The given options are:

  • (A)x+y = 20
  • (B)7 apps and 14 movies
  • (C)x-y= 20
  • (D)y=-x+ 20
  • (E)8 apps and 12 movies
  • (F)xy= 20

Answer:

  • (A)x+y = 20
  • (D)y=-x+ 20
  • (E)8 apps and 12 movies

Step-by-step explanation:

If Elizabeth has a combined total of 20 apps and movies.

Where:

Number of apps=x

Number of Movies =y

Then:

Their total,

  • x+y=20 (Option A)

If we subtract x from both sides

x+y-x=-x+20

  • y=-x+20 (Option D)

In Option E

8 apps and 12 movies  add up to 20. Therefore, this could also apply.

Answer:

y= -x+20  and 8 apps and 12 movies

Step-by-step explanation:

Just took the test and these two were the only two that were right.  I don't know why x+y=20 was not correct but it wasn't.   Good luck!

What is a number between 4.1 and 4.11? I got it wrong. I put 4.01...what did I do wrong???
Nesterboy [21]
So, 4.01 is less than 4.1. Think of it as 4.10 and 4.01, 1 is less than 10. One you could have put is 4.101, because it is more than 4.1 and less than 4.11

What is the mean of the values in the dot plot?
sergij07 [2.7K]
First, write out all the values:
40,41,41,45,48,48,49,49,49,50

Then to find the mean, you add all the values and divide by the number of values (there are 10 values)
(40+41+41+45+48+48+49+49+49+50)/10
460/10
=46

Hope this helps
