you are buying decorations for a birthday party. the before tax total for 3 rolls of crepe paper and 20 balloons is $11.40. after you start decorating, you need more supplies. you buy 2 more rolls of crepe paper and 10 more balloons for $7.20 before tax. how much did each cost?
please help with an explanation.
Answer & Step-by-step explanation:
Let's have
C = Creepers
B = Balloons
1) 6C + 20B = 11.9
2) 2C + 15B = 6.05
Eliminate
16C + 20B = 11.9 x3
-2C + 15B = 6.05 x4
18C + 60B = 35.7
-8C + 60B = 24.2
10C/10 = 11.5/10
C = 1.15

6 is what percent of 9?
Answer:
33 1/3 %
Step-by-step explanation:
6/9 = 1/3 = 33 1/3 %
Hope that helps!
The 6 is approximately 66.67% of 9.
To calculate what percent 6 is of 9, we can use the following formula:
Percent = (Part / Whole) * 100
In this case, 6 is the part and 9 is the whole. Substituting these values into the formula:
Percent = (6 / 9) * 100
To simplify, we divide 6 by 9:
Percent = (2 / 3) * 100
Multiplying 2/3 by 100:
Percent = (2 * 100) / 3
Percent = 200 / 3
To express the result as a decimal:
Percent ≈ 66.67
Therefore, 6 is approximately 66.67% of 9.

The area of the polynomial is 35 square unit.
Step-by-step explanation:
It is given that area of the polygon WXYZ with its vertices at W(–3, –2), X(–3, 5), Y(2, 5), and Z(2, –2)
From the below graph it is noticed that the given polynomial is a rectangle with length 5 and width 7
The distance formula
Using the above formula we get,
The length of opposing sides are equal
Using the Pythagoras theorem, the length of diagonal WY and XZ are
Since the length of the diagonal are same, therefore the given polygon is a rectangle.
The area of a rectangle is
Where l is length and w is width.
The area of given polynomial is
Therefore the area of the polynomial is 35 square unit.

Determine how (if possible) the triangle can be proven similar:
Answer:
Not similar
Step-by-step explanation:
You can only find the vertical angles at the intersection.
So, you know they share one angle.
That is not enough information to prove similarity.
Therefore, I'd say they're not similar.
Chris bought 2 chicken sandwiches and 3 bowls of vegetable soup for $16.50. Jim bought 1 chicken sandwich and 2 bowls of vegetable soup for $9.50. What was the cost of a bowl of soup? A) $4.50 B) $2.50 C) $5.50 D) $3.25
Answer:
Step-by-step explanation:
This is a system of equations, best solved by using the elimination method. But first we have to come up with our 2 equations that represent the system. Let's call the chicken sandwiches "c" and the bowls of soup "b".
If Chris bought 2 chicken sandwiches and 3 bowls of soup for $16.50, his equation is:
2c + 3b = 16.50
If Jim bought 1 sandwich and 2 bowls of soup for $9.50, then his equation is:
1c + 2b = 9.50
We put these together, one above the other, lining up the variables:
2c + 3b = 16.50
1c + 2b = 9.50
If we multiply the second equation by -2 we can eliminate the c variable. Multiplying the second equation by -2 changes only that equation, making the "new" system:
2c + 3b = 16.50
-2c - 4b = -19.00
When we add straight down each column, the c's cancel each other out (they subtract away) and in the b column we have -1b, and in the answer column, we have -2.50.
That equation is -b = -2.50 or b = 2.50
A bowl of soup costs $2.50, choice B
