Answer: D. X=22 and 22=X. *The answer must have a positive sign.*

Explanation:

Addition property of equality is adding the same number to both sides of an equation "it's does not change the equation."

First, add 28 both sides of an equation.

2x-28+28=16+28

Then, simplify.

28+16=44

2x=44

Next, divide by 2 both sides of an equation.

2x/2=44/2

And finally, simplify by equation. And divide by the numbers.

44/2=22

22*2=44

44/22=2

2*22=44

X=22 and 22=X

Hope this helps!

Thanks!

Have a great day!

2x - 28 = 16

Add 28 to both sides

2x = 44

Divide both sides by 2

x = 22

4(3x^2y^4)^3 / (2x^3y^5)^4

tatyana61 [14]

Solving the expressions $\frac{4(3x^2y^4)^3}{(2x^3y^5)^4}$ we get $\frac{27}{4x^{6}y^{8}}$

Step-by-step explanation:

We need to Solve the expression: $\frac{4(3x^2y^4)^3}{(2x^3y^5)^4}$

Solving:

$\frac{4(3x^2y^4)^3}{(2x^3y^5)^4}$

$=\frac{4(3^3x^6y^{12})}{(2^4x^{12}y^{20})}\\=\frac{4(27x^6y^{12})}{(16x^{12}y^{20})}\\=\frac{108x^6y^{12}}{16x^{12}y^{20}}$

Applying exponent rule: $\frac{x^a}{x^b}=x^{a-b}$

$=\frac{108x^{6-12}y^{12-20}}{16}\\=\frac{27x^{-6}y^{-8}}{4}$

Another exponent rule says: $x^{-a}=\frac{1}{x^a}=$

$=\frac{27}{4x^{6}y^{8}}$

So, solving the expressions $\frac{4(3x^2y^4)^3}{(2x^3y^5)^4}$ we get $\frac{27}{4x^{6}y^{8}}$

Rayshawn has a certain amount of money if he spends $20 then he has 1/3 of the original amount how much money did Rayshawn have

erik [133]

Answer:

Rayshawn originally had $30.

Step-by-step explanation:

i) Rayshawn has a certain amount of money. Let us say this amount is $x.

ii) Rayshawn spends $20 which means that he is left with $(x - 20)

iii) it is also given that amount of money left after spending $20 is $\dfrac{1}{3}$ of the original amount, $x, the amount remaining is $\dfrac{\$x}{3}$ .

iv) from the information given in ii) and iii) we get

$(x - 20) = $\dfrac{\$x}{3}$ , Therefore we get 3x - 60 = x , therefore 2x = 60,

Therefore x = $30. Rayshawn originally had $30.
