X + Y = 24
5x + 3y = 100
Now take the first equation and solve for one variable. We will start with X
X = 24 - Y
Now we have a value for x (24-y). Plug this value for x into the second equation
5(24-y) + 3y = 100
Now solve for y
120 - 5y + 3y = 100
120 -2y = 100
-2y = -20
Y= 10
Now we have the exact y value. Plug this value into the second equation to solve for x
5x + 3(10) = 100
5x + 30 = 100
5x = 70
X = 14
Now check your work by plugging both the value for x and y into the first equation
14 + 10 = 24
24 = 24
X = 14
Y = 10

Which of the following is a polynomial?
Answers
Answer:
C
Step-by-step explanation:
Polynomials should consist of only non-negative integer powers of x. Thus B and D are definitely not. It might be possible to simplify A into something that looks like a polynomial, but it’s a bit difficult. If you just need to choose one, then C is definitely a good choice.

A 2-column table with 9 rows. The first column is labeled year with entries 1970, 1975, 1980, 1985, 1990, 1995, 2000, 2005, 2010. The second column is labeled pounds of trash with entries 3.25, 3.25, 3.66, 3.83, 4.57, 4.52, 4.74, 4.69, 4.44.
The table shows the average number of pounds of trash generated per person per day in the United States from 1970 to 2010. Use the statistics calculator to calculate the mean and median. Round the answers to the nearest hundredth.
Answers
Answer:
The median of a list of numbers is the center number when you order the numbers from least to greatest.
Since there are 9 numbers; the center number is the fifth number. Four numbers below and four numbers above. Median is 4.44 and the mean or average is 4.09.
Step-by-step explanation:
List in order from least to greatest
(3.25, 3.25, 3.66, 3.83) 4.44 ( 4.52, 4.57, 4.69, 4.74) Notice 4 numbers below 4.44 are lower and 4 numbers above 4.44 are higher. So the median number is 4.44
For the mean you add all the number and divide the sum by the number of numbers you have. We know you have 9 numbers from the first part. So, add the numbers from the list (3.25 +3.25+ 3.66 + 3.83 + 4.44 + 4.52 + 4.47 + 4.69 + 4.74) = 36.85 Then divide by 9 = 4.09
Anna has a recipe for pumpkin bars. She uses 2 ½ cups of sugar for every 3 pans of pumpkin bars. AJ wants to follow the same recipe. He will make h pans of pumpkin bars using g cups of sugar. Which of these equations best represents the relationship between h and g?
Answers
Answer:
[tex]2.5h = 3g[/tex]
Step-by-step explanation:
Given
[tex]Sugar = 2\frac{1}{2}\ cups[/tex]
[tex]Bars = 3\ pans[/tex]
Required
Determine the equation for h pans and g cups
We have that:
[tex]Sugar = g[/tex]
[tex]Bars = h[/tex]
To do this, we make use of the following equivalent ratios.
[tex]Bars : Sugar = Bars : Sugar[/tex]
So, we have:
[tex]3 : 2\frac{1}{2} = h : g[/tex]
Express fraction as decimal
[tex]3 : 2.5 = h : g[/tex]
Express as fraction
[tex]\frac{3}{2.5} = \frac{h}{g}[/tex]
Cross multiply
[tex]2.5h = 3g[/tex]

169 = hypotenuse squared.
hypotenuse = sqrt(169)

98 is 0.7% of what number? Use pencil and paper. Would you expect the answer to be a lot less than 98, slightly less than 98, slightly greater than 98, or a lot greater than 98? Explain.
Answers
Answer:
x = 14000
Step-by-step explanation:
98 is 0.7% of x number.
According to the question,
[tex]0.7\%\ of\ x=98\\\\x=\dfrac{98}{0.7\%}\\\\x=\dfrac{98}{\dfrac{0.7}{100}}\\\\=\dfrac{98\times 100}{0.7}\\\\=14000[/tex]
So, 0.7% of 14000 is equal to 98. Hence, this is the required solution.
The two objects are the same height, and the cylinder is just wide enough for the the box to fit inside with all 4 vertical edges of the box touching the inside of the cylinder. if the box of pasta fits 8 cups of rice, estimate how many cups of rice will fit inside the cylinder. Expalin or show your reasoing
Answers
Answer:
The answer is below
Step-by-step explanation:
The volume of a box with a length of l, width of w and a height of h is given by the formula:
volume of the box = length * width * height = lwh
The volume of a cylinder with a height of h, and radius r is given by the formula:
volume of the cylinder = π * radius² * height = πr²h
Since the box and the cylinder have the same height and the cylinder is wide enough for the box to be placed inside, this means that the box has a volume greater than that of the cylinder. Hence:
If the box can take 8 cups, the cylinder would be able to take 10 cups.

Answer:
x = 15
Step-by-step explanation:
Simplifying
3x + (8x + 15) = 180
Reorder the terms:
3x + (15 + 8x) = 180
Remove parenthesis around (15 + 8x)
3x + 15 + 8x = 180
Reorder the terms:
15 + 3x + 8x = 180
Combine like terms: 3x + 8x = 11x
15 + 11x = 180
Solving
15 + 11x = 180
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-15' to each side of the equation.
15 + -15 + 11x = 180 + -15
Combine like terms: 15 + -15 = 0
0 + 11x = 180 + -15
11x = 180 + -15
Combine like terms: 180 + -15 = 165
11x = 165
Divide each side by '11'.
x = 15
Simplifying
x = 15

x=15 Hope this helps :)

Answer:
15.27 ≅ 15 pounds if I'm not wrong :(
Step-by-step explanation:
11 projects : 24 pounds
