[tex]2x + 6x + 8 = 32[/tex]
collect like terms
[tex]8x + 8 = 32[/tex]
move the constant to the right hand side and change its sign.
[tex]8x = 32 - 8[/tex]
Subtract the numbers
[tex]8x = 24[/tex]
Divide both sides of the equation by 8
[tex]x = 3[/tex]

Find each angle measure to the nearest degree please help
9514 1404 393
Answer:
4°48°Step-by-step explanation:
The inverse cosine function of your calculator is used to find the angle from the cosine value. (Be sure your calculator is set to 'degrees' mode.)
1) A = arccos(0.9976) ≈ 4°
2) U = arccos(0.6691) ≈ 48°
A population of 2000 fish increases at an annual rate of 7.5%. Write the model, then predict how
many fish will there be in 10 years?
Answer:
The model is [tex]P(t) = 2000(1.075)^{t}[/tex].
There will be 4122 fish in 10 years.
Step-by-step explanation:
Exponentially increasing population:
An exponentially increasing population can be represented by the following model:
[tex]P(t) = P(0)(1+r)^t[/tex]
In which P(t) is the population after t years, P(0) is the initial population, and r is the growth rate, as a decimal.
A population of 2000 fish increases at an annual rate of 7.5%.
This means that [tex]P(0) = 2000, r = 0.075[/tex]
So
[tex]P(t) = P(0)(1+r)^t[/tex]
[tex]P(t) = 2000(1+0.075)^t[/tex]
[tex]P(t) = 2000(1.075)^{t}[/tex]
This is the model.
How many fish will there be in 10 years?
This is P(10).
[tex]P(t) = 2000(1.075)^{t}[/tex]
[tex]P(10) = 2000(1.075)^{10} = 4122[/tex]
There will be 4122 fish in 10 years.

A supermarket has found that the relationship between a day's high temperature and the amount of money taken in on that day from frozen yogurt sales can be modeled by the equation y = 4x + 164, where x is the high temperature in degrees Fahrenheit and y is the amount taken in from frozen yogurt sales in dollars. Which of these statements is true according to the model?
Answer:
On a day when the high temperature is 79° F, the supermarket can expect to take in $380 in frozen yogurt sales.

Kevin earns $12.00 for every 5 story problems he writes. How much would Kevin get for writing 12 problems?
Answer: $28.80
Step-by-step explanation:
We can start by finding the unit rate. How much money does Kevin earn from writing 1 story problem?
We can find how much Kevin earns from writing 1 story by dividing 12 by 5.
12 ÷ 5 = 2.4.
Therefore, Kevin earns $2.40 for every story he writes.
Now we have to find how much Kevin earns from writing 12 story problems. If Kevin earns $2.40 for every story he writes, then we should mutliply that by 12 to find how much money Kevin earns for writing 12 problems.
2.40 x 12 = 28.8.
In conclusion, Kevin earns $28.80 dollars for writing 12 problems.
Guys I need help what is 6 divided by 398
find the slope of the line
Answer:
The slope of the line is: 1
Step-by-step explanation:
Use the equation
[tex] \frac{y2 - y1}{x2 - x1} [/tex]
Use the two sets of points given to you to slve the equation.
Assign the points their variables:
x1 y1 x2 y2
(4, 4) (8, 8)
Insert the numbers into the equation:
[tex] \frac{8 - 4}{8 - 4} [/tex]
Simplify:
[tex] \frac{4}{4} = 1[/tex]
Ms. Ortiz borrows $2.50 every day for a school week (5 days) to buy a bacon egg and cheese. How much does
she owe by the end of the week? (Use negative numbers to show how much she owes
It’s multiplying signed numbers
Answer: She will owe $12.50 at the end of the week, and her account balance will be -12.50 dollars.
Step-by-step explanation:
A school week is 5 days. If Ms. Ortiz borrows $2.50 every day, then we will have to multiply 2.50 by 5 to find how much Ms. Ortiz owes at the end of the week.
2.50 x 5 = 12.5, or $12.50.
Therefore, Ms. Ortiz owes $12.50 at the end of the week, and her account balance will be -12.50.

Maribel is packing boxes of canned goods for the food drive. Each box can hold 8 books. How many boxes are needed for 122 books?
answer is:16 books
Answer:
16 boxes will be needed for 122 books.
Step-by-step explanation:
Given that,
Each box can hold 8 books.
We need to find the number of boxes needed for 122 books. It can be calculated as follows :
[tex]\dfrac{122}{8}[/tex] = 15.25
It means 15 boxes can be filled and 16 boxes will be needed for 122 books.
Which equation represents the relationship between the x-values and the y-values in the table?
Answer:
y = 10x + 5
Step-by-step explanation:
Remember when x = 0 that is when you get your y-intercept. So when you look at the chart you can see that your answer has to have a +5 so now you are down to only to answers.
Now slope is the change of Y over the change of X , so 5 to 55 is 50
and 0 to 5 is 5
[tex]\frac{y}{x}[/tex]=[tex]\frac{50}{5}[/tex] and that equals 10
put both parts together and
y = 10x + 5

seven more than twice a number is greater than negative fifteen
Answer: 2n > -15
Step-by-step explanation:
We can use the variable n to show the unknown number.
It says that there is twice a number, meaning two of an unknown number. We can show it by using the term 2n.
It also states that 2n is greater than -15. Because of that, we can use the equation 2n > -15, to show that 2n is greater than -15.
(Quick note: The variable n just represents the unknown number, you can subsitutue any variable into its place.)
The Inequality that shows seven more than twice a number is greater than negative fifteen is; 2n > -15
What is inequality?Inequality is defined as the relation which makes a non-equal comparison between two given functions.
We can consider the variable n to show the unknown number.
That says, there is twice a number, meaning two of an unknown number. We can show it by using the term "2n".
It states that seven more than twice a number is greater than negative fifteen
MEans 2n is greater than -15.
we can use the equation 2n > -15, to show that 2n is greater than -15.
