find the first term and the common difference of an arithmetic progression in which t5=3x-y and t11=5y
t5 refers to term 5 and t11 refers to term 11
first term: 5x-5y
common difference: -x/2 + y
The common difference is d = -0.5x + y and the first term is 5x-5y
Geometric progressionThe nth term of the geometric progression is expressed as:
[tex]T_n=a+(n-1)d[/tex]
where;
a is the first termr is the common ration is the number of termsThe fifth term of the sequence is expressed as:
[tex]T_5=a+4d=3x-y[/tex]
[tex]T_{11}=a+10d=3x-y[/tex]
Take the difference of the terms:
[tex]4d-10d=3x-y-5y\\-6d=3x-6y\\d= -0.5x+y[/tex]
Get the first term:
a = 3x - y - 4(-0.5x+y)
a = 3x - y + 2x - 4y
a = 5x - 5y
Hence the common difference is d = -0.5x + y and the first term is 5x-5y

x =
Answer:
x = 8, y = 8
Step-by-step explanation:
So we know angle CAB is congruent to angle ACB so both angles are 69.
Now we add 69+69 and we get 138. Subtract from 180.
180 - 138 = 42.
Now, we set up the equation to 5x+2=42,
subtract two from both sides and get 5x = 40,
divide both sides by 5 and you get x=8.
You can simply plug in x to 5 and add two and still get 42.

Answer:
26 or 27 minutes (read the last part of the explanation)
Step-by-step explanation:
So there are 3 minutes Jane already has for $0.75. She has $3.60, so first just subtract the 75 cents from the total amount of money, to get $2.85. Each minute after costs $0.12 so just divide the 2 numbers. You should get 23.75, that's the number of minutes. Add the 3 minutes back on to get the total time and you get 26.75, it says round to the nearest whole number, which would be 27, but since that would cost more money than Jane actually has, I think it would be 26 minutes

For literal equations you do not necessarily need a numerical answer. You just need to get the variable you are supposed to solve for on one side of the equation by itself. To do this you will follow the same steps you do when you normally solve for x (or any other variable)

#11. y=7m+6
First subtract 6 over to the other side
y-6=7m
then divide the 7 over
(y-6)/7=m
m=(y-6)/7
#13 A=(Z+7)3
Divide the three over to the other side of the equation
A/3=Z+7
Now the 7 is free to be subtracted from both sides
(A/3)-7=Z
#17. (2x/5)-9=6
First add 9 to both sides
2x/5=6+9
2x/5=15
Multiply both sides of the equation by 5
2x=5(15)
2x=75
Divide by 2
x=75/2
x=37.5

Answer:
You need help with both or can I just help with one ?
Step-by-step explanation:
Answer:
14,275
1013
Step-by-step explanation:
1: To get the population in the year 2001 we would have to multiply 4500 by 1.08. To get the population in 2002 we would have to multiply: 4500(1.08)(1.08) or 4500(1.08)^2
Therefore you can write the following equation
4500(1.08)ⁿ where n is the number of years
we need is in 2015 and so n=15 so we have
4500(1.08)¹⁵=14274.5 which you should probably round to 14275
The second one is very similar to the first
to get from 1990 to 1991 you would multiply 5000*.93
so our equation would be
5000(.93)ⁿ where n is the number of years
1990-2012 is 22 so we have
5000(.93)²²=1012.96 which rounds to 1013
Paula says that 2/3 is equivalent to 4/9 because 4 is a multiple of 2 and 9 is a multiple of 3. explain her error.
Answer:
Paula is wrong because, in order to be equivalent, the nominator and denominator of a fraction must have to be multiplied by the same number.
Step-by-step explanation:
Paula is wrong because, in order to be equivalent, the nominator and denominator of a fraction must have to be multiplied by the same number.
4/9 is basically obtained when we multiply the denominator of 2/3 by 2 and denominator by 3, which is wrong.
Thus, the correction is as follows:
Given the fraction
[tex]\frac{2}{3}[/tex]
Multiply the nominator and denominator of the fraction by 2
[tex]\frac{2\times 2}{3\times 2}=\frac{4}{6}[/tex]
Thus, the 4/6 is the correct equivalent expression of 2/3.

Your weekly base salary is $150. You earn $20 for each phone you taht you sell. The company policy is that as a part-time employee , the maximum you can earn each week is $950
Write and solve an inequality that represents the number of cell phones you can sell each week.
Answer:
You can sell at least 40 phones each week.
Step-by-step explanation:
Given that:
Weekly base salary = $150
Earning on each phone = $20
Maximum amount that can be earned each week = $950
Let,
m be the number of phones.
20m + 150 ≤ 950
20m ≤ 950 - 150
20m ≤ 800
Dividing both sides by 20
[tex]\frac{20m}{20}\leq \frac{800}{20}[/tex]
m ≤ 40
Hence,
You can sell at least 40 phones each week.
Does (3, 10) make the inequality y > 2x + 2 true?
Answer:
Yes, it makes it true
Step-by-step explanation:
Plug in 3 and 10 as x and y into the inequality:
y > 2x + 2
10 > 2(3) + 2
10 > 6 + 2
10 > 8
Since 10 is bigger than 8, this inequality is true.
So, (3, 10) makes the inequality true.

The percentage decrease in basketball participation from 2013-2014 to 2014-2015 is 0.35%.
What is the Percentage?The Latin term "per centum," which signifies "by the hundredth," was the source of the English word "percentage." Segments with a denominator of 100 are considered percentages. In other terms, it is a relationship where the worth of the entire is always considered to be 100.
As per the given information in the question,
Number of basketball participants in 2013-2014 = 974,398
Number of basketball participants in 2014-2015 = 970,983
Then, the percentage decrease in the participants,
% decrease = (974,398 - 970,983)/ 974,398 × 100
% decrease = 0.35%.

At the end of 2005, this price was `\$513.` At the end of 2015, it was `\$1060.` By what percentage did the price per ounce of gold increase?
Answer: The price per ounce of gold increases by 106.63%.
Step-by-step explanation:
Given: Price in 2005 = $ 513
Price in 2015 - $ 1060
Now , [tex]\text{Percentage increase in price}=\dfrac{\text{Change in price}}{\text{ Initial price}}\times100[/tex]
[tex]\Rightarrow\ \text{Percentage increase in price}=\dfrac{1060-513}{513}\times100\\\\=\dfrac{547}{513}\times100\\\\= 1.0663\times100\%=106.63\%[/tex]
