanation:
The question asks for the total cost of a notebook and pen together. We don't need to find their individual costs in order to answer the question.
Sometimes we get bored solving systems of equations in the usual ways. For this question, let's try this.
The first equation has one more notebook than pens. The second equation has 4 more notebooks than pens. If we subtract 4 times the first equation from the second, we should have equal numbers of notebooks and pens.
(8n +4p) -4(3n +2p) = (16.00) -4(6.50)
-4n -4p = -10.00 . . . . . . . . . . . simplify
n + p = -10.00/-4 = 2.50 . . . . divide by the coefficient of (n+p)
The total cost for one notebook and one pen is $2.50.
__
Additional comment
The first equation has 1 more notebook than 2 (n+p) combinations, telling us that a notebook costs $6.50 -2(2.50) = $1.50. Then the pen is $2.50 -1.50 = $1.00.
One could solve for the costs of a notebook (n) and a pen (p) individually, then add them together to answer the question. We judge that to be more work.

What is x and y??
9514 1404 393
Answer:
x = 90y = 64Step-by-step explanation:
If we take the arcs to mean that those angles are congruent, then the sum of exterior angles is ...
x° +2y° +75° +67° = 360°
y = 109 -x/2 . . . . . . subtract non-x terms and divide by 2
Because x° forms a linear pair with a right angle, we know ...
x° = 180° -90° = 90°
Then ...
y = 109 -90/2 = 64
The values of x and y are 90 and 64, respectively.

Which ones are functions and which ones are not
Answer:
For the graph part, A is not a function and B is a function. For the bottom part, A is a function and B is not a function.
Step-by-step explanation:
Top
A is NOT a function because it had failed the vertical line test, meaning that it has multiple outputs for each input which makes it not successful when taking the vertical line test. B is a function since it passed the vertical line test. Always use the vertical line test to see whether or not the graph met the requirement of having the input have one output.
Bottom
A is a function because the input contains one output. B is NOT a function since 5 contains 2 different outputs.
The outputs can be with multiple inputs, whereas the inputs cannot be with multiple outputs since they wouldn't meet the requirement during the vertical line test.
The Bremen City School System is opening an all girls academy next school year. The girls choose one top (Green or Yellow), one pant (Khaki or Blue, and one pair of shoes (dress or white), What is the probability of choosing white shoes and a green shirt?
Answer:
0.25 = 25% probability of choosing white shoes and a green shirt
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question:
The probability of choosing a shoe is independent of the shirt. So we find each separate probability, and then multiply them.
Probability of choosing white shoes:
2 shoes option, one of which is white. So
[tex]P(A) = \frac{1}{2}[/tex]
Probability of choosing a green shirt:
2 shirts options, one of which is green. So
[tex]P(B) = \frac{1}{2}[/tex]
What is the probability of choosing white shoes and a green shirt?
[tex]P(A \cap B) = P(A)*P(B) = \frac{1}{2} \times \frac{1}{2} = \frac{1}{4}[/tex]
0.25 = 25% probability of choosing white shoes and a green shirt

carline drives 25 minutes to the store. it takes her 3 minutes to walk in the store from the parking lot. If carline spends 5 hours and 36 minutes traveling to the store and back in one month, how many round trip visits to the store does carline take to the store each month
Answer:
6 round trip visits
Step-by-step explanation:
25 min drive to the store + 3 min to walk in the store + 3 min to walk back to car + 25 min to drive home = 56 total minutes for one round trip.
5 hours and 36 minutes = (5x60)+36 minutes=336 minutes
336 minutes/56 min per trip = 6 round trips
