Answer:
1). 9 red 6 fancy 2). 50 shirts 20 pants 3). 62 purple 31 red 4). 19 dimes 9 quarters
Step-by-step explanation:
Most are systems of equations. So, they will have more than one equation.
1). x (Red wrapping paper) y (fancy print paper)
x + y = 15
2x + 4y = 42
Solved: x = 9 y = 6
2). x (shirts) y (pants)
x + y = 70
12x + 30y = 1200
Solved: x = 50 y = 20
3). x (purple) y (red)
I ended up dividing 93 by 3 and then multiplying it by 2 for purple and keeping the other third for red. Not quite sure how to fit this into an equation, its just simple math.
Solved: x = 62 y = 31
4). x (dimes) y (quarters)
.10x + .25y = 4.15
x = y - 10
Solved: x = 19 y = 9

326/6 is 54 1/3, which is 324 remainder 2
(A) Mean best describes the amount of water in each bucket.
<h3>
What is mean?</h3>
- A dataset's mean (also known as the arithmetic mean, as opposed to the geometric mean) is the sum of all values divided by the total number of values.
- It is the most widely used measure of central tendency and is frequently referred to as the "average."
- In mathematics, particularly statistics, there are several types of means.
- Each mean is used to summarize a specific set of data, often in order to better understand the overall value (magnitude and sign) of a given data set.
- In two simple steps, we can calculate the mean or average of a data set: add up all of the values to find the sum.
- Subtract the sum from the total number of values in the data set.
Therefore, (A) mean best describes the amount of water in each bucket.

Answer:
x = 9 and y = -3
Step-by-step explanation:
Let's say the first integer is x and the second one is y. Then, if we put the words into mathematical expressions, we get:
x = 15 + 2y
xy = -27
We can use substitution to solve this system of equations. We put 15 + 2y in for x in xy = -27:
(15 + 2y)*y = -27 ⇒ 2y² + 15y = -27 ⇒ 2y² + 15y + 27 = 0
Now, we have a quadratic to solve, so after some trial and error, we get:
(2y + 9)*(y + 3) = 0
Setting each of these to 0, we get two possible answers for y:
y = -9/2 or y = -3.
However, it says that y is an integer, so it can't be -9/2 and must be -3. We use this to find x:
x = 15 + 2*(-3) = 15 - 6 = 9
So, the two numbers are x = 9 and y = -3.
