Answer:
let p = cost of 1 plain wrapping paper
let h = cost of 1 shiny rolls wrapping paper
Write an equation for each statement,
" Eugene sold 3 rolls of plain wrapping paper and 11 rolls of shiny wrapping paper for a total of $168 "
3p + 11h = $168
Jill sold 10 rolls of plain wrapping paper and 11 rolls of shiny wrapping paper for a total of $252."
10p + 11h = $252
Use elimination here,
10p + 11h = $252
3p + 11h = $168
subtraction eliminates h, find p
7p = $84
p = 84/7
p = $12 for wrap of plain paper
Find h using the 1st original equation
3(12) + 11h = 168
36+ 11h = 168
11h = 168 - 36
11h = 132
h = 132/11
h = $12 for shiny wrapping paper
Therefore each plain wrapping paper costs $12 and each shiny wrapping paper costs same $12 !

What method can be used to prove the triangles below are congruent?
Answers: SAS, AAS, ASA, Not Possible
Answer: D) Not possible
SSA is not a valid congruence theorem. Note how the angles are not between the congruent sides.
An SSA congruence theorem does exist. By SSA congruence ΔABC ≅ ΔPQR. Therefore, option D is the correct answer.
In the given figure, two sides and one angle of one triangle congruent to other triangle.
What is the congruence theorem?Triangle congruence theorem or triangle congruence criteria help in proving if a triangle is congruent or not. The word congruent means exactly equal in shape and size no matter if we turn it, flip it or rotate it.
Consider ΔABC and ΔPQR
Here,

At a party there are 3 pizzas to share. If each pizza has 8 slices, determine how many pieces each child will receive if 12 kids attend the party. Now what if 8 kids attend?
Answer: your answer is 3
Step-by-step explanation: if you multiply 3 and 8 you get 24 divide that by 8.
The number of pizzas each kid will receive if there were 12 children was 2 slices each
The number of pizzas each kid will receive if there were 8 children was 3 slices each
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
The total number of pizzas at the party = 3 pizzas
The total number of slices in 1 pizza = 8 slices
So , the number of slices in 3 pizzas = 3 x 8 slices
The number of slices in 3 pizzas = 24 slices
Now , the equation will be
The number of children attended the party be = A
The value of A = 12 children
So , the number of pizza slices each child gets = number of slices in 3 pizzas / number of children attended the party
Substituting the values in the equation , we get
Number of pizza slices each child gets = 24 / 12
Number of pizza slices each child gets = 2 slices each
Therefore , if there are 12 children , the number of slices of pizzas each child receives is 2 slices
Now , if the number of children is B = 8
Number of pizza slices each child gets = 24 / 8
Number of pizza slices each child gets = 3 slices each
Therefore , if there are 8 children , the number of slices of pizzas each child receives is 3 slices
Hence , The number of pizzas each kid will receive if there were 12 children was 2 slices each
The number of pizzas each kid will receive if there were 8 children was 3 slices each

8.9, 6.1, -4.8, 8.2, 2.7,-0.1
Enter the answer
Answer:
The mean of the given set of numbers is 3.5
Step-by-step explanation:
We need to find the mean of following numbers:
8.9, 6.1, -4.8, 8.2, 2.7,-0.1
For calculating the mean the formula used is: [tex]Mean=\frac{Sum \ of \ all \ numbers}{Total \ numbers}[/tex]
Finding sum of numbers:
[tex]Sum \ of \ numbers= 8.9+6.1-4.8+8.2+2.7-0.1\\Sum \ of \ numbers= 21[/tex]
Total numbers = 6
So, mean is:
[tex]Mean=\frac{Sum \ of \ all \ numbers}{Total \ numbers}\\Mean=\frac{21}{6}\\Mean= 3.5[/tex]
So, mean of the given set of numbers is 3.5

∠A=4x − 17
∠B= 3x + 8
∠C= x+ 13
x = 22
x = 23
x= 176
x = 3.7
Answer:
Step-by-step explanation:
4x-17+3x+8+x+13=180
8x+4 =180
8x=176
X=22
Answer:
x = 22
Step-by-step explanation:
<A + <B + <C = 180
<A = 4x - 17
<B = 3x + 8
<C = x + 13
4x - 17 + 3x + 8 + x + 13 = 180 Collect the like terms
8x + 4 = 180 Subtract 4 from both sides
8x = 180 - 4
8x = 176 Divide by 8
x = 176/8
x = 22

All angles in a triangle add up to 180°Step-by-step explanation:
Step 1: Set up equation
x + 94° + 23° = 180°
Step 2: Solve for x
Combine like terms: x + 117° = 180°Subtract 117° on both sides: x = 63°Answer: it’s 63
Step-by-step explanation:
All triangles equal 180. So you need to add the angles they give you; so 23+94=117 so then you subtract 117 from 180 which equal 63

Answer:
x=20 degrees
Step-by-step explanation:
Line y is a perpendicular bisector making a 90 degree angle with the base of the triangle. The Interior Angle Sum Theorem states that the sum of the interior angles of a triangle is always equal to 180 degrees. Add 70 to 90
70+90=160 degrees
Subtract the sum from 180
180-160=20 degrees
One x is equal to 20 degrees. Both x's are equal to 40 degrees.

Yani buys a certain brand of cereal that costs $10 per box. Yani changes to a super-saving brand of the same size. The equation shows
the price, y, as a function of the number of boxes, x, for the new brand.
y = 7x
Part A: How many more dollars is the price of a box of Yani's original brand of cereal than the price of a box of the super-saving cereal?
Show your work.
Part B: How much money does Yani save each month with the change in cereal brand if he buys 5 cereal boxes each month? Show your
work.
Answer:
A) Original price : y =10.x
Cheaper brand : y = 7x
The original box is $3 more than the cheap one.
Proof: Suppose 1 box is bought of each (x=1),Original will cost $10 & the Cheaper Price is $7
B) Each time he buys a cheap brand he save $3 ($10-$7).
On 5 cheap boxes, He would save $3 x 5 boxes = $15.
Step-by-step explanation:
Part A: The price of the first cereal that Yani bought was $10 and he new cereal is $7.
$10 - $7 = $3. The original box of cereal was $3 more than the super- saving cereal.
Part B: Yani will save $15 each month.
With the $10 cereal he used to pay $50 per month. Now with the super-saving cereal, he will now pay $35 per month.
So we need to subtract $50 - $35 = $15
The answer for part A is Original price: y =10x and Cheaper brand: y = 7x, and for part B he would save boxes $15.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
Yani buys a certain brand of cereal that costs $10 per box.
Yani changes to a super-saving brand of the same size.
= $10 - $7 = $3.
Yani will save $15 each month.
= $50 - $35 = $15
Thus, the answer for part A is Original price: y =10x and Cheaper brand: y = 7x, and for part B he would save boxes $15.
