how do I solve for 3(2x-1)+2x=4x-11
Answers
Answer:
x=-2
Step-by-step explanation:
3(2x-1)+2x=4x-11
6x-3+2x=4x-11
8x-3=4x-11
8x=4x-8
4x=-8
x=-2
The answer to the equation is \(x=-2\)
First, you must use distributive property to simplify the equation.
\(6x-3+2x=4x-11\)
Then, you must combine like terms.
\((6x+2x)-3=4x-11\)
\(8x-3=4x=11\)
Next, you must subtract 4x on each side
\(4x-3=-11\)
Then, add 3 on both sides
\(4x=-8\)
Finally, divide both sides by 4
\(\frac{4x}{4} =\frac{-8}{4}\)
\(x=-2\)

240 inches per hour
Step-by-step explanation:
If he travels 10 feet (120 inches) in 30 minutes then you need to multiply both of those numbers by 2 to get 20 feet (240 inches) and 60 minutes (1 hour)
Answer:
240
Step-by-step explanation:
10 feet is 120 inches, because each foot has 12 inches in it.
There are (2) 30 minutes in an hour--or and hour is (2)(30 minutes).
The 120 inches traveled in 30 minutes are multiplied by 2 to get 240 inches per hour.

In 2007 Toyota sold 81 thousand more Camrys in the US than Honda sold Accords. If the two cars accounted for 865 thousand cars sold, how many of each were sold?
Please show steps!!
Answers
Answer:
Step-by-step explanation:
Toyota = Honda + 81000 Honda needs 81000 more vehicles to catch Toyota
Toyota + Honda = 865000
Put Toyota from the first equation, into the second equation.
Honda + 81000 + honda = 865000 Subtract 81000 from both sides
-81000 -81000
Honda + Honda = 784000 Combine
2 Honda = 784000 Divide both sides by 2
/2 /2
Honda = 392000
Honda + Toyota = 865000
392000 + Toyota = 865000 Subtract 392000 each side
-392000 = -392000
Toyota = 473000

for what values of a are the following expressions true?
|a+5|=a+5
|a+5|=-5-a
Answers
The expression |a+5|=a+5 is true for any value of a greater than or equal to -5, and |a+5|=-5-a is true for any value of a less than or equal to -5.
For the first expression, |a+5|=a+5, this is true when a is equal to or greater than -5. To prove this mathematically, we can use the absolute value definition. The definition states that the absolute value of any real number a is equal to the distance of a from 0 on the number line. This can be expressed as |a| = a if a is greater than or equal to 0, and |a| = -a if a is less than 0. Using this definition, we can represent the first expression as |a+5| = a + 5. If we substitute the absolute value definition for |a+5|, we get a + 5 = a + 5, which is true for any value of a greater than or equal to -5.
For the second expression, |a+5|=-5-a, this is true when a is equal to or less than -5. To prove this mathematically, we can again use the absolute value definition. Representing as |a+5| = -5 - a, substituting the absolute value definition yields -a = -5 -a. This is true for any value of a less than or equal to -5.

Answers
Answer:
2) 25.48
The diameter of the circle d = 25.48
Step-by-step explanation:
Step(i):-
we know that the diameter of a circle d = 2 r
The circumference of the circle = 2π r
Given that the circumference of the circle = 80 feet
Step(ii):-
The circumference of the circle = 2π r = 80
⇒ π (2r )= 80
⇒ πd = 80
⇒ \(d = \frac{80}{3.14}\)
d = 25.477
Final answer:-
The diameter of the circle d = 25.477

Find the solution set for |3q-2|=7 .
Answers
Here is the website for your answer

When we have an absolute value it means the value could be positive or negative; therefore, we must test both possibilities, and get two answers.
Here we will check what q would be if the absolute value is negative
- (3q-2) = 7
-3q = 5
-q = 5/3
q = - (5/3)
And now we will check what q would be if the absolute value is positive
(3q -2) = 7
3q = 9
q = 3

The area of a rectangle is 80 square units. A side of the rectangle, representing the
length, is 4 units long. Which could be the vertices of aside of the rectangle that
represents the width?
Answers
Answer:
So the width of the rectangle is 20 units.
Step-by-step explanation:
Since the area of the rectangle is 80 square units and the length of one side is 4 units, we can use the formula for the area of a rectangle (A = lw) to find the width of the rectangle. We can set up the equation like this:
A = lw
80 = 4w
w = 20
So the width of the rectangle is 20 units. This means that the vertices of one of the sides of the rectangle that represents the width could be (0,0), (0,20), (20,0), and (20,20). These coordinates assume that the lower left corner of the rectangle is at the origin (0,0). If the rectangle is not at the origin, the coordinates of the vertices would be different. For example, if the lower left corner of the rectangle was at (-5,5), the coordinates of the vertices would be (-5,5), (-5,25), (15,5), and (15,25).
Patty has $10 000 that she would like to invest. She has found an investment that will pay 5.6% compounded monthly.a)Use the Rule of 72 to estimate the length of time it will take for her investment to double.b)Use the TVM solver to find the exact amount of time it will take for her investment to double.
Answers
a)
The Rule of 72 states that the time required to double the investment (in years) is given by the formula below:
\(\text{time to double}=\frac{72}{r}\)Where r is the investment rate in percentage.
So, for r = 5.6, we have:
\(\text{time to double}=\frac{72}{5.6}=12.86\text{ years}\)Therefore the time needed to double is 12.86 years.
b)
In order to calculate the exact time to double, let's use the formula below:
\(A=P(1+\frac{r}{n})^{nt}\)Where A is the final amount after t years, P is the principal (initial amount), r is the interest rate and n is how many times the interest is compounded in a year.
So, for A = 2P, r = 0.056 and n = 12, we have:
\(\begin{gathered} 2P=P(1+\frac{0.056}{12})^{12t} \\ 2=(1+0.0046667)^{12t} \\ 2=1.0046667^{12t} \\ \ln (2)=\ln (1.0046667^{12t})^{} \\ \ln (2)=12t\cdot\ln (1.0046667) \\ 12t=\frac{\ln (2)}{\ln (1.0046667)} \\ 12t=\frac{0.693147}{0.0046558} \\ 12t=148.878 \\ t=12.4 \end{gathered}\)Therefore the time needed to double is 12.4 years.

A z-score less than -2 or greater than 2 is considered unusual in a normal curve. Assuming that the data collected form normal distributions, what would data that is outside the [-2,2] range mean?
Answers
The data points from the set of collected that are outside the [-2, 2] range means that the data is an outlier or unusual data
What is a z–score?The z–score also known as standard score is the number of standard deviation a score is differs from the mean or average score
The z–score is given by the formula;
\(Z = \frac{x - \mu}{ \sigma} \)
The Z–Score is therefore, the number of standard deviations, a data point, x is far from the mean, \( \mu \)
The standard deviation, \( \sigma \), is given by the formula;
\( \sigma = \sqrt{ \frac{ \sum {( x_{i} - \mu)}^{2} }{N} } \)
As the value of \( \sigma \) increases, the variability increases, and the Z–Score decreases, such that a Z–Score of less than -2 or greater than 2 are unusual.
From the z–score calculator, the probability that a data point has a z–score of less than -2 or more than 2 is 0.02275
Such a data point can be taken as an outlier
Therefore, data that is outside the [-2, 2] range is an unusual (outlier) data
