Answer:
Michelle = 25
Alyssa = 13
Amanda = 9
Step-by-step explanation:
We will set up equations for this problem to help us solve this problem mathematically. Let x be Alyssa, y be Michelle, and z be Amanda.
[] Alyssa is 12 years younger than Michelle.
x = y - 12
[] Michelle 25 ()is 7 years older than twice Amanda's age.
y = (2x) + 7
[] The sum of all three ages is 47.
x + y + z = 47
You gave that y = 25,
Michelle is 25.
Since we know that Alyssa is 12 years younger than Michelle, we can solve for Alyssa.
x = 25 - 12
x = 13
Alyssa is 13.
Lastly, the sum of all three ages is 47.
x + y + z = 47
13 + 25 + z = 47
z = 9
Amanda is 9.

Answer:
C
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
The answer is B because you need to divide 851 with 46, and the answer is 18.5. You then convert that to a mixed fraction into simplest form. You can do this by placing the decimal number over it's place value.
Find the surface area of the right rectangular prism shown below.
units^2
Step-by-step explanation:
Formula = A=2(wl+hl+hw)
L = 4W = 2H = 2.5=> A=2(wl+hl+hw)
=> A = 2((2)(4)+(2.5)(4) + (2.5)(2))
=> A = 2(8 + 10 + 5)
=> A = 2(23)
=> A = 46
[tex] \therefore [/tex] Surface area = 46

)A polygon is shown:
A polygon MNOPQR is shown. The top vertex on the left is labeled M, and rest of the vertices are labeled clockwise starting from the top left vertex labeled M. The side MN is parallel to side QR. The side MR is parallel to side PQ. The side MN is labeled as 4 units. The side QR is labeled as 7 units. The side MR is labeled as 3 units, and the side NO is labeled as 2 units.
The area of polygon MNOPQR = Area of a rectangle that is 12 square units + Area of a rectangle that is ___ square units. (Input whole numbers only, such as 8.)
Answer:
3
Step-by-step explanation:
They are cutting the whole shape up into two rectangles. Draw the extension of NO all the way down to QR see image. The whole shape's Area is the sum of the areas of the two rectangles. The bigger rectangle on the left has area 3×4, area =12. The smaller rectangle on the right has area 3×1, area = 3.
This is the fill in the blank they are asking for. You have to subtract 3-2 for the length of one side. And 7-4 for the length of the other side.. Area = 3×1 =3 see image.
(If there is a followup question asking for the total area of MNOPQR it is 12+3 =15)

Solve the system of equations by graphing.
Answer:
x = -2, y = -4 (-2,-4)
Step-by-step explanation:
1. Substitute "y = 2x+ in for y in "x + y = -6"
x + 2x = -6
2. Combine like terms:
3x = -6
3. Isolate x:
3x/3 = -6/3
x = -2
4. Substitute the new x-value in one of the equations:
y = 2(-2)
y = -4
The graph should look like the picture attached.

"A shipping container will be used to transport several 100-kilogram crates across the country by rail. The greatest weight that can be loaded into the container is 24500 kilograms. Other shipments weighing 9100 kilograms have already been loaded into the container. Use the drop-down menu below to write an inequality representing cc, the total number of 100-kilogram crates that can be loaded into the shipping container."
[tex]\qquad\qquad\huge\underline{{\sf Answer}}[/tex]
Let the number of 100 - kilogram crates be x
According to question, The load capacity of container is 24500 kgs, and other shipments already weight 9100 kgs, now we have to find out how many 100 - kg crates can be loaded into the shipping container.
[tex]\qquad \tt \dashrightarrow \:100x + 9100 \leqslant 24500[/tex]
[tex]\qquad \tt \dashrightarrow \:100x \leqslant 24500 - 9100[/tex]
[tex]\qquad \tt \dashrightarrow \:100x \leqslant 15400[/tex]
[tex]\qquad \tt \dashrightarrow \:x \leqslant 154[/tex]
So, the maximum number of 100 - kg crates that can be loaded on the container is 154

Answer:
larger circle is 75.4
smaller circle is 50.27
Step-by-step explanation:
Answer:
Larger circle= 75.4
Smaller circle= 50.27
Step-by-step explanation:
Use this formula: C=2πr
Find the radius for bigger and smaller circle
The radis of the smaller is equal to: 12 - 4 =8
radius of smaller circle= 8
radius of bigger circle = 12
make an equation for one of the circles: (i chose the smaller one)
C=2π(8)
C= 16 π
C= 50.27
Now for the bigger circle
C=2π(12)
C=24π
C= 75.39
C= 75.4

Julian forgot his bat when he left for baseball camp. His mother finds a box to ship it to him with the dimensions shown. If the bat measures 34 inches long, will the bat fit inside the box? Drag words to complete the statements about the diagonal of the base and the interior diagonal of the box. Words may be used once, more than once, or not at all.
Answer:
It WILL NOT fit inside the box as the length is LONGER THAN the box.
However, diagonally, it can as by The Pythagoras Theorem, a^2+b^2=c^2.
Diagonally, it is 32.984 inches (5s.f)
Step-by-step explanation:
The box is 32 inches while the bat is 32 inches

Answer:
"What is your favorite vegetable?" for the first one and Choices A and B are correct for the second one.
Step-by-step explanation:
For the first image/question:
The first survey question is correct and gives you the most data.
"What is your favorite vegetable?"
That question gives a variety of choices and also gives you data similar
to each other.
Ex. 12 people like potatoes, 15 people like corn. 5 people like spinach, etc.
This amount of data is easier to present/graph and also very common/open-ended as opposed to questions like "In which zipcode do you live in?"
Second Question:
The data set can represent the weight of a dozen eggs and could possibly represent the length of leaves from a tree if measured in Centimeters.
A and B are the right choices.
The other few options aren't appropriate due to the data.
