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

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:

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

four consecutive integers sum to 22 what is the least of these integers
Answer:
4
Step-by-step explanation:
To get 22 with four consecutive integers, we need the integers 4, 5, 6, and 7.
(4 and 5 equal 9, then 9 and 6 equal 15, and 15 and 7 equal 22.)
4 is the smallest of these four, and thus the least of these.
What is the distance from

if an is a monotone sequence and if an has a convergent subsquence then an converges to the same limit
limₐ→∞xₙₐ= limₙ→∞xₙ= L;
Let xₙ be a monotonically increasing sequence. Thus:
xₙ₊₁≥xₙ
Consider a subsequence of xₙ namely xₙₐ. Then:
xₙₐ≥xₙ, ∀nₐ≥n
We are also given that:
limₐ→∞xₙₐ=L
Given that fact we know that xₙₐ is bounded above. Therefore:
xₙ≤xₙₐ≤L
Now by monotone convergence theorem a monotone bounded sequence must be convergent. Also by uniqueness of a limit for a convergent sequence and the fact that all its subsequences are also convergent to the same limit:
limₐ→∞xₙₐ= limₙ→∞xₙ= L

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

Mrs smith invested r60 000 at a bank for two years with compound interest.in the first year she received an interest rate of 4,3% per annum while in the second year the interest rate was 5,1 per annum mrs smith stated that she would have enough money at the end of second year to pay the residual value of the ford figo show all calculations whether het statement is correct
By using the formula of compound interest we can say that at the end of second year Mrs. Smith will have $65,771.58.
What is Compound Interest?The interest earned from the initial deposit plus the cumulative interest is known as compound interest.
A = P(1 + r/n)^(nt), where P is the principle balance, r is the interest rate, n is the number of times interest is compounded per time period, and t is the total number of time periods, is the formula for compound interest.
Given that,
For first year,
P (principal) = $60,000.00
R = 4.3%
n = 1
t = 1
First, convert R as a percent to r as a decimal
r = R/100
r = 4.3/100
r = 0.043 rate per year,
Then solve the equation for A
A = P(1 + r/n)^nt
A = 60,000.00(1 + 0.043/1)^(1×1)
A = 60,000.00(1 + 0.043)^(1)
A = $62,580.00
A = P + I where,
P (principal) = $60,000.00
I (interest) = $2,580.00
So, by the end of second year Mrs. Smith will have $62,580.00.
Now, the amount calculated from first year will become the principle for second year.
For second year,
P (principal) = $62,580.00
R = 5.1%
n=1
t=1
First, convert R as a percent to r as a decimal
r = R/100
r = 5.1/100
r = 0.051 rate per year,
Then solve the equation for A
A = P(1 + r/n)^nt
A = 62,580.00(1 + 0.051/1)^(1×1)
A = 62,580.00(1 + 0.051)^(1)
A = $65,771.58
A = P + I where,
P (principal) = $62,580.00
I (interest) = $3,191.58
So, by the end of second year Mrs. Smith will have $65,771.58.

Barinda is considering running for student government. However, she knows she will have to work about 10 hours fewer per week if elected, and she makes $ 7 an hour. The campaign will also cost her about $100 in campaign buttons and posters. What is her opportunity cost for serving on student government if elected if she actively serves for 30 weeks?
Answer: $2,200
Step-by-step explanation:
The opportunity cost is the sum of the amount she spent on the election and the amount she would lose in total from serving on the student government.
Amount she would lose in wages
= 7 * 10 hours * 30 weeks
= $2,100
Opportunity cost = 2,100 + 100
= $2,200
