Answer:

2)

[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]

Answer:

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°

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.

Answer:

22 meters

Step-by-step explanation:

If the penguin goes from 15 meters above sea level to sea level (0 meters), they traveled 15 meters in elevation.

Then they traveled another 7 meters when going 7 meters below sea level.

15 + 7 = 22

Answer:

52 cm (?)

Step-by-step explanation:

I'm assuming this is a rectangle.

you take each of the sides(with rectangles, two of each sides will have the same length) and add them together.

15 + 15 + 11 + 11 = 52

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.

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

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.

Answer:

true

Step-by-step explanation:

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.

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]

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

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.

Answer:

Step-by-step explanation:

An equation is like a sentence, just using a different language. Mathematical equations are telling you to do something, giving you information on how to respond, or come up with an answer. It's up to you to learn this language. However, once you know it, you can write in this language! You, too, can write algebraic equations.

Parts of a Mathematical Equation

A mathematical equation, also known as a statement, shows that two separate expressions are equal. The two expressions are usually connected by the "equal-to" (=) sign. You can find the expressions in a mathematical statement by looking at the left-hand side and the right-hand side of the equation, using the = sign as the point of reference.

Example: 2x + 3 = 11

It can be helpful to view equations as a scale in which weights are used to keep it balanced. The scale is balanced when what is placed on the right-hand side is equal in weight to what is on the left-hand side. Solving an equation can also be thought of in terms of adding weight to the left or right-hand side of the scale to balance it out.

Finding the solution to the equation involves manipulating the weights. Whatever is done on the right-hand side of the scale must also be done on the left-hand side to keep the scale balanced.

Your tools for this happen to be, most commonly, addition, subtraction, multiplication, or division.

Answer:

An equation uses symbols and numbers there are SO many equations you could make for example an easy one 6 x 5 = 30 there are two numbers you multiply to get a product. Whenever you write an equation you always put an equal sign which is this: = . This shows what you get from the equation. There are main parts the =, +, -, x, ÷ . All represent what you do to the two numbers you put on both sides of it.
