2 (-n -3) -7 (5 + 2n)

Answers

Answer 1

Answer:

Answer: -16n-41

Step-by-step explanation:

first, distribute 2 through the parentheses:

2(-n-3)-7(5+2n) = -2n-6-7(5+2n)

second, distribute 7 through the parenthesis:

-2n-6-7(5+2n) = -2n-6-35-14n

Collect like terms:

-2n-6-35 and -16n-6-35

Calculate the difference:

-2n-6-35-14n = -16n-41

SOLUTION:

-16n-41

Does (-15, -691) make the equation y = -51x - 74 true?

Answers

Well, we can input both variables to check and see if the numbers hold.

-691 = -51(-15) - 74

-691 = 765-64

-691 = 701

(-15, -691) does not make the equation true.

Answer:

701 ≠ -691

Start at 125 create a pattern that subtracts 6 from each number

Answers

In this question, you are asked to make a pattern start with 125 with 6 less number each pattern. Then the pattern equation would be: 125-6x where x is determined by the position of the number.

The question doesn't specify how many numbers in the pattern that needs to be written but the pattern should be like this: 125, 119, 113, 107, 101, 95, 89, 83, 77

Which equation gives the value of the circumference, C, of a circle with a diameter of 48 feet?

Answers

An equation that represents the value of the circumference, C, of a circle with a diameter of 48 feet is C=2π×24.

What is the circumference?

The circumference is the length of any great circle, the intersection of the sphere with any plane passing through its Centre. A meridian is any great circle passing through a point designated a pole.

Given that, a circle with a diameter of 48 feet.

Here, radius = Diameter/2

Radius = 48/2 = 24 feet

We know that, the circumference of a circle is 2πr.

Now,

C=2π×24

C=2×3.14×24

C=150.72 feet

Therefore, the circumference of a circle is 150.72 feet.

Melissa plans to purchase a pair of jeans for $39.95. She wants to bring enough money to pay for the jeans plus the sales tax, which is 8.25%. What is her total, including sales tax?

Answers

You have to calculate the 8.25% of $39.95, then add the numbers together.
So: 8.25% of 39.95 = 3.3 (approximately)
The total is 39.95 + 3.3 = 43.25

Another method is to simply calculate the 108.25% of 39.95, you can get this by multiplying 39.95 with 1.0825.
