HELP I DONT KNOW THE ANSWER

Answer:

3/4; 1/4, 1/4, 1/4

Step-by-step explanation:

The intent here is to let you demonstrate your understanding that multiplication by an integer is the same as repeated addition.

Your knowledge of fractions tells you ...

$\dfrac{1}{4}\times3=\dfrac{3}{4}$

The factor of 3 means this is equivalent to adding 1/4 a total of 3 times:

$\dfrac{1}{4}\times3=\dfrac{1}{4}+\dfrac{1}{4}+\dfrac{1}{4}$

Move all the logarithms on the left hand side, and all the constants on the other:

$\log_2(x-2) - \log_2(x) = -1$

Use the rule of logarithms

$\log_a(b) - \log_a(c) = \log_a\left(\dfrac{b}{c}\right)$

To rewrite the equation as

$\log_2\left(\dfrac{x-2}{x}\right) = -1$

Evaluate 2 to the power of each side:

$\dfrac{x-2}{x} = 2^{-1} = \dfrac{1}{2}$

Multiply both sides by 2x:

$2(x-2) = x \iff 2x-4 = x \iff x = 4$

Nick currently has 7,200 points in his fantasy baseball league, which is 20% points than Adam. How many points does Adam have?

Dovator [93]

Heya!!!

Answer to your question:

Let Adam's points be x.

Nick has points =7200=20%of x+x

20/100 *x + x=7200

x/5 +x=7200

6x/5=7200

x= 7200*5/6

x=6000

Adam has 6,000 points.

Hope it helps *_*
