Answer:
-2
Step-by-step explanation:
(5 - a) = 20 + (6a -1) . . . . . 5-a is 20 greater than 6a-1
5 = 7a +19 . . . . . . . . . . . . . add a, collect terms
-14 = 7a . . . . . . . . . . . . . . . subtract 19
-2 = a . . . . . . . . . . . . . . . . divide by 7
The value of the variable is -2.

<u>Check</u>
5 - (-2) = 7
6(-2) -1 = -13
7 is 20 greater than -13, so the answer checks OK.

Answer:
number of pots = p + 25
Explanation:
On weekends, Noah makes 11 pots more than the normal weekdays.
We are given that the equation representing the number of pots is:
number of pots = p + 11
Now, Noah made 14 pots more that his usual numbers, this means that we will add 14 to the usual number of pots that he makes.
Therefore, the equation will become:
number of pots = p + 14 + 11
number of pots = p + 25
Hope this helps :)
Answer:
Precision = 0.625
Recall = 0.5
Step-by-step explanation:
Data:
Let: total documents = 10
relevant documents = 5
if 2 documents are removed, the total number of documents remaining will be
documents remaining = total - 2 documents
= 10 - 2
= 8 documents
therefore, the precision will be = 
Recall =
