Please help ! Given m || n, find the value of x. (9x-7)°=(7x3)° … I don’t understand this I’ll love the help. From anyone. Thank youu
Check the picture below.
Answer:
x = 2
Step-by-step explanation:
When a transversal crosses parallel lines, it creates 8 angles. Pairs of angles that are in the same direction from the points of intersection are called "corresponding angles." Corresponding angles are congruent.
__
In the given diagram, the marked angles are both "southeast" of their respective points of intersection. That means they are corresponding angles, and have the same measure.
(9x -7)° = (7x -3)°
2x = 4 . . . . . . . . . . . divide by °, add 7-7x
x = 2 . . . . . . . . . divide by 2
_____
Check
The measures of the angles are ...
(9(2) -7)° = (18 -7)° = 11°
(7(2) -3)° = (14 -3)° = 11° . . . . same as the first angle, as it should be

how do you factor 3x^2-3x-90
3x^2 - 3x -90
=3 (x^2 - x -30)
=3 (x^2 −6x+5x−30)
=3(x(x−6)+5(x−6))
=3(x−6)(x+5)
People were polled on how many books they read the previous year. Initial survey results indicate that s= 18.1 books. Complete parts (a) through (d) below.
(a) How many subjects are needed to estimate the mean number of books read the previous year within six books with 95%confidence?
This 95% confidence level requires ____subjects. (Round up to the nearest subject.)
(b) How many subjects are needed to estimate the mean number of books read the previous year within three books with 95% confidence?
This 95% confidence level requires _____subjects. (Round up to the nearest subject.)
(c) What effect does doubling the required accuracy have on the sample size?
A.Doubling the required accuracy nearly quadruples the sample size.
B.Doubling the required accuracy nearly halves the sample size.
C.Doubling the required accuracy nearly quarters the sample size.
D. Doubling the required accuracy nearly doubles the sample size.
(d) How many subjects are needed to estimate the mean number of books read the previous year within four books with 99% confidence?
This 99% confidence level requires _____ subjects. (Round up to the nearest subject.)
This 99% confidence level requires ____subjects. (Round up to the nearestsubject.)
Compare this result to part (a). How does increasing the level of confidence in the estimate affect sample size? Why is thisreasonable?
A. Increasing the level of confidence increases the sample size required. For a fixed margin of error, greater confidence can be achieved with a smaller sample size.
B. Increasing the level of confidence decreases the sample size required. For a fixed margin of error, greater confidence can be achieved with a larger sample size.
C. Increasing the level of confidence decreases the sample size required. For a fixed margin of error, greater confidence can be achieved with a smaller sample size.
D. Increasing the level of confidence increases the sample size required. For a fixed margin of error, greater confidence can be achieved with a larger sample size.

Answer:
Flipped over x-axis, Stretched by 4 times in y values, 1 unit to the left, and 8 units down.
Step-by-step explanation:
Sign in front, outside of parentheses, if negative, represents a vertical flip.
Multiple proceeding is the amount of stretch (or compression if it is a value less than 1)
A positive value within the parentheses represents a shift to the left.
The c value of this function being negative shows a downward transition.

What is the length of a diameter of a circle with a radius of 5.7 cm?
Answer:
i believe 27.2 centimeters
Answer:
11.4
Step-by-step explanation:
A radius (labeled r)
[tex]d = r \times 2 \\ = 5.7 \times 2 \\ = 11.4[/tex]
stops at the center so its half the diameter, thus the diameter (labeled d) is:
Four less than the product of a number and 8 is twice the sum of the number and 10 what is the number
Answer:
x=4
Step-by-step explanation:
Four less than the product of a number and 8:
8x−4
is twice the sum of the number and 10, so
8x−4=2(x+10)
Simplify.
8x−4=2x+20
Add 4 to both sides, which is
8x=2x+24
Subtract 2x from both sides:
6x=24
Divide 6 from both sides to isolate the x
x=4
-how I got 20
8x-4=2(x+10) x=8 so 8+10=18 18+2=20
also sorry for posting the answer in the comments and then making an answer after you saw i just wanted da points and hope it helped you :)

Mrs. Thomas is designing a rectangular pool for her backyard. The width of the pool is 7
feet shorter than twice its length. The perimeter of the pool is 75 feet. Write the equation to
represent the length of the pool
(1 Point)
Answer:
For the first one , the answer is 15 , the equation is 75=2f+2(2f-7.5)
For the Callie question , the answer is 20 , the equation is 110=2f+2(2f-5)
The third answer is 23 and the equation is 144=2(2w+3)+2w
Step-by-step explanation:
The length of the pool is 15 feet and the width is 23 feet.
What is the perimeter of the rectangle?The perimeter of a rectangle is defined as the addition of the lengths of the rectangle's four sides.
Let L be the length of the pool.
According to the given information, the width of the pool is (2L - 7) feet.
The perimeter of a rectangle is the sum of all four sides, so we can write the equation:
2L + 2(2L - 7) = 75
Simplifying this equation:
6L - 14 = 75
6L = 89 + 14
L = 89/6
L = 14.833 ≈ 15
So the length of the pool is 15 feet and the width is (2 × 15 - 7) = 23 feet.

90 degree angle is divided into two sides
Answers:
3x + 40 =64
4x - 6 =26
Step-by-step explanation:
So we are dealing with 2 complementary angles with both add up to 90 degrees. We can write an equation that shows this:
(3x+40) + (4x-6) = 90
Combine like terms
7x + 34 =90
Isolate x
7x = 56
x = 8
Now that we found x, all we have to do is substitute it in the equations:
3x + 40 = ?
3(8) +40 = ?
24+40 = ?
64 = ?
4x - 6 = ?
4(8) - 6 = ?
32 - 6 = ?
26 = ?
Answer:
3x+40= 66
4x-6= 26
Step-by-step explanation:
3x+40+4x-6=90˚ (because the square on the angle represents a 90˚)
Add 4x and 3x
Which is 7x
40 minus 6 is 34
The equation now looks like this:
7x+34=90˚
Subtract 34 on both sides:
7x=56
Divide 7 on both sides:
x=8
For 3x+40
Substitute x with 8
the equation now looks like this:
24+40 Which is 66
For 4x-6
4 times 8 is 32
32 minus 6 which is 26
Hope this helps!

A manager at a store is holding a contest where the first, ninth, and ninetieth customers of the day will win a prize. 100 people visit the store that day. Three different friends visit the store that day. What is the probability that they are the first, ninth, and ninetieth customers of the day? Give your answer as a fraction in simplest form.
Answer: 1/970200
Step-by-step explanation:
This is a permutation problem, because the order matters.
There are 100! ways for the 100 customers to visit the store.
There are (100−3)!=97! ways for the three friends to be the first, ninth, and ninetieth customers

Order the side lengths AB, BC, and CA from least to greatest.
(Note that the figure is not drawn to scale.)
Answer:
BC < AC < AB
Step-by-step explanation:
In triangle smallest has the smallest opposite side and so on
first find ∠A = 180 - 59 - 79
= 42
∠A < ∠B < ∠C
Then ∠A opposite side is BC is less
so BC < AC < AB

Answer for brainiest
Answer:
x=72°
Step-by-step explanation:
We know angles around a point equals 360°
Therefore,
(2x-61)°+(x-11)°+3x°=360°
2x-61+x-11+3x=360°
Collect like terms,
2x+x+3x-61-11=360°
6x-72°=360⁰
Evaluate;
6x=360°+72°
6x=432°
Divide both sides by 6
x=72°
A cheerful teen willing to help,
please mark BRAINLIEST,
stay salty...
Answer:
x = 72°
Step-by-step explanation:
there is a total of 360 degrees in a circle
we know we can add the angle measures shown and set it equal to 360
3x + (x-11) + (2x-61) = 360
combine 'like terms':
6x + (-11) + (-61) = 360
6x + (-72) = 360
6x = 432
x = 72
Check:
[2(72)-61] + (72-11) + 3(72) should equal 360
(144-61) + 61 + 216 = 360
83 + 61 + 216 = 360
360 = 360
