Kevin and Brittany write an equation to represent the following relationship, and both students solve their equation. Who found the correct equation and solution? Why is the other person incorrect?
6 times the difference of a number and 20 is the same as half the sum of 8 more than 8 times a number.
Kevin: 6(x − 20) =

(8x + 8) 6x − 120 = 4x + 4 6x − 120 − 4x = 4x + 4 − 4x 2x − 120 = 4 2x − 120 + 120 = 4 + 120 2x = 124

x = 62 Brittany: 6(20 − x) =

(8x + 8) 120 − 6x = 4x + 4 120 − 6x − 4x = 4x + 4 − 4x 120 − 2x = 4 120 − 2x − 120 = 4 − 120 −2x = −116

Solve the equation: 2/3y+5=7/3y-10
Answer:
y = 9
Step-by-step explanation:
2/3y + 5 = 7/3y - 10 ( Rearrange expression )
2/3y - 7/3y = -10 -5 ( Combine like terms )
-5/3y = -15 ( Divide )
y = 9

Find the mean, median, and mode of 13, 30, 16, 19, 20, 22, 25, 31
Answer:
Mean: 22
Median: 21
Mode: No mode
Step-by-step explanation:
Mean:
The sum is the value of all the values divided by the number of values:
[tex]13+30+16+19+20+22+25+31/8[/tex] which is 22.
Median:
The median is the middle-most value of the data set when arranged from lowest to highest:
13, 16, 19, 20, 22, 25, 30, 31
Here, since there are two middle-most terms, the median would be the average of 20 and 22 (20+22/2), which is 21.
Mode:
The mode is the most occurring value in the data set.
13, 16, 19, 20, 22, 25, 30, 31
Since, in this data set, there is do value that occurs twice, we can say that there is no mode for this data set.

4-3x=2x-11
solve for x
Answer:
x=3
Step-by-step explanation:
So first thing you are going to want to do is move like terms to the same side.
4-3x=2x-11
4+11=2x+3x
Signs get switched when moved.
Then you combine the like terms.
4+11=2x+3x
15=5x
Do a quick little switch of sides (this doesn't effect anything in the equation, just makes it easier to look at)
5x=15
Then to get rid of the exponent on the variable (the 5 in front of the x) you divide out the exponent on BOTH SIDES
(Remember what you do to one side of the equation you have to do to the other)
5x=15
x=3
Help! i don’t understand this Question!
Answer:
h = 2.5
Step-by-step explanation:
This question deals with a translation applied to the parent function, f(x) = |x|.
The parent function of the absolute value equation is f(x) = |x|. The graph of f(x) = |x| is a V-shaped graph as shown in the graph, but the vertex of the V is at (0, 0).
When you substitute x - h for x, you translate the parent function h units horizontally. When you substitute y - k for y, you translate the parent function k units vertically.
Think of the parent function described above, f(x) = |x|.
Its vertex is at the origin, (0, 0).
Now look at the function in your graph. It is a horizontal and vertical translation of the parent function since the vertex is now at (2.5, 1.5).
The horizontal translation was from x = 0 to x = 2.5, so h is 2.5.
As mentioned above, when you substitute x - h for x, you translate the function h units horizontally. Since the horizontal translation is 2.5, h = 2.5.
Answer: h = 2.5
inclusive of a 6.7% sales tax, a simone ring sold for $1707.20. Find the price of the ring before the tax was added.
The price of the ring before the tax was added is $1,600.
What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
The price of the ring before the tax was added is,
106.7% ( x ) = 1707.20
( x ) = 1707.20/106.7
( x ) = 16
( x ) = 16x100 = $1,600
Therefore, the price of the ring before the tax was added is $1,600.

Evaluate 1/6 + 2/3

B. 3/18
C. 5/6
D. 1 1/6
Answer:
5/6
Step-by-step explanation:
Evaluate f(x) = x2 for f(-8).
On evaluating the function at x = -8, we get -
f(-8) = 64.
We have a function -
f(x) = [tex]x^{2}[/tex]
We have to find the value of f(x) at x = -8.
Evaluate - f(x) = Sin( [tex]\frac{\pi }{x}[/tex] ) at x = 4.f(x) = Sin( [tex]\frac{\pi }{x}[/tex] )
f(4) = Sin( [tex]\frac{\pi }{4}[/tex] )
f(4) = [tex]\frac{1}{\sqrt{2} }[/tex]
According to the question, we have -
f(x) = [tex]x^{2}[/tex]
Now, evaluating the function at x = -8, we get -
f(- 8) = [tex](-8)^{2}[/tex] = -8 x -8 = 64
Hence, on evaluating the function at x = -8, we get -
f(-8) = 64.

Sherry claims that the expression 1/x will always be equivalent to a repeating decimal whenever x is an odd number greater than 1
Answer:
The correct options are :
b. 5
e. 25
Step-by-step explanation:
The question is incomplete. The missing part is :
'' Which of these values will prove Sherry's claim is false :
a. 3
b. 5
c. 7
d. 11
e. 25 ''
One way to prove that Sherry's claim is false is finding one odd number greater than 1 that when we replace it in the denominator of the expression [tex]\frac{1}{x}[/tex] the result isn't equivalent to a repeating decimal.
Let's analyze each option :
a. 33 is an odd number greater than 1 ⇒ If we replace in the expression [tex]\frac{1}{x}[/tex] ⇒
[tex]\frac{1}{3}[/tex] ≅ 0.3333 (repeating decimal)
The option a. 3 won't prove that Sherry's claim is false.
b. 55 is an odd number greater than 1 ⇒ If we replace in the expression [tex]\frac{1}{x}[/tex] ⇒
[tex]\frac{1}{5}=0.2[/tex]
The result isn't a repeating decimal.
The option b. 5 will prove that Sherry's claim is false.
c. 77 is an odd number greater than 1 ⇒ If we replace in the expression [tex]\frac{1}{x}[/tex] ⇒
[tex]\frac{1}{7}[/tex] ≅ 0.1428 (repeating decimal)
The option c. 7 won't prove that Sherry's claim is false.
d. 1111 is an odd number greater than 1 ⇒ If we replace in the expression [tex]\frac{1}{x}[/tex] ⇒
[tex]\frac{1}{11}[/tex] ≅ 0.0909 (repeating decimal)
The option d. 11 won't prove that Sherry's claim is false.
e. 2525 is an odd number greater than 1 ⇒ If we replace in the expression [tex]\frac{1}{x}[/tex] ⇒
[tex]\frac{1}{25}[/tex] ≅ 0.04
The result isn't a repeating decimal
The option e. 25 will prove that Sherry's claim is false.

Step-by-step explanation:
The price for strawberries is currently $ 6.40 per pack. next week,strawberries will be on sale at a 20% discount. what is the total price you would pay for 2 1/2 packs of strawberries next week?
Answer:
answer is $5.12
Step-by-step explanation:
Using the formula two and replacing the given values:
Sale Price = Original Price - Amount Saved. So,
Sale Price = 6.40 - 1.28
Sale Price = $5.12 (answer)
This means, the cost of the item to you is $5.12.
You will pay $5.12 for an item with original price of $6.40 when discounted 20%. In other words, if you buy an item at $6.40 with 20% discounts, you pay $6.40 - 1.28 = $5.12
Suppose Have you received a amazon promo code of 1.28. If the price is $6.40 what was the amount saved in percent:
3) 1.28 is what percent off $6.40?
Using the formula two and replacing the given values:
Amount Saved = Original Price x Discount % /100. So,
1.28 = 6.40 x Discount % / 100
1.28 / 6.40 = Discount % /100
100 x 1.28 / 6.40 = Discount %
128 / 6.40 = Discount %, or
Discount % = 20 (answer)
