Well, I saw my teacher solving the test herself, and then grading papers off of her paper that she solved. My teacher made the answer key for the tests.
Answer:10
Step-by-step explanation:
if a song costs $1.50 and a video is 2 times that amount of a song, then the video would cost $3. you have a balance of $60. you by 15 videos to start. i multiplied $3 by 15 to get the cost of the movies, witch is $45. after i got the cost of the movies i subtracted the $45 from the over all amount, i got 15. now to the songs. i have $15 to get music. 2 songs costs $3( 1.50+1.50= 3.00). 4 songs would cost $6. 8 songs would cost $12. after that i just added 1.50 until i hit a total of 15. so you can get 10 songs for $15
There are 3 toppings, the probability of picking pepperoni is 1/3.
There are 2 sizes, the probability of choosing a large would be 1/2.
The probability of picking both would be 1/3 x 1/2 = 1/6
The answer would be D. 1/6

Step-by-step explanation:
<em>The question is incomplete as the input and output values are not given. However, the question can still be solved by assuming both values</em>
Given
In this case;
x represents the input while g(x) represents the output
Now, assume x = 2; Determine the output.
Here we simply substitute 2 for x in the above expression
i.e.
becomes
Similarly, if x = 5
Also, let's assume g(x) = -21; Determine the input
becomes
Solve for x
To solve this, you need to isolate/get the variable "c" by itself in the equation:
4c + 8c = -55 + 3c You can first combine like terms (4c and 8c)
12c = -55 + 3c Subtract 3c on both sides
9c = -55 Divide 9 on both sides
