Answers

Let’s condense the original expression and see if that’s one of the answers

-1/2(-3/2 x + 6x + 1) - 3x

First we distribute the -1/2

((-1/2)(-3/2 x) + (-1/2)(6x) + (-1/2)(1)) -3x

3/4x - 3x - 1/2 -3x

Combine like terms

(3/4 x - 3x - 3x) -1/2

-21/4 x - 1/2

We could make this a mixed number

-5 1/4 x - 1/2

(Mixed number: 5 times 4 plus one gets the numerator)

So the answer is D

The net of a rectangular prism is shown below. What is the total surface area of the prism?

Answers

Answer: 40.5

Step-by-step explanation: The way you get the surface area is by multiplying the numbers given, the rectangles are given as being 1.5 x 6, and the squares at 1.5 x 1.5, so you would multiply those, and then multiply them by the number of shapes that are the same size.

The rectangles would be;

1.5 x 6 = 9

9 x 4 = 36

The squares would be;

1.5 x 1.5 = 2.25

2.25 x 2 = 4.5

Now add the final numbers together to get the final surface area;

36 + 4.5 = 40.5

What is the explicit function that can be used to determine the number of people remaining in the nth round?
Of(n) = -2n + 27
of(n) = -2n + 29
f(n) = 2n + 27
f(n) = 2n + 29

Answers

of(n) = -2n + 29

1. find the difference
25-27= -2
23-25= -2
...
that’s your first part of the equation (-2n...)

2. get your first term and do the inverse function

so because it’s -2, you’ll add 2 to your first term which is 27

27+2= 29

3. -2n + 29

Lilliana is training for a marathon. She runs the same distance every day for a week. On Monday,
Wednesday, and Friday, she runs 4 laps on a running trail and then runs 6 more miles. On Tuesday and
Sunday, she runs 6 laps on the trail and then runs 2 more miles. On Saturday, she just runs laps. How
many laps does Lilliana run on Saturday?

Answers

Answer:

7

Step-by-step explanation:

Let's call x the amount of miles that equal a lap.

So on Monday Wednesday and Friday, she runs 4x + 6 miles.

On Tuesday and Sunday she runs 6x + 2 miles.

And the problem says that she runs the same distance every day, so that means that

4x + 6 = 6x + 2

Now we solve that equation:

4x + 6 = 6x + 2

6 = 6x + 2 - 4x

6 - 2 = 6x - 4x

4 = 2x

x = 2

After that we choose either 4x + 6 or 6x + 2 to calculate the distance she runs on per day by replacing the x with a 2.

4(2) + 6 = 14

6(2) + 2 = 14

Finally we just divide the amount of miles (14) by the amount of miles per lap (2).

14/2 = 7 laps
