Part A
x = some unknown number
2x = doubling that number
2x+11 = adding on eleven
Answer: 2x+11 = 25=============================================================
Part B
If we knew what x was, then we can compute 2x+11 using the order of operations PEMDAS. Because x is unknown, we follow PEMDAS in reverse to isolate x.
So we'll undo the addition first by subtracting 11 from both sides. Then we undo the multiplication by dividing both sides by 2.
2x+11 = 25
2x+11-11 = 25-11 ..... subtract 11 from both sides
2x = 14
2x/2 = 14/2 ...... divide both sides by 2
x = 7
The number the person thought of was 7. Double 7 to get 14. Add on eleven to get 14+11 = 25.

Lucy is going to watch a movie in her collection. She has 5 action movies, 4 comedies, and 3 dramas.
She will randomly select one movie. What is the probability that the movie she selects is not a drama?
Write your answer as a fraction in simplest form.
Answer:
3/4
Step-by-step explanation:
5 action+4 comedy+3 drama= 12 total movies
12 will be the denominator of our fraction.
The question asks: What is the probability that the movie she selects is NOT a drama?
So, we add the number of action and comedy movies.
5+4=9
9 is our numerator.
But wait! We have to simplify the fraction 9/12!
9 divided by 3= 3
12 divided by 3= 4
Reduced answer: 3/4

Consider the line y=6/7 x -7. Find the equation of the line that is perpendicular to this line and passes through the point (6,-6). Find the equation of the line that is parallel to this line and passes through the point (6,-6) .
Answer:
[tex]y= -\frac76x +1[/tex]; [tex]y= \frac67x -\frac{78}7[/tex]
Step-by-step explanation:
We know from theory that two perpendicular lines have the product of their slope equal to -1. Let's find the second slope:
[tex]\frac67m = -1 \rightarrow m=-\frac76[/tex]
At this point we can just use the slope-point equation to get our first line:
[tex]y-y_0 = m(x-x_0)\\y-(-6) = -\frac76(x-6) \\y+6= -\frac76x +7\\y= -\frac76x +1[/tex]
Now, we know that two parallel lines have the same slope. Time to apply the same point-slope formula, with the original m this time.
[tex]y-(-6) = \frac67(x-6)\\y+6 = \frac67x -\frac{36}7\\y= \frac67x -\frac{36}7 -{\frac{42}7[/tex]
[tex]y= \frac67x -\frac{78}7[/tex]

Is the function Linear or Nonlinear, and explain why
Explanation:
The variable x increases by 1 each time we move down the rows. This increase is constant or the same jump each time.
However, the variable y increases by different amounts. From y = 2 to y = 6, we have +4. Then from y = 6 to y = 12 is +6. This mismatch of increases is sufficient to prove we don't have a linear function. The function is nonlinear.
Visually, we can plot all of the points on the same xy grid. Notice that a straight line does not go through all four points. Rather, a parabola does, and the equation of the parabola is y = x^2+x which is the same as y = x(x+1).

Morgan drew 3 lines. • Line A moves in the same direction as Line B and the lines never intersect. • Line B forms a perfect right angle (90° angle) with Line C. Which statement is correct about these lines?
A: Line B is parallel to Line
2: Line A is perpendicular to Line B
3: Line C is perpendicular to Line A
4: Line C is parallel to Line A
Answer: line c is perpendicular to line a
Step-by-step explanation:
Parallel lines are two or more lines that lie next to each other
Line C is perpendicular to Line A.
The correct option is 3.
What are parallel and perpendicular lines?Parallel lines are the lines that do not intersect or meet each other at any point in a plane.
In Mathematics, a perpendicular is defined as a straight line that makes the right angle (90 degrees) with the other line. In other words, if two lines intersect each other at the right angle, then the lines are perpendicular to each other.
Given, three lines A, B and C.
Line A moves to the same direction as Line B
⇒ Line A║ Line B
Line B makes perfect right angle with line C
⇒ Line B ⊥ Line C
From the given statements
we can conclude
⇒ Line A ⊥ Line C
Hence, Line C ⊥ Line A

Which of the following is not an advantage of renting? a. Ease of mobility b. Fewer responsibilities c. Lower initial costs d. Restricted lifestyle Please select the best answer from the choices provided A B C D.
A restricted lifestyle is not an advantage of renting.
Option D is the correct answer.
What is renting?Renting a property has several advantages, such as ease of mobility, fewer responsibilities, and lower initial costs.
We have,
Ease of mobility is an advantage because it is easier for renters to move to a new location since they are not tied down to a specific property.
Fewer responsibilities are another advantage because the landlord is usually responsible for maintaining the property, making repairs, and paying for utilities.
This means that renters do not have to worry about these tasks or expenses.
Lower initial costs are also an advantage because renters do not have to pay for a down payment or closing costs, which can be a significant expense when purchasing a property.
A restricted lifestyle is not an advantage of renting.
This is because renters may be limited in terms of decorating, making changes to the property, or having pets.
Renters may also have to abide by certain rules set by the landlord or property management company.
This can limit their freedom and personalization of the space.
Thus,
A restricted lifestyle is not an advantage of renting.

Find the measure of X
Answer:
x = 6
Step-by-step explanation:
When parallel lines are intersected by a transversal
alternate exterior angles are congruent
Therefor
15(x + 2) = 120
Divide both sides by 15
x + 2 = 8
Subtract 2 from both sides
x = 6
Answer:
Step-by-step explanation:
here 120 degrees would be the same as 15(x+2)
Just like how angle R on the other side of 120 Degrees is the same
so 15(x+2) = 120 degrees
let us distribute
15x +30 = 120
-30 -30
15x=90
15x/15=90 /15
x=6

7. Elle can buy milk at a local farmers'
market for $3.58 per gallon or at the
grocery store for $3.79 for 4 L. Which
is the better buy?
Answer: They are the same equivalent price, $0.95/liter.
Step-by-step explanation:
Choices: $3.58 per gallon, or $3.79 for 4 L.
========
We need to convert one of the volumes. I'll convert gallons to liters.
By definition, 1 gallon = 3.785 liters
Make this into a conversion factor:
We can make it either:
1) (3.785 liters/gallon), or
2) (1 gallon/3.785 liters)
Now convert the $3.58/gallon into dollars/liter. We'll use the second conversion factor so that gallons cancels out when we multiply:
($3.58/gallon)*(1 gallon/3.785 liters) = $0.95/liter.
The grocery store milk must also be converted to a price expressed per 1 liter:
$3.79 for 4 L
= $0.95/liter.
They are the same equivalent price, $0.95/liter.

Theresa created a piece of art by attaching a square plank to a triangular plank. The square plank has a perimeter of 48 inches. The triangular plank has a base length of 12 inches and a height of 6 inches. She wants to cover the piece of art with colored paper.
How many square inches of paper are needed to cover Theresa's art piece?
Answer:
180
Step-by-step explanation:
Answer:
180
Step-by-step explanation:
The perimeter of the square is 48. The Square has 4 sides so 48/4 = 12.
One side of the square is 12. Use [tex]12^{4}[/tex] to calculate the area. [tex]12^{4}[/tex] = 144.

-a/6 + 7 = -14 I want to know how to do this
Step-by-step explanation:
so, if you did not make a typo the problem is
-a/6 + 7 = -14
and I guess, you need to find the value of a to make this equation true. right ?
you know that you can do additional operations on the equation ?
the rule is, whatever you change on one side of the equation you have to change also on the other side (otherwise we would destroy the original equation, where the left side must be equal to the right side).
so, a good idea to start is to try and separate the terms with the variable and the constants.
so, let's subtract 7 from both sides :
-a/6 = -14 - 7 = -21
next, the fraction is disturbing. let's dissolve it by multiplying both sides by 6 :
-a = -21×6 = -126
both sides are negative expressions. that is not nice either. let's multiply both sides by -1
a = 126
and we have our result ! bingo !
Can you solve this? Thank you
Answer:
14
Step-by-step explanation:
ratio of red : blue = 4 : 3 = 4x : 3x ( x is a multiplier )
8 red counters are added , so
4x + 8 : 3x = 8 : 3
Expressing the ratio in fractional form
[tex]\frac{4x+8}{8}[/tex] = [tex]\frac{3x}{3}[/tex] ( cross- multiply )
24x = 3(4x + 8) = 12x + 24 ( subtract 12x from both sides )
12x = 24 ( divide both sides by 12 )
x = 2
original number of counters = 4x + 3x = 7x = 7(2) = 14
