Answer:

X equals 10

Step-by-step explanation:

4X centimeters divided by x cm equals 4. Since we know that were divided by 48 CM / 4 equals 12. That means that (x + 2) cm equals 12. That means that x is equal to 10

Step-by-step explanation:

\frac{4x}{x}  =  \frac{48}{(x + 2)}  \\ 4 =  \frac{48}{(x + 2)} \\ 48 = 4(x   + 2) \\ 48 = 4x + 8 \\ 48 - 8 = 4x \\ 40 = 4 x \\  \frac{40}{4}  =  \frac{4x}{4}  \\  = x = 10

ICE Princess25 [194]

There would be 173,535 lionfish after 6 years.

Since lionfish are considered an invasive species, with an annual growth rate of 67%, ya scientist estimates there are 8,000 lionfish in a certain bay after the first year, A) to write the explicit equation for f (n) that represents the number of lionfish in the bay after n years; B) determine how many lionfish will be in the bay after 6 years; and C) if scientists remove 1,200 fish per year from the bay after the first year, determine what is the recursive equation for f (n); the following calculations must be performed:

  • A)
  • 8000 x 1.67 ^ n = f  
  • B)
  • 8000 x 1.67 ^ 6 = X
  • 8000 x 21.691961596369 = X
  • 173,535.692770952 = X  
  • C)
  • (8000 - 1200 x 1 ^ n) x 1.67 ^ n = f

Therefore, there would be 173,535 lionfish after 6 years.

Gia got some books from Library yesterday she got five books today Gia returned three books Gia has six books how many books did
makvit [3.9K]

Answer: 4


Explanation:


You can write an algebraic expression to represent the sequence with the books in this way:

  • yesterday she got five books: 5
  • today returned three books: - 3
  • how many books did Gia have to begin: n
  • At the end she has six books, which means that you can set an equality:

       n + 5 - 3 = 6

Now you follow these steps to clear the unknown:

  • do the operations in the left side: n + 2 = 6
  • use subtraction property of equality: n = 6 - 2
  • do the operations: n = 4

And that is the number of books whith which Gina started: 4
