6 - 4x = 6x - 8x + 2
6 - 4x = ___ + 2
6 = ___ + 2
___ = ___
___ = x
Answer:
6 − 4 x = 6 x − 8 x − 2 Since x
is on the right side of the equation, switch the sides so it is on the left side of the equation.
6 x − 8 x − 2 = 6− 4 x Subtract 8 x from 6 x . − 2 x − 2 = 6 − 4 x
Move all terms containing x
to the left side of the equation.
Tap for fewer steps...
Add 4 x
to both sides of the equation.
− 2 x − 2 + 4 x = 6 Add − 2 x and 4 x . 2 x − 2 = 6
Move all terms not containing
x to the right side of the equation.
Tap for fewer steps...
Add 2
to both sides of the equation.
2 x = 6 + 2 Add 6 and 2 . 2 x = 8
Divide each term by
2 and simplify.
Tap for fewer steps...
Divide each term in
2 x = 8 by 2 . 2 x 2 = 8 2 Cancel the common factor of
2 . Tap for more steps...
x = 8 2 Divide 8 by 2 .

9) It takes 7 minutes for Isabella to walk
around the gym track twice. At this
rate, how many times can she walk
around the track in a half hour?
Answer:
8 4/7
Step-by-step explanation:
Use a proportion.
Let the unknown number of laps for 30 minutes be x.
7 minutes is to 2 laps as 30 minutes is to x laps
7/2 = 30/x
Cross multiply.
7x = 2 * 30
7x = 60
x = 60/7
x = 8 4/7
Answer: 8 4/7
Isabella walks twice around the gym track in 7 minutes. She can do 60/7 laps of the track in a half hour if she continues moving at this pace.
What is the meaning of the term “laps”?
Running a lap is equivalent to making a full circle of a track during a race or while exercising while walking. the front portion of the human body, when seated, from the waist to the knees. the area of clothing that, while a person is sitting, covers the front of their body from the waist to their knees. a location, setting, or circumstance that promotes rest or nurturing: the lap of luxury.
Laps are being done to get a good workout. For beginners, 20–30 laps in 30 minutes is frequently an effective and reachable target. If you're more advanced, try to do 40 to 50 laps in the same amount of time, and aim for 60 or more.
Let x equal the undetermined number of laps for 30 minutes.
7 minutes equals 2 laps, while 30 minutes equals x laps.
[tex]\frac{7}{2} = \frac{30}{x}[/tex]
Cross multiply.
[tex]7x = 2 \times 30\\7x = 60\\x = \frac{60}{7}\\[/tex]
Therefore, Isabella can do 60/7 laps of the track in a half hour if she continues moving at this pace.

Analyze tables use the table that shows the percents of blood types of 145 donors during a recent blood drive
a. find how many donors had type b blood. Round to the nearest whole number if necessary ____
b. How many donors did not have type O blood? Round to the nearest whole number if necessary ____
c. Which blood type has less than 10 donors?
blood type percent
O 45
A 40
B 11
AB. 4
Answer:
a. 16
b. 80
c. Blood type AB
Step-by-step explanation:
Given:
O = 45%
A = 40%
B = 11%
AB = 4%
Total number of donors = 145
a. No. of donors that had type B blood = [tex] \frac{11}{100}*145 = \frac{1,595}{100} = 15.95 [/tex]
Type B blood donors ≈ 16
b. No. of blood donors without blood type O = [tex] \frac{40 + 11 + 4}{100}*145 = \frac{55}{100}*145 = \frac{7,975}{100} = 79.75 [/tex]
Those without blood type O ≈ 80
c. Find the number of people that had type AB:
Type AB = [tex] \frac{4}{100}*145 = 5.8 [/tex] ≈ 6. This is less than 10 donors.
Therefore, blood type AB had less than 10 donors.

A penguin walks 10 feet in 6 seconds. At this speed:
How far does the penguin walk in 45 seconds?
How long does it take the penguin to walk 45 feet?
Explain or show your reasoning.
75 feet the penguin walk in 45 seconds and in 27 seconds the penguin walk 45 feet.
What is Ratio?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.
Given,
penguin walks 10 feet in 6 seconds
At the same rate we need to find the distance walked by penguin in 45 seconds
Let x be the distance travelled by penguin in 45 seconds
10/6=x/45
Apply cross multiplication
45(10)=6x
450=6x
Divide both sides by 6
x=75
So 75 feet the penguin walk in 45 seconds.
Now let us find how long it takes for penguin to walk 45 feet.
Let x be the time
10/6=45/x
Apply cross multiplication
10x=270
Divide both sides by 10
x=27
In 27 seconds the penguin walk 45 feet.
Hence, 75 feet the penguin walk in 45 seconds and in 27 seconds the penguin walk 45 feet.

if ta=16 & mh= 18 what is the lenth of mr?
Answer:
the length of MR = 9
Step-by-step explanation:
Looking at the figure, we can tell that segment TR is congruent to segment RA, meaning TR has equal length to RA and the same goes to MR and RH. Since the problem gives us the total length of line TA and line MH, we can say that the length of MR is half of the total length of MH. Therefore, length of MR is 9.

Answer:
1. a)x² + y² = 29 ------------------(1)
y² - x² = 23 ----------------(2)
y² = 23 + x²
Using the value of y² in the first equation:
x² + y² = 29
x² + (23 + x²) = 29
2x² = 6
x² = 3
x = √3
Using the value of x in equation (2)
y² - x² = 23
y² - 3 = 23
y² = 26
y = √26 and x = √3
b) ( 1 - 12x) / 3 < 0 = 1-12x < 0 = x > 1 / 12
(1-x) / 2 ≤ (3-x) 3 = 3 - 3x ≤ 6 - 2x = -3 ≤ x
In these 2 equations, the value of x will be the values of x common to both the inequalities
Since the second equation starts at a much lower value than the first equation, and they are both going up, all the values for the first equation will also stand for the second equation
Hence, the value of x for the given system of equations is
x > 1/12

We are given that Sin α = (2√3) / 3 or 2/√3
According to the pythagorean law:
sin²α + cos²α = 1
4 / 3 + cos²α = 1
cos²α = (3-4)/3
cos²α = -1/3
cos α = √(-1/3) or i / √3 since √-1 is also known as i
Cosec α = 1/ Sin α
Cosec α = 1 / (2/√3)
Cosec α = √3 / 2
Sec α = 1 / cos α
Sec α = 1 / √(-1/3)
Sec α = (√3) / (√-1)
Since (√-1) is also known as i , we can write this as:
Sec α = (√3) / i
Tan α = Sin α / Cos α
Tan α = (2√3 / 3) / (i / √3)
Tan α = (2√3 * √3) / 3 * i)
Tan α = 2 / i
Cot α = 1/Tan α
Cot α = 1 / (2 / i)
Cot α = i / 2

Andre says that any real number can go in either of the boxes and A will be a
polynomial. Is he correct? Explain your reasoning.
Answer:
Andy is incorrect
Step-by-step explanation:
[See attachment for complete question]
Andy is incorrect because of the following.
Filling the empty boxes with any real numbers does not guarantee that the expression will be a polynomial.
For instance, if the expression is completed as thus:
(5x⁴ + 4x³)(4x^(2.7981) - 6) = A
This expression is not a polynomial because all powers of x must be non negative and it must be an integer.
So, Andy's statement is incorrect
