Add n on both sides:
3m = km - 8 + n
Subtract km on both sides:
3m - km = n - 8
Factor the Left-Hand Side:
m(3 - k) = n - 8
Divide both sides by (3 - k):
m = (n - 8) / (3 - k)
Answer:
(8-n)/(k-3) =m
Step-by-step explanation:
3m-n=km-8
Subtract 3m from each side
3m -3m-n=km -3m-8
-n =km -3m-8
Add 8 to each side
8-n =km -3m-8+8
8-n =km -3m
Factor out m
8-n =m(k -3)
Divide by (k-3)
(8-n)/(k-3) =m(k -3)/( k-3)
(8-n)/(k-3) =m
A news offers a subscription that costs $28.50 for 6 months. what is the unit price per month? Show your work. -Ratio
Answer: $4.75.
Step-by-step explanation:
It is given that a news offers a subscription that costs $28.50 for 6 months.
We need to find the unit price per month.
The formula for unit price per month is
[tex]\text{Unit price per month}=\dfrac{\text{Total subscription cost}}{\text{Number of months}}[/tex]
[tex]\text{Unit price per month}=\dfrac{28.50}{6}[/tex]
[tex]\text{Unit price per month}=\dfrac{285}{60}[/tex]
[tex]\text{Unit price per month}=4.75[/tex]
Therefore, the unit price per month is $4.75.

How do I solve this?
Answer:
x is in the range [-1,4]
Step-by-step explanation:
I haven't worked with absolute value inequalities in awhile, but let's take a wack at this.
We are given the following inequality:
| 2x - 3 | <= 5
This implies two possible cases:
[1] -5 <= 2x -3
Or
[2] 2x - 3 <= 5
So let's solve x for both of these cases:
[1] -5 <= 2x - 3
-2 <= 2x
-1 <= x
[2] 2x - 3 <= 5
2x <= 8
x <= 4
So from these cases, we can say the following is true:
x >= -1 and x <= 4
Thus, we can write this in the form
-1 <= x <= 4
Or in interval notation:
{ x is element of reals | -1 <= x <= 4}
Also written as
x is in the range [-1,4]
Where the closed brackets represent 1 and 4 as possible answers whereas parenthesis would imply they were not.

find the slope of the line that passes through (3,4) and (1,7)
Answer:
-3/2
Step-by-step explanation:
Since we have two points, we can use the slope formula
m = ( y2-y1)/(x2-x1)
= ( 7-4)/(1-3)
= 3/-2
= -3/2
Answer:
The answer is
[tex] - \frac{3}{2} [/tex]Step-by-step explanation:
The slope of a line given two points can be found by using the formula
[tex]m = \frac{y_{2} -y_{1}}{x_{2} -x_{1} } [/tex]
where
(x1 , y1) and (x2 , y2) are the points
m is the slope
From the question the points are
(3,4) and (1,7)
The slope is
[tex]m = \frac{7-4}{1 - 3} \\ = - \frac{3}{2} [/tex]
We have the final answer as
[tex] - \frac{3}{2} [/tex]

The numbers on two consecutively numbered time lockers have a sum of 129. What are the locker numbers? The locker numbers are?
x = one number
x + 1 = second number
x + x + 1 = 129
Combine like terms
2x + 1 = 129
Subtract 1 from both sides.
2x = 128
Divide both sides by 2
x = 64
The locker numbers are 64 and 65

what number is 7 hundredths greater than 5.25
Answer:
36,750.
Step-by-step explanation:
The way to determine the number that is seven hundred times greater than 5.25 is by multiplying those numbers, the result being the number in question.
Thus, the following multiplication must be performed:
700 x 5.25 = X
3,675 = X
Thus, the number that is seven hundred times greater than 5.25 is 3,675.
The population of mosquitoes in a certain area increases at a rate proportional to the current population, and in the absence of other factors, the population doubles each week. There are 400,000 mosquitoes in the area initially, and predators (birds, bats, and so forth) eat 40,000 mosquitoes/day. Determine the population of mosquitoes in the area at any time. (Note that the variable t represents days.) Enter an exact answer.
Answer:
[tex]P=400000(2^t)-40000t[/tex]
Step-by-step explanation:
The initial number of mosquitoes is 400000, and they double each day. This represents an exponential growth equation. If t represent days and P represent the population of the mosquitoes, hence this can be represented by the equation:
[tex]P=400000(2^t)[/tex]
Also, the predators eat the mosquitoes at a rate of 40,000 mosquitoes/day. This means that each day, the mosquitoes reduce by 40000t, therefore this can be represented by:
[tex]P=400000(2^t)-40000t[/tex]

When Emily woke up, the temperature was 8°F. By noon, the temperature had risen by 3°F. It rose another 6°F in the afternoon to reach the day’s high temperature. By the time Emily went to bed, the temperature had dropped 21°F from the high temperature. What was the temperature when Emily went to bed?
Answer:
The temperature when Emily went to bed was -4°F.
Step-by-step explanation:
8°F + 3°F = 11°F (noon)
The temperature had risen by 3°F by noon. This means to add 3.
noon + 6°F = the day's high temperature
11°F + 6°F = 17°F (the day's high temperature)
The temperature rose another 6°F in the afternoon. This means add 6 to the temperature from noon.
high temperature - 21°F = temperature at bed
17°F - 21°F = -4°F
The temperature dropped by 21°F when Emily went to bed. This means to subtract 21 from the day's high temperature.
Risen, rose, and increase mean addition.
Decrease, dropped, and decline mean subtraction.

Find the constant of variation for the relation and use it to write an equation for the statement. Then solve the equation. If y varies inversely as the square of x, and y=7/4 when x=1, find y when x=3
Answer:
y=7/36
Step-by-step explanation:
Since y varies inversely to the square of x, we can say
[tex]y = z/x^2[/tex]
where z is the constant of variation.
Then, from knowing that y=7/4 when x=1, we plug them in to find z.
[tex]7/4=z/(1^2)\\z=7/4[/tex]
Now we have the full equation,
[tex]y=7/4x^2[/tex]
Plug x=3 in and we get,
[tex]y=7/4(3^2) = 7/36[/tex]

We defined the operation of concatenation for sets of strings on p. 10, AB = { XY | X ∈ A and y ∈ B}Are the regular sets closed under concatenation? That is, if A and B are regular sets, is AB guaranteed to be a regular set? Prove or show a counterexample.
Answer and Explanation:
Solution: The operation of concatenation for a set of string on p. and the set is
AB = {XY | X ∈ A and y ∈ B}.
We need to satisfy all these following properties to find out the standard set is closed under concatenation.
1- Union of two standard sets also belongs to the classic collection. For example, A and B are regular. AUB also belongs to a regular group.
2- Compliment of two standards set A and B are A’ and B’ also belonging to the standard set.
3- Intersection of two standards set A and B is A∩B is also a regular set member.
4- The difference between two regular sets is also standard. For example, the difference between A and B is A-B is also a standard set.
The closure of the regular set is also standard, and the concatenation of traditional sets is regular.

Step-by-step explanation:
When I double my number, add four, and then subtract my number and subtract three, I get my number plus one. What is my number?
Answer: Let your no.= x
double the number=2x
add 4 = 2x+4
subtract same number=2x+4-x
subtract 3=2x+4-x-3
I get my number plus 1=x+1
so equation we get
2x+4-x-3=x+1
x+1=x+1
x=x
it means x is equal to all real number
So your number can be any real number
