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

help me with this question please, explain why u choose that answer and show ur steps

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 median would be the middle data point. Let’s list the points

Put them in order from least to greatest

25, 26, 31, 32, 39, 57

There is an even amount of data so take the two center points and divide by 2

31 + 32 = 63

Divide by 2

31.5

There would be an average of 31.5 strokes
31.5 strokes is the answer

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
