Jane had several stamps. She gave 10 of them to her friend. Afterwards, Jane’s mom bought her twice as many stamps as she had in
Bumek [7]
The answer is 20 stamps. 

You can solve this by forming an equation with. 

We know that she has a total of 50 at the end. So we will put the 50 stamps at the end of the equation and derive for the unknown. 

She first gave 10 to her friend. This means we subtract first 10 from the unknown. Let x represent the unknown. 

x-10

Afterwards Jane's mom bought her twice as many as she had at the beginning. So we know that we add twice as much as the unknown. 

x-10+2x = 50

Now we solve. Let's arrange our terms by combining like terms:
3x - 10 = 50

Now we transpose the 10 to the other side of the equation:
3x = 50 + 10
3x = 60

And finally we transpose the 3 by the x to isolate x:
x = 60/3
   = 20 

She had 20 stamps in the beginning.

tatiyna

Answer:

100 rabbits

25 foxes

Step-by-step explanation:

Because if there are 100 rabbits, we already know how many rabbits there are so, since we are trying to figure out how many foxes there are we take the 100 ÷ 4 = 25 foxes.

Solve the equation for all values of xx.<br> 9x^2-64=<br> 9x <br> 2<br> −64=<br> \,\,0<br> 0
Keith_Richards [23]

Factor:

9x^2 - 64

= (3x)^2 - 8^2

= (3x + 8)(3x - 8)

If you want to solve it, let the equation equal zero

(3x + 8)(3x - 8) = 0

3x + 8 = 0 ; x = -8/3

3x - 8 = 0 ; x = 8/3

Solutions: x = -8/3 and x = 8/3
