Alright! In order to solve this you have to work backwards. So, you know her end total is 36. And to get to that she bought 16 books. So:

36 - 16 = 20.

So, after she sold half her books she had 20. To find how many she started with you do the opposite of dividing by 2, multiplying by 2. So:

20 x 2 = 40.

She started with 40 books.

Let us assume the number of books with which Jill started = x
Number of books that Jill sold first is half and then Jill again bought 16 books, making her total number of books to 36.
Then
(x/2) + 16 = 36
(x/2) = 36 - 16
(x/2) = 20
x = 20 * 2
   = 40

From the above deduction, it can be easily concluded that the number of books that Jill started with was 40. I hope that the procedure is clear enough for you to understand.

You got add all the numbers up and divide it by how many numbers there are to get the average.
9.4 +9.7 + 9.9 + 9.8 = 38.8 divided by 4 =9.7 is Joey's average.
9.5 +9.2 +9.7 +9.6 =38 divided by 4 = 9.5 is Carlos' average.
Joey has more average by 0.2.

Each morning papa noted the birds feeding on his birdfedder . So far this month he had seen 59 blue jays ,68 black crows , 12 re
Oduvanchick [21]
To solve this question, you need to first look at the total amount of birds and then at the percentage of the blue jays that fed on the bird feeder out of all the other birds.

To calculate the total you add them all together:
59+68+12+1 = 140 birds 

Then the percentages of the blue jays that fed on his bird feeder are:
59/140 *100 = 42.143%

You want to see how many blue jays we can expect to see out of 300 birds. 
So you divide 300 by 100 to see what 1% is = 3 birds 

Then you multiply this amount (1% = 3 birds) by 42.134% which is the percentage of blue jays we can expect to see out of the 300 birds. 
3*42.134 = 126.43 

You round this off to 126 because you cant expect to see half a bird. Even if the answer had been 126.9, you would have rounded it of to 126 because no matter how close it is to the next whole number; you either have a whole bird or you don't.

Final Answer = 126

Does the equation 6x+35=-6x+35 have infinitely many ,one or no solution​
marissa [1.9K]

Answer:

One solution

Step-by-step explanation:

6x+35=-6x+35

Add 6x to both sides (addition property of equality)

12x+35=35

Subtract 35 from both sides (subtraction property of equality)

12x=0

Divide both sides by 12 (division property of equality)

x=0

Therefore there is only one solution, 0.
