Answer:
(2 n)/3-2/3 = n/6+4/3
(2 n)/3-2/3 = (2 n-2)/3:
(2 n-2)/3 = n/6+4/3
Put each term in n/6+4/3 over the common denominator 6: n/6+4/3 = n/6+8/6:
(2 n-2)/3 = n/6+8/6
n/6+8/6 = (n+8)/6:
(2 n-2)/3 = (n+8)/6
Multiply both sides by 6:
(6 (2 n-2))/3 = (6 (n+8))/6
6/3 = (3×2)/3 = 2:
2 (2 n-2) = (6 (n+8))/6
(6 (n+8))/6 = 6/6×(n+8) = n+8:
2 (2 n-2) = n+8
Expand out terms of the left hand side:
4 n-4 = n+8
Subtract n from both sides:
(4 n-n)-4 = (n-n)+8
4 n-n = 3 n:
3 n-4 = (n-n)+8
n-n = 0:
3 n-4 = 8
Add 4 to both sides:
3 n+(4-4) = 8+4
4-4 = 0:
3 n = 8+4
8+4 = 12:
3 n = 12
Divide both sides of 3 n = 12 by 3:
(3 n)/3 = 12/3
3/3 = 1:
n = 12/3
The gcd of 12 and 3 is 3, so 12/3 = (3×4)/(3×1) = 3/3×4 = 4:

a family of five recently replaced its 5-gallon-per-minute showerheads with water-saving 2-gallon per minute showerheads. each member of the family averages 8 minutes in the shower per day. how many gallons will the entire family (5 people) save per day?
The entire family (5 people) save 120 gallons per day.
Subtraction:
Subtraction means we have to find the difference of the numbers.
Given,
A family of five recently replaced its 5-gallon-per-minute showerheads with water-saving 2-gallon per minute showerheads.
Each member of the family averages 8 minutes in the shower per day.
Here we need to find the entire family savings per day.
According to the question,
The total bath time for the whole family is,
=> 8 x 5 = 40
So for one day,
If the showerheads cost 5 gallon per minute, then the cost for the family is,
=> 40 x 5 = 200
If the showerheads cost 2 gallon per minute, then the cost for the family is,
=> 40 x 2 = 80
So, the savings is,
=> 200 - 80
=> 120
So, they save 120 gallons per day.

Step-by-step explanation:
45. find the probability of picking 1 vowel and 4 consonants when 5 letters are picked (without replacement) from a set of alphabet tiles\.\* *you may input your answer as a fraction or rounded to the seventh decimal.
The required probability is 0.45
We have total 26 letters in English, of which 21 are consonants and 5 are vowels.
According to the question, we have to select 5 of them of which 4 will be consonants and 1 will be vowel.
Suppose we want to have the vowel in the first selection, so the probability of picking a vowel is equal to the quotient between the number of vowels and the number of total number of letters.
So the probability is 5/26
Now, a letter has been selected, so in the set, we have 25 letters left.
In the next 4 selections, we must select consonants.
In the second selection the probability is 21/25
In the third selection the probability is 20/24
In the fourth selection the probability is 19/23
In the last selection the probability is 18/22
So, the probability is (5/26)×(21/25)×(20/24)×(19/23)×(18/22)
Now, remember that we take that the vowel must be in the first place, but it can be in any five places, so if we add the permutations of the vowel letter we have,
P = 5×(5/26)×(21/25)×(20/24)×(19/23)×(18/22) = 0.45

Triangle ABC is graphed on a coordinate grid with vertices at A (-2, -4), B (2, -4) and C (0, 2). Triangle ABC is dilated by a scale factor of x with the origin as the center of dilation to create triangle A’B’C with the vertices A’ (-1, -2), B’(1, -2), C’ (0, 1).
Which rule best represents the dilation that was applied to Triangle ABC to create A’B’C’?
(x, y) (2x, 2y)
(x, y) (0.2x, 0.2y)
(x, y) (12x, 12y)
(x, y) (14x, 14y)
Answer:
The rule which best represents the dilation that was applied to Triangle ABC to create A’B’C’ will be:
(x, y) → (1/2x, 1/2y)
Step-by-step explanation:
Given the vertices of a triangle
A(-2, -4)B(2, -4)C(0, 2)After the dilation, the vertices of an image triangle be
A' (-1, -2)B '(1, -2)C' (0, 1)If we closely observe, we can notice that the image triangle vertices A'B'C' are half of the original triangle ABC.
i.e. (x, y) → (1/2x, 1/2y)
verification
A(-2, -4) → A'(-2/2, -4/2) = A'(-1, -2)
B(2, -4) → B'(2/2, -4/2) = B'(1, -2)
C(0, 2) → C'(0/2, 2/2) = C'(0, 1)
Thus, it is verified and we conclude that the rule which best represents the dilation that was applied to Triangle ABC to create A’B’C’ will be:
(x, y) → (1/2x, 1/2y)8x-9+53=180 solve for x
Answer:
x=17
Step-by-step explanation:
1: Simplify both sides of the equation.
8x−9+53=180
8x+−9+53=180
(8x)+(−9+53)=180(Combine Like Terms)
8x+44=180
8x+44=180
2: Subtract 44 from both sides.
8x+44−44=180−44
8x=136
3: Divide both sides by 8.
(8x=136 )/8
x=17

the sum of two numbers is 32 when 5 is subtracted from fourth and one of the number the result is 8 times the other number find the difference between the two numbers
We will need to use the substitution method to solve the question. The difference between the two numbers is 11.5
Substitution method is used to solve a system of equations. First the equation is solved for one variable and then the value is used in the other equation to solve for the other unknown variable. In this question we have been told the sum of two numbers is 32. Let us take the two numbers as x and y. Then we can say that
x+y=32 ...(i)
Next we know that when 5 is subtracted from 4 times one number the result is 8 times the other number, we can write it as
4x-5=8y
4x-8y=5....(ii)
So we have two equations
x+y=32
4x-8y=5
We will multiply equation (i) by 4 to cancel out x and solve for y
4x+4y=128
4x-8y=5
(-) (+) (-)
-----------------
12y=123
y=10.25
We substitute the value of y in equation (i)
x+y=32
x+10.25=32
x=32-10.25=21.75
We need to find the difference between two number which is x-y=21.75-10.25=11.5
Therefore we found out by substitution method that the difference between the two numbers is 11.5
