Answer:
-4=x
Step-by-step explanation:
Okay, let's do this step-by-step for the best results!
We need to make sure that common variables can be put together first. If you did not know this, look at PEMDAS.
-x+7=-6x-13
We need to add -x and -6x together. If we do that then you would get,
7=-5x-13
Let's add 13 to 7 now.
20=-5x
Lets divide -5 with 20.
-4=x
I hope this helped!
Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{x = - 4}}}}}[/tex]
Step-by-step explanation:
[tex] \sf{ - x + 7 = - 6x - 13}[/tex]
Move 6x to left hand side and change it's sign
[tex] \dashrightarrow{ \sf{ - x + 6x + 7 = - 13}}[/tex]
Move 7 to right hand side and change it's sign
[tex] \dashrightarrow{ \sf{ - x + 6x = - 13 - 7}}[/tex]
Collect like terms
[tex] \dashrightarrow{ \sf{ 5x = - 13 - 7}}[/tex]
Calculate
[tex] \dashrightarrow{ \sf{5x = - 20}}[/tex]
Divide both sides by 5
[tex] \dashrightarrow{ \sf{ \frac{5x}{5} = \frac{ - 20}{5} }}[/tex]
Calculate
[tex] \dashrightarrow{ \sf{x = - 4}}[/tex]

The US courts are reviewing a case to see whether a work has been refused fairly. What is an example of something they might consider when trying to decide whether the use was fair?
Answer:
The Purpose and Character of the usage of the work.
Step-by-step explanation:
In the United States of America, there is a terminology used in court called Fair use. This is a law in the USA that permits a limited use of one or more copyrighted materials without the need to first acquire permission from the holder of the copyright.
Thus, an example of something they might consider when trying to decide whether the use was fair is:
The Purpose and Character of the usage of the work.
This is because the original purpose of the work may have been altered to mean something new or different or it was just copied exactly into another work.
So knowing the purpose and character of usage of the work or material in question would be something they would consider
A pyramid has a square base with an area of 169ft. What is the perimeter of the base of the pyramid?
Answer:52 ft.
Step-by-step explanation: If the area of the base of the pyramid is
169
ft
2
then each side of the base is
13
ft
long because the base of the pyramid is a square.
Length of the side,
s
=
√
169
=
13
Iif we take the area of a square
A
=
s
2
where
s
=
13
we get the area of the base to be
169
ft
2
thus proving that each side of the base is
13
ft
long.
So to find the perimeter of the base of the pyramid we use the formula:
P
=
4
s
where
s
=
13
ft
and thus,
p
=
4
⋅

=

Is 7.787887888… a rational number? PLEASE ANSWER ASAP!! WILL GIVE BRAINLIEST!!!!!
Answer:
yes it is a rational number because the number has a repeating pattern
Step-by-step explanation:
The number 7.787887888... is rational, Yes; it has a pattern that is repeating.
What is an irrational number?It is defined as the numbers in all real numbers which cannot be represented as rational numbers, in other words, the irrational number cannot be expressed in the form of p/q form.
A rational number is a sort of real number that has the form p/q and does not equal zero.
It is given that:
The number is 7.787887888
As we know,
The rational number can be represented in the form of p/q where q cannot be equal to zero.
If the number is terminated after some decimal places then it is said to be a rational number.
If the number is repeating its digit after decimal then it is said to be an irrational number.
Thus, the number 7.787887888... is rational, Yes; it has a pattern that is repeating.

The population of a colony of bacteria can be modeled by the function P(t) = 19,300(5)^t, where t is the elapsed time
in hours. What is the inverse function?
Answer:
C. P–1(t) = log5 (StartFraction t Over 19,300 EndFraction)
Step-by-step explanation:
The inverse function of P(t) is [tex]P^{-1} (t)=log_{5}( \frac{t}{19300})[/tex]
What is an inverse function?The inverse function is a function obtained by reversing the given function. An inverse is a function that serves to “undo” another function. The domain of the original function becomes the range of inverse function and the range of the given function becomes the domain of the inverse function.
For the given situation,
The function P(t) = 19,300(5)^t, where t is the elapsed time in hours.
Steps to find inverse function:
Step 1: Replace P(t) as y
[tex]P(t) = 19,300(5)^t[/tex]
⇒ [tex]y= 19,300(5)^{t}[/tex]
Step 2: interchange t and y
⇒ [tex]t = 19,300(5)^y[/tex]
Step 3: Now solve for y
⇒ [tex]\frac{t}{19300} =5^y[/tex]
By law of logarithm,
[tex]a^{x} = y[/tex]
⇒ [tex]log_{a} y=x[/tex]
Thus the equation becomes,
⇒ [tex]log_{5} \frac{t}{19300}=y[/tex]
Step 4: Now replace y as [tex]P^{-1}( t)[/tex]
⇒ [tex]P^{-1} (t)=log_{5}( \frac{t}{19300})[/tex]
Hence we can conclude that the inverse function of P(t) is [tex]P^{-1} (t)=log_{5}( \frac{t}{19300})[/tex].

Answer:
2 (5 x - 2) = 10 x - 4 or x = 2/5 (if you need to solve for x)
Step-by-step explanation:
Simplify the following:
4 x - 2 + 6 x - 2
Hint: | Group like terms in 4 x - 2 + 6 x - 2.
Grouping like terms, 4 x - 2 + 6 x - 2 = (4 x + 6 x) + (-2 - 2):
(4 x + 6 x) + (-2 - 2)
Hint: | Add like terms in 4 x + 6 x.
4 x + 6 x = 10 x:
10 x + (-2 - 2)
Hint: | Group the negative terms in -2 - 2 together and factor out the minus sign.
-2 - 2 = -(2 + 2):
10 x + -(2 + 2)
Hint: | Evaluate 2 + 2.
2 + 2 = 4:
10 x - 4
Hint: | Factor out the greatest common divisor of the coefficients of 10 x - 4.
Factor 2 out of 10 x - 4:
Answer: 2 (5 x - 2)
________________________________
if you need to solve for x then:
Solve for x:
10 x - 4 = 0
Add 4 to both sides:
10 x + (4 - 4) = 4
4 - 4 = 0:
10 x = 4
Divide both sides of 10 x = 4 by 10:
(10 x)/10 = 4/10
10/10 = 1:
x = 4/10
The gcd of 4 and 10 is 2, so 4/10 = (2×2)/(2×5) = 2/2×2/5 = 2/5:
Answer: x = 2/5

chosen at random, the probability of getting a gumdrop is, and the probability
of getting a jellybean is 3. What is the probability of getting a jawbreaker?
Answer:
1/2
Step-by-step explanation:
First, I added the two numbers tat we had already.
1/6+1/3=1/6+2/6=3/6=1/2
Then, I subtracted the sum (1/2) from the total (1).
1-1/2=1/2

hanks pickup can travel 68 miles on 4 gallons of gas. How many gallons will hanks pickup need to travel 34 miles?
Answer: This is a ratio of miles (m) per gallon (g), which can be written as the fraction m/g. So Hank's truck can do 68 miles per 4 gallons, or 68/4. The other ration of miles per gallon is 34 miles to (x) amount of gallons. If you set these ratios equal to each other, the resulting equation can help you solve for the number of gallons.

On the number line, the number 14 will appear on the right side of -23 with respect to zero from front.
What is a number line?Integers are arranged at equal intervals along horizontal straight lines called number lines. A number line can be used to represent every number in a series.
Number line is a graphical representation of whole numbers, natural numbers, rational and irrational numbers. which represents both negative and positive numbers such that, positive numbers from 1 to infinity lie on the right-hand side of zero and negative numbers from (- 1) to (- infinity) lie on the left-hand side of zero.
Therefore, zero is considered as the reference point.
Number 14 is positive natural number, it appears on the right side of zero and (-23) appears on the left side of zero.

Answer:
a) [tex]y=1[/tex]
b) [tex]x=-3[/tex]
Step-by-step explanation:
Recall the forms of vertical and horizontal lines
Horizontal lines come in the form of [tex]y=0x+b[/tex], so the slope of the equation is zero. The value of b will be the y-value of the point that you're given.
This means that the equation for a would be y=1
Vertical lines come in the form of [tex]x=a[/tex]. For this line, the value of a would be equivalent to the x-value of the given point. Therefore, b. would be [tex]x=-3[/tex]

The measure of an angle is 103°. What is the measure of its supplementary angle?
Answer:
77
Step-by-step explanation:
Let's let the unknown number be x.
Supplementary angles add up to a total of 180 degrees. Since we already know one angle is 103, this means that:
[tex]103+x=180[/tex]
Subtract 103 from both sides:
[tex]x=77\textdegree[/tex]
So, the measure of its supplementary angle is 77 degrees.

For an apartment complex, the association collects $158,000 from all of its 211 residents. What is the average rent per capita for this apartment complex?
Answer:
$748.42
Step-by-step explanation:
The average rent per capita is used to measure the average rent paid by a group of people in an apartment or an area. The rent per capita estimates the average rent charged for each resident. It is ratio of the total rent paid by the people in the area to the number of residents. Hence:
The average rent per capita = Total rent / number of residents = $158000 / 211 residents = $748.42
