What value of x makes this equation true?
2x = 4x – 10
Answer:
5
Step-by-step explanation:
2x = 4x - 10
4x - 2x = 10
2x = 10
x = 10/2
X = 5
2(5) = 4(5) - 10
10 = 20-10
10=10
Answer:
x = 5
Step-by-step explanation:
put x on one side (subtract the x on the left from both sides)
-2x = -10
divide the extra number with the x from both sides
x = 5
hope this helps!

Solve the following equation by completing the square.
A.
B.
C.
D.
Answer:
x = 2 + sqrt(2) or x = 2 - sqrt(2) thus B. is your answer
Step-by-step explanation:
Solve for x over the real numbers:
4 x^2 - 16 x + 8 = 0
Hint: | Write the quadratic equation in standard form.
Divide both sides by 4:
x^2 - 4 x + 2 = 0
Hint: | Solve the quadratic equation by completing the square.
Subtract 2 from both sides:
x^2 - 4 x = -2
Hint: | Take one half of the coefficient of x and square it, then add it to both sides.
Add 4 to both sides:
x^2 - 4 x + 4 = 2
Hint: | Factor the left-hand side.
Write the left-hand side as a square:
(x - 2)^2 = 2
Hint: | Eliminate the exponent on the left-hand side.
Take the square root of both sides:
x - 2 = sqrt(2) or x - 2 = -sqrt(2)
Hint: | Look at the first equation: Solve for x.
Add 2 to both sides:
x = 2 + sqrt(2) or x - 2 = -sqrt(2)
Hint: | Look at the second equation: Solve for x.
Add 2 to both sides:
Answer: x = 2 + sqrt(2) or x = 2 - sqrt(2)

Solve for X. Show your work.
Answer:
x=9
Step-by-step explanation:
since the location of 4x+2 and 7x-25 is across from each other that means that they are equal to each other so you have to set them equal to each other by doing 4x+2=7x-25 then you add like terms you add 25 and 2 together which gives you 27 and the equation will look like 4x+27=7x and then you subtract 4x from 7x which gives you 3x and u get the equation 27=3x now you divide 27 by 3 and get 9 so the equation will be x=9

Q. Mary lost 30 pounds. Before her diet she weighed 180 pounds. What is the
percent of change?
Answer:
16.67%
Step-by-step explanation:
A fraction consists of two numbers and a fraction bar:
30/180
The number above the bar is the numerator: 30
The number below the bar is the denominator: 180
Divide the numerator by the denominator to get fraction's value:
Val = 30 ÷ 180
30/180=16.666666667
16.666666667= 16.67%
Answer:

What are Combinations?The number of ways of selecting r objects from n unlike objects is given by combinations
ⁿCₓ = n! / ( ( n - x )! x! )
where
n = total number of objects
x = number of choosing objects from the set
Given data ,
If A, B, C, and D are different points on the same line, then the number of line segments with endpoints at these points can be calculated by counting the number of ways to choose 2 points from the 4 points.
The number of ways to choose 2 points from 4 points is given by the binomial coefficient 4 choose 2, which is:
So , the combination is ⁴C₂
4 choose 2 = ⁴C₂ = (4!)/(2!(4-2)!) = (4 x 3)/(2 x 1) = 6
Hence , there are 6 line segments with endpoints at A, B, C, and D.

SA−→ bisects ∠RST and m∠RST=54.2∘. Find m∠RSA and m∠AST.
Answer:
m∠RSA is 27.1° and m∠AST is 27.1°
Step-by-step explanation:
If a ray bisects an angle, then it divides it into two equal angles in measures and the measure of each one is half the measure of this angle
In the given question
∵ Ray SA bisects ∠RST
→ That means it divides it into two angles RSA and AST
∴ m∠RSA = m∠AST = [tex]\frac{1}{2}[/tex] m∠RST
∵ m∠RST = 54.2°
→ Multiply its measure by to find the measures its parts
∴ m∠RSA = [tex]\frac{1}{2}[/tex] × 54.2°
∴ m∠RSA = 27.1°
∴ m∠AST = [tex]\frac{1}{2}[/tex] × 54.2°
∴ m∠AST = 27.1°

A study investigated about 3000 meals ordered from Chipotle restaurants using the online site Grubhub. Researchers calculated the sodium content (in milligrams) for each order based on Chipotle's published nutrition information. The distribution of sodium content is approximately Normal with mean 2000 mg and standard deviation 500 mg. About what percent of the meals ordered exceeded the recommended daily allowance of 2400 mg of sodium?
Answer:
21.186%
Step-by-step explanation:
z = (x-μ)/σ,
where
x is the raw score = 2400mg
μ is the population mean = 2000mg
σ is the population standard deviation = 500mg
z = 2400 - 2000/500
z = 0.8
Probability value from Z-Table:
P(x<2400) = 0.78814
P(x>2400) = 1 - P(x<2400) = 0.21186
Converting to percentage:
0.21186 × 100
= 21.186%
Therefore, the percent of the meals
ordered that exceeded the recommended daily allowance of 2400 mg of sodium is 21.186%
21.186% of the meals ordered exceeded the recommended daily allowance of 2400 mg of sodium.
It is known that 3000 meals ordered from Chipotle restaurants using the online site Grubhub.
And the distribution of sodium content is approximately Normal with mean 2000mg and standard deviation 500 mg.
We know,
[tex]z = \frac{(x- \mu)}{\(\sigma\)}[/tex],
And daily allowance of 2400 mg of sodium
x is the raw score = 2400mg
μ is the population mean = 2000mg
σ is the population standard deviation = 500mg
[tex]z = \frac{2400 - 2000}{500}[/tex]
z = 0.8
Probability value from Z-Table:
[tex]P(x<2400) = 0.78814\\P(x>2400) = 1 - P(x<2400) \\= 0.21186[/tex]
Converting to percentage:
[tex]= 0.21186 (100)\\= 21.186%[/tex]
Therefore, the percent of the meals ordered that exceeded the recommended daily allowance of 2400 mg of sodium is 21.186%.

Which is a factor of 6x2 x − 7? x 1 2x 1 6x 7 3x 7
The factor of the polynomial 6x² + x − 7 using factorization is (x − 1) and (6x + 7). Then the correct option is C.
What is a factorization?It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.
The polynomial is given as 6x² + x − 7
On factorization, we have
6x² + x − 7
6x² + 7x − 6x − 7
x (6x + 7) −1 (6x + 7)
(x − 1)(6x + 7)

Shaun's parents agreed to pay 2/5 of the cost of a
bike, if he was able to save the rest. If his parents
gave him $92, how much did the bike cost?
Answer:
The bike was $230
Step-by-step explanation:
If 2/5 is $92 you can divide 92 by two like so,
92 ÷ 2 = 46
So ONE fifth is 46 to find out the total (5/5) you multiply by 5 so it would turn up like this,
46 × 5 = 230
The bike was $230
