D. Write the solution as an ordered pair. E. Check the solution with the equation not used in Step C.

Answers

Answer 1

Answer: X=29

Step-by-step explanation:

First you substitute the x's: 2(3y-1)-5y=8

Then you open parenthesis:6y-2-5y=8

Combine like terms: y-2=8

Bring the 2 to the other side: y=10

Now you substitute the y with the answer: x=30-1

Easy equation: x=29

Answer 2
The answer will be x=29

Students recorded the total number of pages and chapters in each of several books on the scatterplot.







Based on the scatterplot, which is the best prediction of the total number of pages in a book with 4 chapters?

Answers

Answer:

120

Step-by-step explanation:

based on the plot the closest number to the patter seem to be around 100 but its not 90 as 90 would be below so it has to be about 12

The best prediction of the total number of pages in a book with 4 chapters could be 120 pages.

How does the dot plot work?

Suppose we're measuring something whose values are numeric. For each value of that thing we observe, we plot a dot above that value in the number line. Thus, the total number of dots in the dot plot tells us the total number of observations of the values of that thing we did.

We have been given that Students recorded the total number of pages and chapters in each of several books on the scatterplot.

Based on the scatterplot, we need to find the best prediction of the total number of pages in a book with 4 chapters.

According to the scatterplot, we can see that the closest number to the pattern seems to be between 100 and 120.

Therefore, the best prediction of the total number of pages in a book with 4 chapters could be 120 pages.

Answer:

1 inch represents 1/3 foot

Step-by-step explanation:

Scale = 51 inches

Actual = 17 feet or 204 inches

Use a ratio to compare the two 204:51 or 204/51 = 4

This means that the actual size is 4 times the scale size

Take 1 inch in the scaled size and multiply it by 4 to get the actual size to get 4 inches

4 inches = 1/3 foot, therefore 1 inch represents 1/3 foot

Plz help it due in 10 minutes.

Answers

Answer:

6 meters

Step-by-step explanation:

Set up a proportion as 18/x=6/2. The meters are unknown, so that's what the x value represents. Then, cross multiply (18 times 2 and 6 times x) to get 36=6x. By dividing both sides of the equation by 6, you'll get 6 meters as your answer.
