Megan buys 3 bracelets and 3 necklaces each bracelet cost in dollars of one necklace?
Answers
Here's our equation: 3x+15=36
Now solve: First subtract 15 from both sides of the equation to keep it balanced and to separate the variable from the constants.
3x+15-15=36-15
3x=21
Next divide both sides by 3.
3x/3=21/3
x=7
You can check if this is right by going back to the word problem. 3 bracelets $5 each = 15. 3 necklaces $7 each = 21. 21+15=36. If she pays $40, 40-36-= $4 in change.
Each necklace is $7

If 5a=-4b+5 and 3a=-2b+3, what is 6b?
Answers
5a = -4b + 5
3a = -2b + 3
You can multiply the second equation by two, so the 4b and -4b in both equations will cancel each other out when you add them. So:
5a = -4b +5
6a = 4b +6
Add both equations together.
11a = 11
a = 1
Plug in the a value into any of the previous equations:
5(1) = -4b + 5
-4b = 0
b = 0
So, since we know that b = 0, 6b is also 0.
What series of transformations to quadrilateral ABCD map the quadrilateral onto quadrilateral EFGH to prove that ABCD≅EFGH ?
a reflection across x-axis, and then a translation 4 units left
a reflection across x-axis, and then a translation 4 units right
a reflection across y-axis, and then a translation 4 units right
a reflection across y-axis, and then a translation 4 units left
Answers
Comparing the points to their mapped images compares A to E, B to F, C to G, and D to H. In each point, the y-coordinate switches signs and the x-coordinate is subtracted by 4.
Reflections across the x-axis will switch the sign of the y-coordinate, and reflections across the y-axis will switch the sign of the x-coordinate. Since the y-coordinates are the ones whose sign changed, the points must have been reflected across the x-axis.
Translations to the left will cause the x-coordinate to increase, and translations to the right will case the x-coordinate to decrease. Since the x-coordinate of every point was subtracted, this means that the translation must have been to the right.
The correct series of transformations is a reflection across the x-axis, and then a translation 4 units left.
Let's start by labeling the vertices of quadrilateral ABCD as follows:
A(2, 4)
B(4, 5)
C(5, 4)
D(4, 1)
If we reflect quadrilateral ABCD across the x-axis, the new coordinates of the vertices will be:
A'(2, -4)
B'(4, -5)
C'(5, -4)
D'(4, -1)
Now, if we translate quadrilateral A'B'C'D' 4 units left, the new coordinates of the vertices will be:
E(-2, -4)
F(0, -5)
G(1, -4)
H(0, -1)
These are the coordinates of the vertices of quadrilateral EFGH.
Therefore, it can prove that for the transformation to quadrilaterals ABCD≅EFGH by reflecting quadrilateral ABCD across the x-axis and then translating it 4 units left.

Answers
The polling methods likely to be biased are when Option d. Five of Janine's friends are selected and asked for whom they intend to vote.
When conducting a poll, it is important to ensure the sampling method is random and representative. Here are the methods and their potential biases:
Janine chooses 5 members that plan on voting for her and asks each to select another 5 members. These 25 members are asked for whom they intend to vote. — This method is likely to be biased because it relies on the initial selection of supporters, which creates a non-random and unrepresentative sample.Every 10th club member from a list of all members is selected and asked for whom the member intends to vote. — This method is less likely to be biased as it uses systematic sampling, which is more representative of the entire population.From a list of all club members, 25 members are selected at random and asked for whom they intend to vote. — This method is unlikely to be biased because it employs a simple random sample, ensuring each member has an equal chance of being selected.Five of Janine's friends are selected and asked for whom they intend to vote. — This method is likely to be biased due to the convenience sampling of her friends, which is not representative of the entire club.Hence option D is likely to be biased.

The clothes are brought for $50
The selling price is $80
% Change Formula=(Selling price / cost price ) ÷ cost price# x 100

stacy has hired tom to build her a doll house. The doll house will be a scale model of her home, and the scale will be 2 inches:3ft. The living room in stacy's house is 18 feet by 12 feet and has wall-to-wall carpeting. Hiw many square inches of carpeting will Tom need for thevliving room in Stacy's doll house?
Answers
To find the area of the living room in Stacy's doll house, we need to use the given scale of 2 inches:3ft.
Explanation:To find the area of the living room in Stacy's doll house, we need to use the given scale of 2 inches:3ft. First, we convert the dimensions of the living room from feet to inches. The dimensions of the living room in inches will be 18 feet * 12 inches/foot = 216 inches by 12 feet * 12 inches/foot = 144 inches.
Next, we multiply the dimensions by the scale factor of 2 inches:3ft. The dimensions of the living room in the doll house will be 216 inches * (2 inches/3ft) = 144 inches and 144 inches * (2 inches/3ft) = 96 inches.
Finally, we multiply the dimensions together to find the area: 144 inches * 96 inches = 13,824 square inches.

What is the slope of this line?
Answers
To find slope, calculate the change in y-values and divide it by the change in x-values:
y1 - y2 / x1 - x2
You have the coordinates (-4, 5), (0, 6), and (8, 8). You can use any combination of two of these points to calculate slope. I'll use (0, 6) and (8, 8).
6 - 8 / 0 - 8
-2 / -8
1/4
Answer:
The slope of the line is 1/4
y2 = 8
y1 = 6
x2 = 8
x1= 0
That makes the problem 8 - 6/ 8 - 0. Let's subtract. 8 - 6 is 2. 8 - 0 is 8. 2/8 is 1/4 in simplest form. There. The slope of the line is 1/4.

plz help
Answers
The triangle inequality theorem states that any two sides of a triangle must have a sum greater than the third side. Given the two sides we have, 7 and 4, the sum would be 11; this would mean that the missing side could be no more than 10.
If we take the unknown side and the smallest one we're given, we would have the inequality
n+4>7
Subtracting 4 from both sides we would have n>3. That means it would have to be the next integer up, which would be 4.
Smallest value and largest value of n is [tex]11 , 3[/tex].
The third side of a triangle has a range,
[tex]Sum\; of \;two\; other\; sides\geq n\geq Difference\; of\; the\; sides[/tex]
[tex]7+4\geq n \geq7-4[/tex]
[tex]11\geq n \geq 3[/tex]

Yolanda participated In a walkathon in which each kilometer walked raised $10 for charity, her goal was to raise more more than $300 on Saturday and Sunday she raised $50 on Saturday which inequality is it?
Answers
50+x(greater or equal to)300
Answer: The required inequality will be 50+x>$300
Step-by-step explanation:
Since we have given that
Amount raised for charity = $10
Amount raised on Saturday = $50
Amount raised on both Saturday and Sunday is more than $300.
Let the amount raised on Sunday be 'x'.
So, Inequality becomes,
Saturday + Sunday > $300
50+x>$300
x>$300-$50
x>$250
So, On Sunday he must raised more than $250.
Hence, the required inequality will be
50+x>$300
