Answer:
I think they are both wrong
The correct way to solve it is this.
Step-by-step explanation:
Step 1: Subtract 4 from both sides.
[tex]-6x+4-4=-20-4[/tex]
[tex]-6x=-24[/tex]
Step 2: Divide both sides by -6.
[tex]\frac{-6x}{-6} =\frac{-24}{-6}[/tex][tex]x=4[/tex]
Answer:
x=4

This is a problem of equation part of Algebra.
Some important Algebra formulas.
(a + b)² = a² + 2ab + b²
(a − b)² = a² − 2ab − b²
(a + b)³ = a³ + 3a²b + 3ab² + b³
(a - b)³ = a³ - 3a²b + 3ab² - b³
a³ + b³ = (a + b)³ − 3ab(a + b)
a³ - b³ = (a -b)³ + 3ab(a - b)
a² − b² = (a + b)(a − b)
a² + b² = (a + b)² − 2ab
a² + b² = (a − b)² + 2ab
a³ − b³ = (a − b)(a² + ab + b²)
a³ + b³ = (a + b)(a² − ab + b²)
Here given, equation is [tex] - 6x + 4 = - 20[/tex]
Now,
-6x + 4 = -20
First we are separating variable and constant part.
So first we subtracting 4 from (-20) and get
[tex] - 6x = - 20 - 4[/tex]
or,[tex] - 6x = - 24[/tex]
Now (-24) is dividing by (-6) and get,
[tex]x = \frac{ - 24}{ - 6} \\ x = 4[/tex]
So, value of x is 4.

Topic: The Pythagorean Theorem and Its Converse
State if the three sides lengths form a right triangle.
13) 10cm, 49.5cm, 50.5cm
(I NEED HELP PLZ SHOW WORK)
I WILL GIVE BRIANLIEST
Answer:
Yes, this is a right triangle.
Step-by-step explanation:
The Pythagorean Theorem states that if the sum of the squares of the two small sides of a triangle add up to the square of the longest side, then the triangle is a right triangle: a² + b² = c², where a and b are the smallest sides (called legs) and c is the longest side (called the hypotenuse).
Here, the two smallest sides are 10 and 49.5, so let's square them, add them up, and see if they add up to 50.5²:
10² = 100
49.5² = 2450.25
100 + 2450.25 = 2550.25
50.5² = 2550.25
Since 10² + 49.5² equals 50.5², we know that this is a right triangle.
Thus, yes, this is a right triangle.

Find the value of y. Use 3.14

Answer is 11.046
Explanation :
The formula is pie × r² × height
If you don't understand.. Lemme know ya
A circular flower bed is 22 m in diameter and has a circular sidewalk around it that is 4 m wide. Find the area of the sidewalk in square meters. Use 3.14 for pi
Answer:
326.6 m^2
to nearest tenth.
Step-by-step explanation:
The radius of the flower bed = 1/2 * 22 = 11m
The radius of the whole area included the sidewalk = 11 + 4 = 15 m
So the area of the sidewalk = area of the whole - area of flower bed
= 3.14 * 15^2 - 3.14* 11^2
= 326.6 m^2.
Write an equation for the nth term of the geometric sequence below: (Equation NEEDS to be written as gn=7(5)^(n-1) or as gn=2/3(1/4)^(n-1) NOTICE NO SPACES & using ^ to represent an exponent)
Answer:
You didn't give the geometric sequence in question.
But to find the nth term of a geometric sequence, use the formula
Sn = ar^(n - 1)
Where a is the first term of the sequence
r is the common ratio of the sequence.
Example: To find the nth term of the geometric sequence
1/2, 1/4, 1/8, 1/16, ...
Here, a = 1/2
r = 1/4 ÷ 1/2 = 1/8 ÷ 1/4 = 1/16 ÷ 1/8 = 1/2.
Sn = (1/2)(1/2)^( n - 1)
Apply this method to the sequence you were given, it will be helpful.

A normal distribution has mean and standard deviation . Find the indicated probability for a randomly selected x-value from the distribution P (x > +3)
Answer:
0.0228
Step-by-step explanation:
Let us assume that the mean (μ) = 2 and the standard deviation (σ) = 0.5
Z score is a standard score used to measure the number of standard deviations by which the raw score (x) is above or below the mean. It is given by the equation:
[tex]z=\frac{x-\mu}{\sigma}[/tex]
For x > 3
[tex]z=\frac{x-\mu}{\sigma} =\frac{3-2}{0.5}=2[/tex]
From the normal distribution table, P(x > 3) = P(z > 2) = 1 - P(z < 2) = 1 - 0.9772 = 0.0228
How many unique ways are there to arrange the letters in a word OPAL.
Answer:
24.
Step-by-step explanation:
We can use the factorial function to find the number of unique arrangements in a word.
There are 4 unique characters in 'OPAL'. As such, 4! = 24.
In the case that there were repeating characters, such as 'OPALA', then we would divide by the factorial of the number of repeating letters. That looks something like this:

Solve for g.
8g + 3 = –6g + 13g + 13
Answer: g = 10
Step-by-step explanation: 8g + 3 = –6g + 13g + 13
8g + 3 = (–6g + 13g) + (13)
8g + 3 = 7g + 13
8g + 3 - 7g = 7g + 13 - 7g
g + 3 = 13
g + 3 - 3 = 13 - 3
g = 10
Answer:
[tex]8g + 3 = -6g + 13g + 13 : g = 10[/tex]
Step-by-step explanation:
[tex]8g+3=-6g+13g+13[/tex]
Add similar elements: [tex]-6g+13g=7g[/tex]
[tex]8g+3=7g+13[/tex]
Subtract [tex]3[/tex] from both sides:
[tex]8g+3-3=7g+13-3[/tex]
Simplify:
[tex]8g=7g+10[/tex]
Subtract [tex]7g[/tex] from both sides:
[tex]8g-7g=7g+10-7g[/tex]
Simplify:
[tex]g=10[/tex]

The units pf the digits of a two digits numeral is 8 if the digits are reversed the new number is 18 greater than the oringal number fund the oringal numeral
complete question:
The sum of the digits of a two-digit numeral is 8. If the digits are reversed, the new number is 18 greater than the original number. How do you find the original numeral?
Answer:
The original number is 10a + b = 10 × 3 + 5 = 35
Step-by-step explanation:
Let
the number = ab
a occupies the tens place while b occupies the unit place. Therefore,
10a + b
The sum of the digits of two-digits numeral
a + b = 8..........(i)
If the digits are reversed. The reverse digit will be 10b + a. The new number is 18 greater than the original number.
Therefore,
10b + a = 18 + 10a + b
10b - b + a - 10a = 18
9b - 9a = 18
divide both sides by 9
b - a = 2...............(ii)
a + b = 8..........(i)
b - a = 2...............(ii)
b = 2 + a from equation (ii)
Insert the value of b in equation (i)
a + (2 + a) = 8
2a + 2 = 8
2a = 6
a = 6/2
a = 3
Insert the value of a in equation(ii)
b - 3 = 2
b = 2 + 3
b = 5
The original number is 10a + b = 10 × 3 + 5 = 35

point C is (negative 2, 2),
point D is (negative 3, negative 3),
point E is (0, 3),

A coordinate geometry has 4 quadrants, in the first Quadrant the x and y axis values are positive.
In second quadrant the coordinates are (-x, y)
In third quadrant the coordinates are (-x, -y)
In fourth quadrant the coordinates are (x, y)
A is in Quadrant I is true
D is in Quadrant III is true
F is on the x axis is true.
Hence, the statements A is in Quadrant I is true, D is in Quadrant III is true and F is on the x axis is true.

No replacement since you ate it
four apples and seven peaches = 11 total
P( peach) = number of peach / total
