PLEASE HELP ME I DON’T GET IT

Answer:

D) -5 1/4

Step-by-step explanation:

In this problem there is -3/4 foot change every year and you are trying to see how much changes over 7 years. That means you are multiply the 7 by -3/4. To do that you need to change the 7 into a fraction.

7= 7/1, now you are going to mulitpy the two fractions.

This line represents the numerators:     7 times -3= -21

This line represents the denominators: 1 times 4 =  4

Now that we know our fraction is -21/4 we simplify.

The simplest form you can get is -5 1/4.

I hope this helped, let me know if you have any questions!! :)

I need help because the last person that helped with this question made me click a link and it made me download a bunch of virus-helping apps and they are so annoying. And I never even got the darn answer!

The table and the graph each show a different relationship between the same two variables, x and y:

A table with two columns and 5 rows is shown. The column head for the left column is x, and the column head for the right column is y. The row entries in the table are 3,270 and 4,360 and 5,450 and 6,540. On the right of this table is a graph. The x-axis values are from 0 to 10 in increments of 2 for each grid line. The y-axis values on the graph are from 0 to 800 in increments of 160 for each grid line. A line passing through the ordered pairs 2, 160 and 4, 320 and 6, 480 and 8, 640 is drawn.

How much more would the value of y be in the table, than its value on the graph, when x = 11?

The five starters for the Seaside Shooters scored all the team’s points in the final basketball game of the season. Regina Reporter covered the game, but later her notes were accidentally destroyed. Fortunately she had recorded some interviews with the players, but when she played them back, only a few quotes seemed relevant to the scoring. She knew the final score was 95-94. Using the players’ observations, determine how many points each of them scored.

Kellene: Everybody’s totals were odd numbers.
Sara: Donna was fourth highest with 17 points. I scored 12 more points than Kellene.
Martina: Kellene and I scored a total of 30 points. I outscored her.
Heather: The last digit in everybody’s score was different.
Donna: Our highest scorer had 25 points.
