11 blue
2 green
7 brown
total is 20 card
7 out of that 20 are brown
so x out of 100% are brown
7/20=x/100 - cross multiply
700=20x
x=700/20
x=70/2
P-1=5p+3p-8
p-1=8p-8
-1=7p-8
7=7p
p=1
hope this helps :)
Answer:
640 foxes
Step-by-step explanation:
The actual formula is 
Now that we have the real formula we would need to find out how many 13 year periods exist in the 26 years that are being used in the question. We calculate this by simply dividing 26 by 13.
26 / 13 = 2 periods
Therefore, now that we know there are 2 periods of 13 years in the 26-year span, we plug this value into the formula and solve for y...
Finally, we can see that there should be 640 foxes after 26 years.

Answer:
Hi there!
Your answer is:
x= 1
Step-by-step explanation:
Goal- get all X's on one side, and all whole numbers on the other
2+3x -x = 4x
First, combine like terms on each side of the equal sign
2+ 2x = 4x
Next, think about the additive inverse property. What, added to 2x, equals 0? 2x + (-2x) =0! So, we <u>subtract</u> 2x from both sides!
2= 4x-2x
Simplify
2= 2x
Divide both sides by the coefficient of x (in this case, 2)
2/2 = x
2/2 is equal to 1
1= x
Hope this helps!
