find three consecutive numbers such that three times the first number is equal to 9 more than the sum of the other two.
Answers
Answer:
12, 13, 14
Step-by-step explanation:
Three consecutive numbers means three numbers in a row, so if n is the first number, the second number is one more than n (which is n+1) and the third number is one more than that (which is n+2)
So three times (3 x) the first number (n) is equal to (=) nine more than (9 +) the sum of the other two ( (n+1) + (n+2) )
3 times n can be written as 3n
So 3n = 9 + (n+1) + (n+2)
3n = 9 + n + 1 + n + 2
3n = 9 + 1 + 2 + n + n
3n = 12 + 2n
Subtract 2n from each side
3n - 2n = 12 + 2n - 2n
1n = 12
n = 12
So the first number is 12, the second number is 12 + 1 (13) and the third number is 12 + 2 (14)
The numbers are 12, 13, 14

The amount of money and dollars that it cost to purchase x square feet of the carpet is given by f(x)= 8x the insulation feet is $125 more than 8% of the cost of the carpet right function of g that represents the insulation fee then use the function to find the insulation fee for 175 square feet of carpet
Answers
Answer:
The insulation fee for 175 square feet of carpet is $237.
Step-by-step explanation:
The amount of money, f(x), that it cost to purchase x square feet of the carpet is:
f(x)= 8x
The insulation fee,g(x), is $125 more than 8% of the cost of the carpet,f(x), we have
g(x)=8% of f(x)+125
[tex]\Rightarrow=\frac{8}{100}\times (8x)+125[/tex]
[tex]\Rightarrow=0.64x+125[/tex]
The insulation fee for 175 square feet of carpet,
i.e for x=175
[tex]g(x=175)=0.64\times175+125=237[/tex]
Hence, the insulation fee for 175 square feet of carpet is $237.
Given x∥y and m∠2=23° .
What is m∠7?
Enter your answer in the box.
Answers
Answer:
angle2=23°
angle7=angle5
angle2=angle6
so,angle8=23°
total angle = 180°
angle7=180°-46°=134°÷2=67°
Using corresponding angles are equal property we found that m∠7 = 157°
What are corresponding angles?When two parallel lines are intersected by an transversal line then the pair of angles formed on one same side of transversal on both parallel lines are corresponding angles. As in the figure attached ∠ 1 and ∠5 are corresponding angles.∠4 and ∠8 are also corresponding angles.
Corresponding angles are always equal.
Given that x and y are parallel lines.
Then ∠2 and ∠6 are corresponding angles , therefore m ∠2 = m ∠6
Given that m∠2 = 23°
⇒ m∠6 = 23°
As ∠7 and ∠6 are on same line hence they are supplementary
m∠7 + m∠6 = 180°
⇒m∠7 + 23° =180°
⇒m∠7 =180°- 23° = 157°
Therefore, the measure of angle ∠7 is 157°

[tex]\frac{-1}{2}[/tex] x 2y = 11
y = -11
[tex] \frac{ - 1}{ \: \: \: 2} y = \frac{1}{2} + 5[/tex]
[tex] \frac{ - 1}{ \: \: \:2} \times y = \frac{1}{2} + 5[/tex]
[tex] \frac{ - 1}{ \: \: \:2} \times y = \frac{11}{2} [/tex]
[tex]y = \frac{11}{2} \div \frac{ - 1}{ \: \: \:2} [/tex]
[tex]y = \frac{11}{2} \times \frac{ \: \: \: 2}{ - 1} [/tex]

[tex]y = - 11[/tex]
The value of y = -11

Find the slope of the line passing through each of the following pairs of po
(-6,0), (4,0)
Answers
Answer:
m = 0
Step-by-step explanation:
To find the slope of a line, use the equation:
m = y2 - y1 / x2 - x1
Then, substitute in numbers:
m = 0 - 0 / -6 - 4
m = 0 / -10
m = 0
Therefore, the slope of the line is 0, meaning it has zero slope.
On his way to the office each workday (Monday through Friday), Darrell walks by a charitable foundation with a donation bucket set out front. He has decided that he nts to try to be more charitable, so starting next week, he plans to put $1 in donation bucket every day he walks by. He has also estimated that he has already donated $23 to the foundation, Part if x represents the number of weeks thłt Darrell has been making a donation, write a recursive function to represent the total amount he has donated Explain your work
Answers
Answerer: Darrell has already donated $23 to the foundation, so f (0) =$23.
Because x represents the number of weeks, and Darrell is contributing $1 every day, Monday through Friday, he will contribute a total of $5 per week. So, the total amount donated will increase by $5 each week. Therefore, the recursive function will be f (x) =f(x - 1) + $5, where f ($23).
