Answer:

x = -3

Step-by-step explanation:

4x - 1 = -13

add 1 to each side

4x = -12

x = -3

Answer:

x = -3

Step-by-step explanation:

Add 1 to both sides to, this gives you 4x = -12. then divide both sides by 4, which would give you x = -3.

Answer:

-8n² - 8n + 3

Step-by-step explanation:

Combine like terms (terms with the same variables, as well as the same amount of that variable).

(4n⁴ - 8n + 4) - (8n² + 4n⁴ + 1)

First, distribute the negative sign to all terms within the second parenthesis:

4n⁴ - 8n + 4 - 8n² - 4n⁴ - 1

Combine like terms:

(4n⁴ - 4n⁴) - 8n² - 8n + (4 - 1)

-8n² - 8n + 3

-8n² - 8n + 3 is your answer.

Answer:

Option 3

Step-by-step explanation:

Answer:

26/x = 13

x = 2

Step-by-step explanation:

2(x - 4) = 4

2x - 8 = 4

2x = 4 + 8

2x = 12

x = 12/2

x = 6

26/x = 13

Cross product

26 = x * 13

26 = 13x

x = 26/13

x = 2

- 3.8x = -7.4

x = -7.4 / -3.8

x = 1.95

4(x - 1) - 3(x - 2) = -8

4x - 4 - 3x + 6 = -8

x + 2 = -8

x = -8 - 2

x = -10

Answer:

80.45 inches

Step-by-step explanation:

Last year Stevie was 281/4 inches tall, which is: 70.25 inches (70 1/4)

He has grown 51/5 inches which is: 10.2 inches (10 1/5)

70.25 inches (last years height) + 10.2 inches (how many he has grown) = 80.45 inches

Stevie is 80.45 inches tall now.

Notice that v points into the third quadrant since both of its components are negative. If you want a vector to point in the same direction, it would need to have the same sign on its components. So C is the correct choice.

The factor of 1/√80 comes from normalizing the vector v. Its norm/magnitude is

|v| = √((-4)² + (-8)²) = √(16 + 64) = √80

so the unit vector that points in the same direction as v is simply v / |v|.

Answer:

z = 9

Step-by-step explanation:

JH is a perpendicular bisector of Δ IJK.

Thus the triangle is isosceles with

JK = JI , that is

7z = z + 54 ( subtract z from both sides )

6z = 54 ( divide both sides by 6 )

z = 9

The value of given x is 16

Given that:

Perimeter of square = 76 cm

Side of square = (x + 3)

Find:

The value of x

Computation:

Perimeter of square = 4[Side]

76 = 4[x + 3]

76 = 4x + 12

4x = 76 - 12

4x = 64

x = 64 / 4

x = 16

The value of x = 16

Answer:

In 2014, the population is of the United States was about 318,900,000 people. Choose the best approximation of the United States Population in 2014.

people

people

Answer:

people

Step-by-step explanation:

Given

US Population in 2014: About 318,900,000

Required

Approximate

From the given options, it's seen that the population of US is to be approximated to one significant digit and the result should be presented in standard form

So, the first step is to write out the population

318,900,000

As a general rule,

Category 1: Digit 0-4 are approximated to 0

Category 2: Digit 5-9 are approximated to 1

Since, we are approximating to one significant digit, only the first digit is needed, others are to be approximated.

The first digit is 3, meaning that approximation starts from the next digit which is 1

Approximating 318,900,000 will give 300,000,000 because "1" falls in category 1 as illustrated above.

The final step is to convert 300,000,000 to standard form.

There are 8 0s after 3.

Hence,

Conclusively, the approximation of 318,900,000 is  people

Step-by-step explanation:

Answer: 305 people

Step-by-step explanation:

The total number of people sampled is:

= 71 + 22 + 27 + 83

= 209

Out of this 209, the number of people who prefer Vanilla and cookie dough ice cream is:

= 71 + 27

= 98 people

In a sample of 209 people, 98 people would prefer either vanilla or cookie dough. In 650 people, that number would therefore be:

= 98/ 209 * 650

= 305 people

Answer:

1713 milliliters

Step-by-step explanation:
