I THINK I GOT IT OMG THAT WAS SO HARD

Answer:

z = 5

Step-by-step explanation:

[tex]\frac{4x^2y^7}{8x^3y^2} = \frac{y^z}{2x}[/tex]

It can be also written as -

[tex]\frac{2^2 \times x^2 \times y^7}{2^3 \times x^3 \times y^2} = \frac{1 \times x^0 \times y^z}{2 \times x^1 \times y^0}[/tex]

Using law of exponents , lets solve this.

[tex]=> 2^{(2-3)} \times x^{(2-3)} \times y^{(7 - 2)} = \frac{1}{2} \times x^{(0-1)} \times y^{(z-0)}[/tex]

[tex]=> 2^{-1} \times x^{-1} \times y^{5} = 2^{-1} \times x^{-1} \times y^z[/tex]

[tex]=> \frac{y^5}{2x} = \frac{y^z}{2x}[/tex]

[tex]=> y^z = y^5[/tex]

[tex]=> z = 5[/tex]

3×- 5 =16 help please​

Answers

Answer:

x = 7

Step-by-step explanation:

Given

3x - 5 = 16 ( add 5 to both sides )

3x = 21 ( divide both sides by 3 )

x = 7

Answer: X= 7

Explanation:
(you need to get x by its self)

Step 1- add the (-5) over to the 16

Because to get rid of a negative or minus sign you need to do the opposite which is addition.

You’ll get: 3x=21

Step 2- divide the 3 off from 21
Because the ‘3x’ is acting as multiplication, and the opposite of multiplication is division

You’ll get: X=21/3
Which is X=7

What type of government was in effect in Germany at the time of the Holocaust?FREE ANSWER ;;;;;;;;1. A direct democracy involves democracy in its purest form. All individuals participate at an equal level. This means that all people vote on every single aspect. A drawback of this is when a society becomes too large and it is difficult to keep track of all of the votes or to find a common ground among the people. This can be resolved by having home ballots so that people can mail in their votes. 2.
