Answer:
x<−2
Step-by-step explanation:
−3(−7x−6)−7<x−29
Step 1: Simplify both sides of the inequality.
21x+11<x−29
Step 2: Subtract x from both sides.
21x+11−x<x−29−x
20x+11<−29
Step 3: Subtract 11 from both sides.
20x+11−11<−29−11
20x<−40
Step 4: Divide both sides by 20.

8 + 7x =8x+1
Answer choices: 9,-7, 7, -9
Answer:
Step 1: Simplify both sides of the equation.
7x+8=8x+1
Step 2: Subtract 8x from both sides.
7x+8−8x=8x+1−8x
−x+8=1
Step 3: Subtract 8 from both sides.
−x+8−8=1−8
−x=−7
Step 4: Divide both sides by -1

Answer:
x = 8
Step-by-step explanation:
remember:
When two triangles are congruent they will have exactly the same three sides and exactly the same three angles.
The equal sides and angles may not be in the same position (if there is a turn or a flip), but they are there.
based on the figure given:
AB=8 is also equal to BC=x=8
therefore, your x value would be 8

If RS = 17, ST = x + 6, and RT = 3x - 5, What is ST.
Answer:
ST = 20
Step-by-step explanation:
Line segment RS and segment ST must add up to line segment RT
Step 1: Define
RS = 17
ST = x + 6
RT = 3x - 5
Step 2: Set up equation
mRS + mST = mRT
17 + x + 6 = 3x - 5
Step 3: Solve for x
x + 23 = 3x - 5
23 = 2x - 5
28 = 2x
x = 14
Step 3: Find mST
ST = x + 6
ST = 14 + 6
ST = 20

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)
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.

PLEASE HELP I WILL MARK YOU BRAINLIEST PLEASE In a school of 250 students, 4/5 live within 2 miles of the school. How many students live farther than 2 miles from the school?
Answer:
I'm pretty sure its 50 because 1/5 of 250 is 50
Answer:
50 students
Step-by-step explanation:
when you multiply 250 by 4/5 it gives you how many live within the 2 miles so subtract that number from the total and you get the 50 student who live farther.

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

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.
